6.2 ORP – mV Calibration
This mode allows one-point calibration.
1) Enter Calibration mode . While in Measurement
mode, push the CAL key. Press the ENTER key .
The upper and lower display reads “CAL OrP”.
Note: If the upper and lower display read “CAL PH”,
see section 7.4 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 adjust the mV value to that of the standard
solution.
5) To confirm, press the ENTER key . The controller calculates the
correction factor and returns to the Measurement mode.
