“Calibration mV” menu.

ORP calibration procedure involves one calibration point and it requires a buffer solution. Default buffer solution should

be near working value. From “Probe” menu choose “Calibration mV”.

In the following example instrument will calibrate ORP using default buffer solutions values.

Note: this procedure assumes that instrument is correctly configured and a working ORP probe connected.

Otherwise unattended results may occurr.
