8) Press the ENTER key. If you entered the calibration mode using the CAL key, the

controller will return to the Measurement mode. If you entered the calibration mode from the

Advanced Set-up mode, the controller will return to the sub-function menu.

Note: If there is a calibration error, the controller displays “ERR”. If this happens, press both the ▲

and ▼ keys (escape) to restart the calibration beginning from step 1.

Note: When calibrating with manual temperature compensation, the controller automatically

changes from the preset process temperature to the calibration temperature. After leaving the

Calibration mode, the controller switches back to process temperature (for setting the calibration

temperature and the process temperature, see section 7.2.3).

6.2 ORP – mV Calibration

This mode allows one-point calibration.

1) Enter Calibration mode. While in the

Measurement mode, press the CAL key and

scroll to Calibration code “11”. Press the

ENTER key again. The upper and lower display

reads “CAL OrP”.

NOTE: If the display reads “CAL pH”, see section

7.6.2 for procedures on how to switch from pH to

ORP mV readings.

2) Place sensor in the ORP solution.

3) Press the ENTER key to begin calibration. The

“CAL” indicator appears on the display. The

upper display shows the current mV output of

the electrode without any offset adjustment.

4) Press the ▲ and ▼ keys to match the mV

value to your exact reading.

5) To confirm, press the ENTER key. The

controller calculates the correction factor and

returns to the Measurement mode.
