ORP probe faulty?

[butcherman]

My ORP reads find on any reading below 325. at 325 it changes to 0 when ORP drops to below 325 it starts shoing reading again.

Im using 1.0.2 libraries and modified the libraries to calibrate with 220mv fluid.

when i recalibrate the terminator that came with the probe registers 1695
and the 220mv fluid reads 595

Is this the probe, hardaware or the code?

Has it worked in the past?

Yes worked fine previously.

1695 with the terminator sounds ok, but 595 for 220mV is too low.

Probably best to replace
