Manual Calibration

(Calibration with manual specification of the number of calibration points and
the buffer solution)
1) Select the number of calibration points and press the Start softkey.
2) Adjust the temperature-corrected value (see buffer table) for the 1st/2nd/3rd
buffer solution and press Continue (repeat this step for each calibration point).
Note: When using sensors without temperature detector, you should adjust the
temperature manually before starting calibration (see page 31).
3) Finally, the calibration data will be displayed.
You can Apply or Discard these values.

Data Entry Calibration

(Calibration by entering known sensor values)
1) Press the Start softkey.
2) Enter the known sensor values for zero and slope.
3) Finally, you can Apply these values or Cancel the calibration.
pH ORP

Calibrating a pH/ORP Combo Sensor

The pH/ORP combo sensor can be calibrated as a pH sensor
and/or as an ORP sensor.
pH Calibration
Follow the instructions given for pH calibration, page 23.
ORP Calibration
Follow the instructions given for ORP calibration, page 25.
Note: To abort calibration, you can press meas at any time.
