The CALIBRATE submenu appears.
2. Place the sensor in a standard solution of known conductivity and allow the
measurement reading to become relatively stable.
3. Press ENTER to access the CAL segment with the flashing prompt.
4. Use the IRC editing keys to enter the conductivity value of the standard solution.
Press
ENTER .
5. Press EXIT to return to the main display.
7.3.3 Zeroing the sensor
1. Press CAL and then NEXT to enter the SENSOR 0 menu.
2. Press ENTER to access the SENSOR 0 submenu.

7.3.4 Adjusting the temperature
1. Press CAL and then NEXT until you see TEMP.
2. Press ENTER .
The TEMP submenu appears.
3. Place the sensor in any solution of known temperature. Allow the temperature of
the sensor to become relatively stable.
4. Use the editing keys of the IRC to change the values as needed.
5. Press ENTER to standardize the temperature reading and return to the TEMP ADJ
screen.
6. Press EXIT to return to the main display.
7.3.5 In-process calibration
1. Press CAL and then NEXT three times to access MTR CAL.
2. Use the IRC to go through the on-screen prompts.
3. Press EXIT to return to the main display.
7.3.6 Temperature slope
1. From the CAL menu, press NEXT until TEMP SLOPE is shown.
2. Use the IRC arrow keys to enter the slope. Press ENTER to register the slope in the
memory of the transmitter. Press EXIT to return to the main screen.
3. If the temperature slope of the process is not known, then refer to the below guide:
