ACjr problems

[skjohn98]

I just hooked up a new PH probe to the JR, I tried 10, 7 and 4 calibration fluids and each time it gave me a faulty probe reading.

I then hooked up the probe to a pin point meter and it calibrated ok and have it in my sump

Another problem I am having with the JR is I am losing time on it all the time, every few days I have to reset the time some most of the times its just a few hours but it shouldnt be doing this any ideas?

The jr is about a year old if that

The ACjr have a leap second feature (I think that's what they call it) to allow you to speed up the clock. I have mine set at >100 seconds per day and it still falls behind. Apparently, they all do this.

I don't know what to tell you about your probe. It the old probe worked on the ACjr and the new probe works on the Pin Point, it should work on the ACjr. pH probes typically have a common connector. You might just check the connection and try again. Not much help, but it's worth a try.
