Orp Probe?

[drillsar]

I just got my Orp Probe and I went to setup and on mistake I hit calibrate and I hit select and it said probe defective did I mess up the ORP Probe? Do I have to know get calibration fluid?

First see if it works (it will take a week or more to stabilize). You're probably fine.

You can always initialize the memory after making backups of course. That will wipe out any stored calibrations for probes (including your pH probe).

Anyway, it takes more than just fluid to calibrate those things. You need quinhydrone.

You can email Neptune and they might be able to purge the calibration settings.
