15 TROUBLESHOOTING & ERROR MESSAGES
TROUBLESHOOTING
Problem Possible Cause Solution
Power ON but no display AC adapter not connected properly Connect AC adapter properly
Unstable Reading Electrode submersion in sample is
insufficient
Place electrode deeper into sample
Broken electrode Replace electrode
External noise causing instability in
reading.
Remove or switch off interfering motor
Dirty electrode Clean Electrode. Reactivate if necessary
Slow response Dirty electrode Clean Electrode. Reactivate if necessary
