Reef keeper sl2

[traxter]

Okay I have this setup
Rkl
Power bar
Sl2
Used ph probe of unknown condition
Just bought lab grad ph probe


Either probe I try comes back with a constant -2001 reaxing through the calibration process regardless of ph7, ph10, or R.O. being in contact with it.

I already updated the rkm-sl2 with the latest firmware (the head unit wouldn't recognize it until I did) other than that I'm not sure what's wrong.

Path followed was
Modules
Sl2
Ph
Calibrate

Any thoughts or help would be appreciated
