Meter error shown:
•
Conductivity Out of Range, TDS Out of Range,
Salinity Out of Range, Temperature Out of Range:
o
Ensure electrode is connected to meter
o
Check that electrode does not have any
damage or cracks
o
Ensure the electrode is properly immersed
in the sample solution, with the electrode
sensing plates and temperature sensor
submerged below the top of the sample
solution
o
Verify cables do not have any damage
o
Perform a factor reset on the meter
6.2 Measurement
Troubleshooting
Reading is unstable, slow to stabilize
•
Clean electrode to remove build-up or
contaminants, 0.1M HCl is recommended and
adding pepsin is helpful if protein build-up occurs
•
Check electrode for damage, cracks or breaks
•
Check cables for damage or breaks
•
Remove any interfering devices from area
•
Replace old electrode with new electrode
• If sample temperature is changing, allow
temperature to stabilize
Reading freezes on display
•
Check meter Read Type setting
o
If meter Read Type is set to Auto-Read,
press the “Measure” key to start a new
measurement
• Check electrode for damage, cracks or breaks
•
Check cables for damage or breaks
