Calibration Mode

You can reach the Calibration mode directly from the Measurement mode by pressing the CAL key and
entering the Calibration security code. You can also reach the Calibration mode from the Advanced
Setup mode.

Conductivity Calibration

Calibration is always carried out in the specific range selected. The Conductivity Controller allows a
one-point calibration.

Note: If there is a calibration error, the controller displays "ERR". If this happens, push both the
and keys (escape) to restart the calibration beginning from step 1.
Note: When calibrating with manual temperature compensation, the controller automatically changes
from the preset process temperature to the calibration temperature. After leaving the Calibration mode,
the controller switches back to process temperature (for setting the calibration temperature and the
process temperature, see section 7.4.3).
