3.5 ORP calibration
1) Attach the ORP electrode (optional, ORP-14) by connecting the
ORP electrode to the meter.
2) Power on the meter, and set the mode and function to “mV“
(refer to chapter 3.3, Page 9).
3) Immerse the sensing head of the ORP electrode in the ORP
standard buffer solution. The upper display will show the ORP
value in mV.
4) Press the “REC” button and “HOLD” button at the same time.
The display will show the following screen as an example. Now
release.
5) Use “ ” button, “ ” button to adjust the upper display value to
exactly match the ORP buffer solution value. Press the “Enter”
button twice to save the calibration data and finish the calibra-
tion procedure.
• ORP calibration is only possible if the ORP buffer solution
value is > 100 mV.
• ORP calibration at less than 100 mV is not permitted.
