9) Calibrate of probes
With the following steps, you will have calibrated the electrodes in no time:
There are 2 ways to calibrate:
Method 1: Calibration via calibration fluid
1. Immerse the measuring heads in the calibration fluids for pH (pH 7) and ORP (465-468
mV) and wait 5 minutes to reach equilibrium before proceeding with the calibration
procedure.
Press the pH and ORP buttons (top and bottom buttons)
separately for 10 seconds (top and bottom buttons)
As soon as the calibration starts, a screen is activated that shows what you are
calibrating. You can calibrate only Ph or rx only or both at the same time
