7.4 Edit Sensor Calibration Constants
Enter Calibration mode as described in section 7.1 and select Edit.
All calibration constants of the primary measurement (p) for the sensor are displayed on Line 3.
All calibration constants of the secondary measurement (s) for the sensor are displayed on
Line 4. For conductivity and resistivity sensors, the (p) primary measurement is conductivity or
resistivity and the (s) secondary measurement is temperature.
The calibration constants can be changed in this menu.
Select Yes to save the new calibration values and the successful Calibration is confirmed on the
display.

NOTE: Each time a new sensor is connected to the M300 transmitter, it is necessary to enter the
unique calibration constant located on the sensor cable.
7.5 Sensor Verification
Enter Calibration mode as described in section 7.1. and select Verify.
The measured resistance of the primary (Conductivity or Resistivity) measurement and the
secondary (Temperature) measurement are shown. The meter calibration factors are used when
calculating these values.
Dual channel transmitters use the or key to toggle between Channel A and B.
