Calibrate redox

[max@star.srl]

Good evening I'd like to know how to calibrate the redox probe, as I don't understand how to calibrate the first pass.

Hello,

The redox probe calibration requires you to use the null plug that comes with the ProfiLux controller.
Steps for calibrating can be found on page 57 of the ProfiLux 4 Resource Guide:
