I just hooked up my ORP probe and started to calibrate it before reading the manual. Wouldnt you just know it... Once I started to calibrate the probe, I realized I needed some calibration solutions and there didnt appear any way to back out of the program. What do I do now? It reads 200 after 3 days since being placed in the sump.
Thanks,
Jeff
