Calibration error.  
Buffer value does not 
match displayed value or 
electrode is disconnected 
or failing. 

Use fresh buffer solutions.  
Check electrode connection. 
Clean & recondition electrode. 
Replace electrode. 

Broken or worn electrode 

Replace electrode 

Unstable pH 
reading 

External ‘noises’ or 
induction (electrical ‘noise’ 
caused by a nearby motor) 

Remove or switch off interfering 
device 

Slow 
response 

Dirty electrode. 

Clean & rehydrate the electrode 

CAL

 

during pH 
CAL mode 

Calibration was attempted 
using only 1-point that was 
not pH 7 (USA) or pH 6.86 
(NIST). 

Recalibrate using 2 or more pH 
points or use pH 7 (USA) 
or use pH 6.86 (NIST).
