POSSIBLE SOLUTION
• Completely submerge the
probe.
• Allow sufficient time for the
electrode and Temp probe
stabilization.
• Recalibrate with correct value
for the conductivity standard.
• Replace conductivity standard.
• Clean cell.
• Return for service.
• Decrease/Increase the sample
temperature.
• Return for service.
