Alkatronic hardware checklist for bad readings
1) Check the waste Hose (left hose on the holder) is all the way down in the beaker so all the water is taken out
2) Check the PH probe is above the magnetic stirrer (approx. 15mm from bottom of beaker)
3) Check the Pink tip of the regent line(centre hose on holder) is not blocked
4) Check all lines a clean and not full of detritus from the sump (See Tips and tricks Filter hose placement)
5) Check the internal pump hoses and hose replacement counter under setting if passed 800 replace internal hoses.
6) Check you did not use the Testing Beaker to do a calibration?
7) Check if you have broken you glass measuring vials and have replaced them with cheap Plastic Ones, it recommended
to check they are accurate before use. (Some of these have been known to be off by up to 3-5 mil)
8) Check you followed the Calibration process correctly. Alkatronic Quick Guide Pump Calibration. Alkatronic Quick Guide to calibrate the pH electrode
