After the calibration the Multiplier or slope calibration factor ”M” and the Adder or offset calibra-

tion factor ”A” are displayed.

Select Yes to save the calibration values and the Successful Calibration is confirmed on the dis-

play. If an ISM sensor is connected, the calibration data will be stored in the sensor.

You will get the message ”Re-install sensor” and ”Press Enter” on the display. After pressing

”Enter” the M300 returns to the measuring mode.

7.2.3 ProcessCalibration

Enter Conductivity Sensor Calibration mode as described in section 7.1 “Enter Calibration Mode”

and choose one of the compensation modes (see section 7.2 “Conductivity/Resistivity Calibra-

tion”).

Select Process Calibration and press [ENTER]. With conductitivty sensors a process calibration

is always performed as a slope calibraton.

Take a sample and press the [ENTER] key again to store the current measuring value.

During the ongoing calibration process, the letter of the channel, which is concerned by the cali-

bration, ”A” or “B” is blinking in the display.

After determining the conductivity value of the sample, press the [CAL] key again to proceed

with the calibration.

Enter the conductivity value of the sample, then press the [ENTER] key to start the calculation of

calibration results.

After the calibration the Multiplier or slope calibration factor ”M” and the Adder or offset calibra-

tion factor ”A” are displayed.

Select Yes to save the calibration values and the Successful Calibration is confirmed on the dis-

play.
