Explanation & Recommended Action
Temperature outside specified range.
Replace probe if necessary.
During conductivity calibration, the temperature is under/over the
conductivity calibration solution compensation limit.
Outside range in the corresponding scale.
Ensure the vent holes are completely submerged and the sample is within
specified range.
The meter fails to calibrate or gives faulty readings.
Replace the probe.
Displayed when the measured value is outside calibration range.
Contact the Hanna technical support for the periodic factory calibration.
