Hi all,

I have two Redox probes, one on P4 on the Redox / PH socket ( Redox first means that is the probe connection for redox)

Other one on the Expansion box 1.

Probea are working tested both on a Aquamedic Redox controller.

When I calibrate - null plug then 220v solution I always get an incorrect reading on both devices.

The ACD on null plug goes between 468/9 when I attach the Redox probe ACD is almost the same 468/450.

The probe just reads all over the place keeps creating upwards till I reach 1000mv then stops.

This is happening on both EB1 firmware 1.08 and P4 firmware 7.14.
Any help?
