Enter the value for Point 1 including a decimal point and units. The value in the second text line

is the value being measured by the transmitter and sensor in the units selected by the user.

Press [ENTER] when this value is stable to perform the calibration.

After the calibration the cell multiplier or slope calibration factor ”M” i.e. cell constant and the

Adder or offset calibration factor ”A” are displayed.

In case of a successful calibration, the calibration values are stored in the cal history* and taken

over (Adjust), stored in the cal history* and not taken over (Calibrate) or discarded (Abort).

* only available with ISM sensor. The values will be stored in the sensor.

If ”Adjust” or ”Calibrate” are chosen, the message ”Calibration successful” is displayed. In any

case you will get the message ”Re-install sensor” and ”Press ENTER” on the display. After press-

ing ”ENTER” the M400 returns to the measuring mode.

7.2.2 Two-point sensor calibration

(four electrode sensors only)

(Display reflects typical Conductivity sensor 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 calibration for two

or four electrode sensors”).

Select 2 point calibration and press [ENTER].

Place the electrode into the first reference solution.

CAUTION: Rinse sensors with a high-purity water solution between calibration points to prevent

contamination of the reference solutions.

Enter the value for Point 1 including a decimal point and units. The value in the second text line

is the value being measured by the transmitter and sensor in the units selected by the user.

Press [ENTER] when this value is stable and place the electrode into the second reference

solution.

Enter the value for Point 2 including a decimal point and units. The value in the second text line

is the value being measured by the transmitter and sensor in the units selected by the user.

Press [ENTER] when this value is stable to perform the calibration.

After the calibration of the cell multiplier or slope calibration factor ”M” i.e. cell constant and the

adder or offset calibration factor ”A” are displayed.
