Frequently Asked Questions
 What is
the dynamic test range for the TruTest?
 Free Chlorine/ Bromine: 0-15ppm
pH: 6.1-8.8
Total Alkalinity: 0-300ppm
An error message will be displayed when testing
water samples outside of these calibrated test ranges.
What can I expect for the precision of the test
parameters?
The precision of the unit is as the following:
Free Chlorine/Bromine: 0-1ppm range
+/- 0.3ppm : 3-10ppm range +/- 1ppm
pH: +/- 0.1pH
TA: +/-30ppm
As with any test, technique consistency will
improve precision results.
How long will the batteries last?
The AA batteries should last an entire pool
season’s worth of testing. The display window will flash
“LO” if the batteries are below a certain level of power needed
to perform a test.
How long will the unit last?
With good cleaning and storage habits, the meter
should last longer than 3 years.
Why does the unit sometimes not appear to stay “ON”?
The “on” button if depressed quickly on and off
can cause conflicts with the software, appearing to not “stay on
(or off)”. Simply waiting a minute or so before pressing
the ON button should help clear the cycle.
How should I be cleaning my TruTest?
A simple, non-abrasive wiping of the test strip
window and all other surfaces with clean, fresh water should
clear any residual chemicals remaining after testing.
What will happen if the meter falls into the pool/spa?
The meter was designed to withstand this kind of
accidental submersion and should float upon entry into the
water. Simply remove the meter, take out the batteries
from the battery compartment, dry the battery compartment
thoroughly and replace with dry batteries. The meter
should return to full performance.
Should I “place” or “slide” the test strip onto the
test strip window?
It is very important that you do not slide the
test strip on the window. This action will result in
inaccurate readings. A simple method is to place the first
pad nearest the top of the strip onto the window first, then
lower the rest of the strip down onto the window. This
will ensure that the strip is all the way in and down onto the
window.
