welcome to Scaling UP! the podcast for
water treater by water treaters where
0:12.8
0:17.4
we’re Scaling UP on knowledge so we
don’t Scaling UP our systems
0:17.4
0:22.9
hello Scaling UP nation Trace Blackmore
here your host for Scaling UP h2o and
0:22.9
0:30.8
this is another pinks and blues episode
where I am answering questions based on
0:30.8
0:36.9
what the listeners have asked for and I
have themed this episode like I have
0:36.9
0:42.4
done some others I’ve received a lot of
questions based on this particular topic
0:42.4
0:48.8
so we’re just going to talk about this
topic now all these questions stem
0:48.8
0:55.4
around the proper way to calibrate your
equipment and specifically either the pH
0:55.4
1:01.6
or no RP probe or conductivity there’s a
lot of misinformation out there about
1:01.6
1:07.9
the right way to calibrate and when you
need to replace your conductivity meter
1:07.9
1:13.5
or your probes or whatever that may be
and I think a lot of that has to do with
1:13.5
1:21.2
how us the water treater truly take care
of our equipment so when we talk about
1:21.2
1:27.4
conductivity probes or pH probes or ORP
probes typically we’re talking about a
1:27.4
1:33.9
handheld meter that we’re using out in
the field but it could also be on the
1:33.9
1:38.0
controller itself on the device that’s
hanging on the wall that’s delivering
1:38.0
1:46.4
our program day after day you know these
probes are meant to fail eventually now
1:46.4
1:51.6
conductivity probes are a little bit
more durable than pH and ORP probes and
1:51.6
1:58.5
the PTSA probes that so many people are
using now but you have to understand the
1:58.5
2:04.8
way that many of these probes are built
they have a very specific shelf life and
2:04.8
2:10.6
as soon as they are built they are
starting to die it’s just the nature of
2:10.6
2:15.5
the beast so don’t think if you’ve
purchased one of these probes you’re
2:15.5
2:21.0
done and you never have to purchase it
again folks it’s just how they are
2:21.0
2:25.3
you will have to replace these probes
now how often you do that
2:25.3
2:34.2
I truly believe is based on how well you
take care of these probes so let’s get
2:34.2
2:41.1
into how to properly calibrate some of
these probes so what I’m doing now I’m
2:41.1
2:47.3
actually looking at my 6p my Rennell
meter and you can also substitute this
2:47.3
2:51.7
for the controller that you might be
having some issues with or another
2:51.7
2:56.9
handheld meter that you have in your
test kit it’s very important that you
2:56.9
3:02.2
know what the battery voltage is now I
say that you don’t really necessarily
3:02.2
3:06.8
have to get a multimeter out and read
the voltage but many of us don’t
3:06.8
3:12.4
understand what’s happening inside that
meter and what happens for example the
3:12.4
3:18.1
6p has a nine volt battery in it but it
doesn’t use nine volts it actually
3:18.1
3:25.3
stages that down to somewhere around six
volts so that battery is fine until it
3:25.3
3:31.8
reaches six volts and then it gives you
the low battery alarm folks if you’re
3:31.8
3:36.6
seeing the low battery alarm it’s very
possible that you do not have enough
3:36.6
3:41.7
voltage going through that meter to make
sure you’re getting an adequate response
3:41.7
3:49.1
to it nine times out of ten when people
have probes that aren’t holding
3:49.1
3:55.3
consistently their battery hasn’t been
replaced like it should what we do here
3:55.3
4:01.7
Blackmoor enterprises is we replace our
batteries on a regular basis not when
4:01.7
4:07.6
the meter says that they’re getting that
low battery light and that just ensures
4:07.6
4:13.4
that we’ve got a nice fresh battery in
there so we have plenty of voltage and
4:13.4
4:18.2
we don’t have to worry about that issue
so I know many of you out there are
4:18.2
4:23.4
thinking when was the last time I
changed the batteries in my meter if
4:23.4
4:28.0
that is you
go ahead and spend a few bucks and
4:28.0
4:33.8
change the batteries in your meter
I would also write down when it was that
4:33.8
4:38.5
you change those batteries and if you
have not changed them in a six month
4:38.5
4:42.6
period I would go ahead and change them
again depending on how much you’re using
4:42.6
4:48.5
that meter that might be too little but
it’s not too much I would say you want
4:48.5
4:53.1
fresh batteries in that meter at least
twice a year so after you change the
4:53.1
4:59.2
battery now you have to make sure that
the meter is clean and folks I got to
4:59.2
5:04.0
tell you that most of the problems
outside of not having enough voltage
5:04.0
5:09.9
going through a meter is because many
water treaters will take their sample
5:09.9
5:16.6
and they won’t clean their meter they’re
on site and things dry inside those cups
5:16.6
5:23.1
where those probes are and those create
havoc with our actual readings so when
5:23.1
5:27.6
you’re out there and you’re taking your
sample and you’re taking your reading
5:27.6
5:33.6
make sure that you have a deionizing
bottle with you and rinse that meter out
5:33.6
5:39.5
really well we like to rinse everything
at least three times and then store it
5:39.5
5:45.1
in the proper solution for example if it
was a pH probe we would store that in
5:45.1
5:51.0
the electrode storage solution which is
not the same as pH 4 buffer because pH 4
5:51.0
5:57.4
buffer has a red dye in it and that will
actually migrate into the pH probe and
5:57.4
6:02.3
cause problems so keeping the meter
clean on a consistent basis is very
6:02.3
6:08.1
important make sure that if you put any
sample into your meter you’re always
6:08.1
6:14.6
washing that out so there’s nothing to
dry and crystallize in any part of your
6:14.6
6:19.7
meter cups now on a regular basis you
want to make sure and you’re cleaning
6:19.7
6:25.9
your meter physically cleaning your
meter with I like to use simple green
6:25.9
6:30.4
that’s one of my favorite detergents
it’s actually made here in Lawrenceville
6:30.4
6:35.1
Georgia where our office is so please
patronize a local company I’m sure if
6:35.1
6:38.1
you go to Home Depot or anywhere where
you buy your
6:38.1
6:43.3
cleaning supplies you will find simple
green it’s a good degreaser it’s not
6:43.3
6:47.4
going to do a lot for mineral so
hopefully nothing’s dried out on you if
6:47.4
6:54.3
something like that has crystallised
acid such as your alkalinity buffer that
6:54.3
6:59.6
might help soluble eyes anything like
that that’s on there but normally you
6:59.6
7:05.0
can get away with the simple green if
you are rinsing your meter like I said
7:05.0
7:08.8
on a regular basis and what I like to do
with the simple green is go ahead and
7:08.8
7:15.1
squirt some down in there and then I use
a q-tip or a clean paper towel and I
7:15.1
7:22.5
gently remove anything that’s on that pH
probe now in the conductivity probe
7:22.5
7:27.0
you’ll notice that there’s a little
spoke that comes out halfway into it
7:27.0
7:31.9
that’s how it gets its charge from the
anode to the cathode we actually have a
7:31.9
7:37.3
nice small little brush that allows us
to clean the bottom and all around that
7:37.3
7:41.6
without bending it be careful you do not
want to bend that little spoke that
7:41.6
7:46.8
comes out of that probe cup so if you
have a controller at a customer account
7:46.8
7:52.9
and you need to clean that conductivity
probe my favorite way of doing that is
7:52.9
8:00.0
to isolate the flow on either side take
the probe out and then if you have some
8:00.0
8:05.2
shop air and you can dry the probe you
will be amazed at what you see on that
8:05.2
8:11.0
probe when it’s wet it looks clean but I
assure you when you dry that out it is
8:11.0
8:17.6
not clean at all and you might then see
oh that’s why I’m not getting a good
8:17.6
8:23.6
reading so if you want to use shop air
by all means do that but here’s what I
8:23.6
8:29.2
want you to do I want you to keep a
scotch brite pad in your test kit or in
8:29.2
8:34.2
your bag wherever you will want to store
it where you’re not going to use it for
8:34.2
8:40.4
anything else the issue when a lot of us
clean these probes is we use a shop rag
8:40.4
8:45.5
that we’ve used for the past 12 years
that has everything accumulated on it
8:45.5
8:50.2
within that 12 years folks don’t do that
you’re putting oils and all sorts of
8:50.2
8:55.8
stuff that you’ve cleaned up in
other areas on your probe make sure you
8:55.8
9:02.5
have a designated scotch-brite pad for
this purpose now on conductivity probes
9:02.5
9:07.2
the toroidal probes are a little
difficult to clean I have found a
9:07.2
9:11.6
toothbrush works pretty well to get in
there for those but the standard
9:11.6
9:16.9
conductivity probes will either have two
raised probes or they’ll be flush with
9:16.9
9:23.3
the surface you can use the scotch brite
on either one of these and with the
9:23.3
9:28.7
raised probe what you’re going to do is
put a drop of alkalinity titrant on both
9:28.7
9:33.6
of the electrodes and then you’re going
to use your scotch brite pad and you’re
9:33.6
9:39.4
going to clean on the top and all around
the sides of each of those you want to
9:39.4
9:44.8
make sure you’re using a different spot
on each one of the electrodes because
9:44.8
9:48.8
they’re charged differently and they
could attract each other once you’re
9:48.8
9:53.7
done doing that go ahead and use your
deionizing bottle and rinse it off
9:53.7
9:58.7
really well and then put a couple of
extra drops on both of the probes so
9:58.7
10:02.8
that way if you got anything on there
during the cleaning process that will
10:02.8
10:08.3
get that off and again that’s the
alkalinity titrant now if the probes are
10:08.3
10:15.5
flush to the surface when you’re swiping
back and forth you don’t want to put one
10:15.5
10:20.6
probe on to the other because again the
opposites attract so what you want to do
10:20.6
10:25.2
you want to do an up-and-down fashion
where you’re not over crossing each of
10:25.2
10:29.4
the probes I hope that makes sense I’m
trying to make visual motions but that’s
10:29.4
10:33.1
really hard to come through on the
podcast again once you’re done with that
10:33.1
10:38.1
go ahead and follow that up with your DI
water and then put a little bit more
10:38.1
10:43.4
acid on each one of the probes and then
rinse that off with DI water that then
10:43.4
10:50.2
leaves you with a very clean probe now
if you calibrate a probe and you did not
10:50.2
10:54.7
clean it folks you did not calibrate
that probe and when I talk to water
10:54.7
10:59.9
treaters out in the field they hardly
ever do that so please include this step
10:59.9
11:05.4
with what it is that you are doing now
let’s talk about the differ
11:05.4
11:10.7
juice that you can use in calibration
well depending on the meter it’s going
11:10.7
11:16.1
to ask you if you want a two point or a
three point calibration some well some
11:16.1
11:20.2
won’t
a two point calibration can be defined
11:20.2
11:26.2
as this the low point is absolutely no
conductivity at all so basically that
11:26.2
11:30.6
probe is being held in your hand and
it’s dry and it’s just out there in the
11:30.6
11:36.9
air the high conductivity is whatever
fluid that you’re putting it in and I
11:36.9
11:43.1
urge you to use standard with this
because that way you know for sure and
11:43.1
11:48.9
folks don’t think you can keep reusing
standard standard is a one-time use only
11:48.9
11:55.0
because whenever you put something in
there you are changing the value of that
11:55.0
12:00.6
standard standard is not that expensive
you are not going to bankrupt anybody by
12:00.6
12:05.9
using fresh standard each and every time
when it comes to standard we have
12:05.9
12:10.0
different types depending on what we’re
testing so we have pH standards we have
12:10.0
12:16.1
conductivity standards we have ORP
standards we have PTSA standards
12:16.1
12:21.5
depending on what the normal range is
that you’re testing that’s what you want
12:21.5
12:26.8
to buy that standard in now here’s a
little aside from that when it comes to
12:26.8
12:34.3
conductivity standard my favorite is the
1413 micro mol standard I will tell you
12:34.3
12:38.9
when I’ve had customers calibrate
equipment and I’ve given them 1000
12:38.9
12:45.5
conductivity standard anything between
800 and 1,200 is within range of that
12:45.5
12:54.7
1000 according to them however when you
give somebody a 1413 standard you better
12:54.7
13:01.8
believe that they are going to get that
on the money with 1413 conductivity now
13:01.8
13:09.9
you might be wondering 1413 that’s so
random why is there a 1413 standard it’s
13:09.9
13:13.8
actually Oh probably the easiest
standard to make what that is that’s a
13:13.8
13:19.0
molar solution of potassium chloride
into one li
13:19.0
13:23.8
of water and attention folks I’m getting
ready to do some chemistry but if you
13:23.8
13:30.2
look at the molecular weight of
potassium chloride chloride is 35.5 and
13:30.2
13:35.4
potassium is 39.1 if you add those
together that’s seventy four point six
13:35.4
13:42.8
so if you put point seven four six grams
of potassium chloride into one liter of
13:42.8
13:49.4
water and this is deionized water of
course your conductivity is going to be
13:49.4
13:52.8
1413 I don’t know if you’ve ever
wondered where that came from
13:52.8
13:58.5
but I know when I understand where
things get derived from I understand
13:58.5
14:02.7
them a lot better so there you go that’s
some free information from me to you and
14:02.7
14:07.6
then of course with pH standards folks
there are pH standards for just about
14:07.6
14:15.1
every pH you want out there but the most
common ones are pH 7 pH 4 and pH 10 but
14:15.1
14:21.4
again before you use any of these you
want to make sure that your batteries
14:21.4
14:27.0
are good your power source is good and
that everything is clean if you did not
14:27.0
14:32.5
do that don’t worry about calibrating
worry about changing your batteries and
14:32.5
14:37.8
cleaning the meter because there’s a
film that will occur and you’re not
14:37.8
14:42.0
getting a true reading like you think
you’re getting the reading of whatever
14:42.0
14:46.1
standard you have going through that
film well I mentioned the two point
14:46.1
14:51.2
calibration the 3 point calibration goes
through exactly those three standards
14:51.2
14:56.0
and typically you’ll see that in pH now
to get back to our 2 point calibration
14:56.0
15:00.1
typically what we’ll do is we’ll
calibrate it in the air and then we’ll
15:00.1
15:06.3
put it in that standard my preference is
that 1413 standard and some meters they
15:06.3
15:10.8
don’t have a low and high they just have
calibrate me to what I’m supposed to be
15:10.8
15:15.5
and then you would do that a little tip
is instead of immediately hitting the
15:15.5
15:20.8
calibration button once you zero that in
on whatever that standard number is let
15:20.8
15:26.0
it sit there for a couple of seconds and
just make sure that it is reading what
15:26.0
15:30.6
you think and then when it’s holding
steady then go ahead and
15:30.6
15:35.4
press that calibration button on pH a
lot of times we’ll have a two-point or a
15:35.4
15:41.4
three-point calibration and what that is
is typically we’re using seven standard
15:41.4
15:45.7
and then a four or a ten standard that’s
with the two-point with a three-point
15:45.7
15:52.0
we’re using all again after you have a
nice clean probe your battery is changed
15:52.0
15:56.8
out you’re gonna go ahead and most
meters start with seven again you don’t
15:56.8
16:01.5
want to keep reusing standard this is
brand new standard every time you use it
16:01.5
16:06.2
and you’re gonna put that seven in there
and you’re gonna calibrate the meter to
16:06.2
16:11.3
seven then a lot of meters will tell you
to put four in or they’ll tell you to
16:11.3
16:16.5
put 10 in or some will just know that if
you’re putting four or ten in so I like
16:16.5
16:23.4
to test the last solution on what I am
normally going to test so in cooling
16:23.4
16:28.2
tower water it’s normally in the eights
so I’ll normally end with ten I don’t
16:28.2
16:31.7
know if that’s right or wrong that’s
just how I do it so I’ll put the seven
16:31.7
16:35.8
in I’ll make sure that that’s holding
for a couple of seconds I’ll then hit
16:35.8
16:41.2
calibrate I will then hit the four
standard pour that in there and by the
16:41.2
16:47.5
way you want to make sure that you rinse
the old standard out well if I just pour
16:47.5
16:52.6
the seven out and then I fill my cup up
with four I do not have four in that cup
16:52.6
16:58.6
I have four with seven residual left
over so I actually triple rinse my cup
16:58.6
17:03.9
with that four standard then on the
fourth fill I know I’m getting a good
17:03.9
17:10.1
for pH reading I let that stabilize I
then hit the button and then I do the
17:10.1
17:15.4
same thing triple rinsing with the ten
and then on the fourth fill I will then
17:15.4
17:20.2
get my pH reading for 10 and I’ll
calibrate it and the meter should have a
17:20.2
17:26.9
nice stable calibration at that point
now let’s talk about what happens when
17:26.9
17:30.5
you calibrate a meter or a controller
and by the way you’re going to the exact
17:30.5
17:35.2
same thing with a controller that I just
mentioned for the handheld meter when
17:35.2
17:41.7
you calibrate a probe and say no probe
the answer that you’re giving me is not
17:41.7
17:48.2
correct it really should be
you are adding some sort of number to
17:48.2
17:53.5
the algorithm that that probe is reading
every time you calibrate you’re adding a
17:53.5
18:00.1
new number to that so on top of on top
of on top of folks if you have not reset
18:00.1
18:04.9
that value and a lot of times you have
to do that by factory reinitializing the
18:04.9
18:10.8
controller or the meter you might not be
getting an accurate reading because
18:10.8
18:15.2
there’s so many values that are in there
that you’ve previously calibrated on
18:15.2
18:20.5
you’re not getting the reading that you
think and your meter is just off because
18:20.5
18:25.3
there’s so many equations in there now
something that’s very important that if
18:25.3
18:30.2
you ever change your probe out whether
it’s a controller whether it’s a
18:30.2
18:36.7
handheld meter you have to set that back
to zero because those old numbers were
18:36.7
18:42.7
based on your old probe and again even
if it’s the same probe and you haven’t
18:42.7
18:47.6
done that in a while it’s not a bad idea
to go ahead and start from scratch
18:47.6
18:54.0
because now you know that that
calibration is based on the base reading
18:54.0
18:59.7
of that probe if you have a controller
and you have to factory reinitialize
18:59.7
19:03.7
that and I have seen more and more
controllers that will allow you to reset
19:03.7
19:07.7
just the calibration on a particular
probe but there are still some
19:07.7
19:12.6
controllers out there that won’t allow
you to do that so what you have to do is
19:12.6
19:19.5
go in and factory reset that a lot of
the controllers will have a USB drive
19:19.5
19:25.3
port on there where you can go ahead and
capture your program so that way you
19:25.3
19:29.5
don’t have to reprogram everything if
you don’t have that we’ll go ahead
19:29.5
19:34.2
before you factory reinitialize it take
a legal pad whatever you’re using to
19:34.2
19:39.9
take notes and make notes of what all of
your items are in the entire controller
19:39.9
19:46.2
programming so you can program that back
in I know that’s a lot of work but you
19:46.2
19:51.0
really don’t know what that probe is
reading until you do that folks it’s
19:51.0
19:54.9
really important whenever you’re
handling the probe these things are made
19:54.9
20:00.4
out of glass or a very thin
piece of metal you have to make sure
20:00.4
20:05.5
that you don’t damage those in cleaning
I’ve seen many people shove a paper
20:05.5
20:11.2
towel down a reservoir or Cup where the
probe is and they’ve been things and
20:11.2
20:15.6
then things never work right so please
be careful when you’re doing this
20:15.6
20:22.7
process and like I said before if you
keep your equipment clean you will get
20:22.7
20:27.8
so much better results from that
equipment and folks I gotta let you know
20:27.8
20:32.6
I’ve said this on other shows but you
are only as good as the equipment that
20:32.6
20:38.8
you are using and your equipment is only
as good as the person that is using that
20:38.8
20:44.5
piece of equipment so if you have not
gotten out the OEM the original
20:44.5
20:50.7
equipment manual for your particular
piece of equipment please go online and
20:50.7
20:55.2
download that and see what they say
about calibrating see what they say
20:55.2
21:00.5
about troubleshooting and that’s gonna
get you more in the know about what’s
21:00.5
21:04.9
going on each and every time you
calibrate your equipment another
21:04.9
21:11.2
question I get on a fairly common basis
is can you bring a failing probe back to
21:11.2
21:15.4
life and a lot of people say you can
rehydrate those so a lot of the probes
21:15.4
21:18.8
they’ll have that potassium chloride in
it that we talked about so if you have a
21:18.8
21:24.6
supersaturated solution a potassium
chloride and you put that probe in there
21:24.6
21:29.2
well that glass is a semipermeable
membrane and that’s actually how that
21:29.2
21:32.9
works so since you have a higher
concentration on the outside of
21:32.9
21:36.4
potassium chloride sometimes it will
migrate through to where there’s a lower
21:36.4
21:41.0
concentration and you might be able to
get a little bit more life out of that
21:41.0
21:46.7
probe but folks I’m here to tell you
I’ve never had that work more than a
21:46.7
21:50.7
couple of weeks I got really excited hey
I saved a hundred-and-something bucks
21:50.7
21:55.2
for this new probe I was able to
rehydrate it back in my lab but when I
21:55.2
22:00.8
went back out there in the field it just
did not hold calibration so when you buy
22:00.8
22:08.3
any type of probe make sure you budget
for replacing that in about a year’s
22:08.3
22:12.5
plus time because again as
said at the top of the show when these
22:12.5
22:18.7
things are made they already start dying
so I hope this gets some of the
22:18.7
22:24.1
questions answered that I’ve received
about calibration about pH probes and
22:24.1
22:29.9
conductivity probes we didn’t talk a lot
about PTSA probes or ORP probes but just
22:29.9
22:34.5
know that they have standards for that
the exact same thing that I was saying
22:34.5
22:39.2
earlier applies for those make sure that
they are clean make sure your power
22:39.2
22:44.0
source is good you might have to reset
any former calibrations that you have
22:44.0
22:49.0
done then you’re going to put those into
a standard and folks they make all sorts
22:49.0
22:55.4
of different types of standards PTSA is
one that we make here in the lab we just
22:55.4
22:59.9
take the PTSA that we’re blending our
products with and then we calibrate to a
22:59.9
23:05.3
hundred parts per billion and we go
ahead and make sure that that lens is
23:05.3
23:11.3
nice and clean the same way I told you
that we cleaned the pH probes is the
23:11.3
23:15.2
same way that we clean that little lens
that sends the ultraviolet light through
23:15.2
23:20.2
and the other side that reads it and
we’ve had really good success because I
23:20.2
23:26.5
think we keep the battery nice and fresh
and we rinse with deionized water after
23:26.5
23:32.7
every single test and then of course we
clean it on a regular basis folks that’s
23:32.7
23:37.3
something that you might want to
consider is to keep a log on how often
23:37.3
23:44.3
you clean it so every single week what
my team does is they calibrate their
23:44.3
23:49.7
meters and they log those and they make
sure that they log that we are cleaning
23:49.7
23:53.7
it and that’s not because I don’t trust
that they’re not doing that but it’s
23:53.7
23:59.8
just a thing that allows us to keep
doing it on a consistent basis and then
23:59.8
24:05.6
we can see if a probe is actually
getting out of calibration so it’s not
24:05.6
24:10.0
quite time to change it but we can see
we need to get another probe in here
24:10.0
24:15.1
because this one’s going to need to be
changed soon and folks that being said
24:15.1
24:22.6
you don’t want to stock pH probes or ORP
probes things that have that glass cell
24:22.6
24:26.1
because again they’re going
to die on the shelf so you want to order
24:26.1
24:32.4
those when you need those and then of
course you might not have time to go and
24:32.4
24:35.7
order those so maybe you want to keep
one on the shelf but I don’t like to do
24:35.7
24:39.8
that I like to order them as fresh as
possible because they have a very
24:39.8
24:45.0
limited shelf life so folks something
you might want to consider is that log
24:45.0
24:51.2
that just makes sure that you’re doing
something on a regular basis and you can
24:51.2
24:55.1
do that with all of your tests something
that I really like to do here at
24:55.1
24:59.7
Blackmore Enterprises is I will make a
known concentration of something up in
24:59.7
25:05.9
my lab and then I’ll have everybody out
on our team come in and they will run
25:05.9
25:11.7
those tests mathematically I know what
they should get but now we’re gonna see
25:11.7
25:16.7
what they get in their test kit and if
it’s off normally it’s not a procedural
25:16.7
25:20.8
issue but sometimes it is and then we
can educate based on that but normally
25:20.8
25:26.1
it’s because maybe one of the dropper
tips is clogged up maybe there is a
25:26.1
25:31.0
malfunction with their digital Thai
trader because we have a procedure like
25:31.0
25:38.2
that we are able to isolate issues
before they become an issue
25:38.2
25:45.5
so again are you treating your equipment
the way that you should be treating it
25:45.5
25:51.2
because US water treatment folk are only
as good as the equipment that allows us
25:51.2
25:57.4
to get a small glimpse inside the water
and if we are not treating that
25:57.4
26:02.3
equipment properly it’s not going to
give us good results meaning that we are
26:02.3
26:08.6
not going to do what we should do in
adjusting that program folks this entire
26:08.6
26:15.3
episode came from questions from the
Scaling UP nation around calibration of
26:15.3
26:22.7
pH ORP and conductivity so I hope this
was helpful I hope you are now thinking
26:22.7
26:26.3
when was the last time I changed the
batteries you know I really do need to
26:26.3
26:34.0
clean my meter on a more regular basis
and maybe I do need to refer to the
26:34.0
26:37.6
owner’s manual to make sure that I’m
doing all
26:37.6
26:42.5
of that properly folks you can find all
of that online about your meter and I
26:42.5
26:47.4
want to urge you to keep those questions
coming it’s because of those questions
26:47.4
26:51.9
that I was able to do this show so thank
you for everybody out there in the
26:51.9
26:57.2
Scaling UP nation that wrote in and
asked me about that and I hope that this
26:57.2
27:03.0
episode has helped make your tests a
little bit more accurate have a great
27:03.0
27:08.0
week folks
