reset back to factory specs?

[pdfrogman]

I bought a used AC3

the ORP probe was way off from my Milwaukee so I attempted to recalibrate it using just the pinpoint ph correction fluid now it stays at 254 and doesn't move is there a way to reset the controller back to factory specs?
I thought the probe was bad still didn't move after I replaced the probe

I also need to reprogram the controller so it might be easier to start from scratch

Thanks!

Just go through the ORP probe calibration, and leave the probe in the same solution for both the high and low cal points. The controller will say that the probe is defective and revert to the factory default calibration constants.

Also with setup->init memory you can revert back to the factory defaults on every setting.

I did that and got the message the probe was defective.
I replaced the probe when I got the controller it's stuck 254 MV

If you have a very old version of the firmware in the controller (3.0 or 3.1 I believe), update to the latest as there was a bug related to the ORP reading.
