ProMinent DULCOMETER D1C Type D Operating Instructions Manual page 15

Complete Operating Menu / Description
Calibration of zero point (zp)
cali. zero point ?
PAR1
To determine the precise zero point (zp) of the sensor, hold the sensor in the air and select the second
menu option. The DULCOMETER
Enter when the value is constant.
The setting menu is inactive when "PAR2" appears.
During the calibration, the metering is reduced to the set basic load and control stops. The limit value
monitor and the fault diagnosis system are reset. The standard signal of the "measured value" output is
frozen.
Cell constant calibration (cc)
calibration cc ?
PAR1
To determine the precise cell constant (cc) of the sensor, place the sensor in a calibration solution
(sample 1) with a known conductivity and select the second menu option. The DULCOMETER
displays the conductivity which it has calculated with the current parameters. Press Enter when the value
is constant.
Select the next menu option and enter the conductivity of the calibration solution (arrow keys). Press Enter.
The D1C displays the recalculated cell constant and saves the value.
The setting menu is inactive when "PAR2" appears.
During the calibration, the metering is reduced to the set basic load and control stops. The limit value
monitor and the fault diagnosis system are reset. The standard signal of the "measured value" output is
frozen.
