* Conductivity meter does not require calibration using standard solution as routine maintenance if the
correct cell constant has been defined upon start-up.
* For details on the calibration using standard solution, refer to Section 6.5 of the SC100 Panel Mount

Dry the electrode in zero (air)
calibration.
When error message
C-1 appears, bring the
standard solution within
the operating temperature.
* Correct temperature
coefficient should be set when error message C-4 appears.
If an E-4 error message
appears, the converter has malfunctioned.
Contact your sales representative or the nearest service office.
