It can be noted that as with any test, technique consistency will improve precision results. Q: What is the dynamic test range for the TruTest?
• FC, 0-15ppm • pH, 6.1-8.8 • TA, 0-300ppm It should be noted that the Er messages will be displayed when testing pool samples outside of these calibrated test ranges (reference in the manual). Q: Can I compare the TruTest results to other test methods? A: The accuracy of the unit should only be compared to visual test methods. This is because the unit is capable of reporting numerical results between colorblocks and therefore the unit can be considered to be more accurate than a visual colorimetric evaluation (involving both human interpretation and interpolation). Digital readout in place of color interpretation is TruTests main benefit resonating with many pool/spa owners. Q: How long will the batteries last? How long will the unit last? A: The AA batteries should last an entire pool seasons worth of testing. The display window will flash LO if the batteries are below a certain level of power needed to perform a test. The unit has been developed for the consumers pool environment. W
