Problems
Solutions
Device is not accurate
Make sure that pump #1 and pump #2 are correctly
calibrated, and that there is no air (long air gaps) inside the
silicone tubing. Small air bubbles inside the tubing don’t
impact measurement accuracy.
Make sure that the magnetic stirring bar/pellet for mixing
tests fluid is inside kHLab cylindrical test chamber per the
instructions.
Make sure that silicone tubing supplying reagent and test
water are submerged below reagent solution and aquarium
water levels.
Make sure that the
green
tip under the kHLab module
chamber cover is submerged below test water level when
alkalinity test is in progress.
When replacing dosing pumps PharMed tubing, the device
may initially perform slightly different from before tubing
replacement but should go back to the same accuracy
after a few days without any problem. During that time
next pump calibration is
not
recommended. New pump
calibration is required when the new tubing has different
diameter than previous, original one or has different nominal
flow, i.e. tubing from a manufacturer other than Pacific Sun.
Problem with
communication between
the dosing station and
application
Make sure that the dosing station is connected to your PC/
Laptop through Wi-Fi network:
