6. Troubleshooting
(3) Err3 Calibration error
Cause:
When the calibration with standard solution is made, each time cell constants are
changed. Err3 occurs if the conductivity of the standard solution is wrong, or changed
cell constants are beyond
؎ 20% of the standard cell constant, due to a damaged sensor.
Corrective action:
* Use correct standard solution conductivity. (Refer to Sec. 5.4)
* Replace the sensor. (Refer to Sec. 1.6)
(4) Err6 Meter electronics failure
Cause:
Err6 occurs if the meter electronics fails.
Corrective action:
* Contact your nearest Yokogawa sales office.
(5) or Out of measurement range
Cause:
Conductivity is over the maximum value on the range.
Corrective action:
For manual ranging, select an appropriate range. If value exceeds maximum of highest
range (or when on autorange), use a more appropriate sensor (see Sec. 4.3 (3)).
