Im pretty sure im hitting ok, it looks highlighted, unless cancel is default, but ive tried both. I modified the pde, but also did the mem settings in RAGen

well it was still off but after messing around with the numbers a bit I got it to read the tank and the 10.0 solution correctly , but 7.0 reads at 7.3

ended up with 502 and 817

is it a concern that its not saving the calibration in mem?

ok, tried to recalibrate, before seeing this, after I loaded a new memory file, as I wanted to make some changes, readings came in as follows, 7.0 - 537 10 - 825, then hit ok, and unpluged the controller, and plugged back in, same thing. loaded your above code, same version 550 840 7.0 - 529 10 - 81...

ok, loaded code heres what I see/got 1st line is library version V0.8.5.16 2nd line is pH 7.0 calibrated reading (should be 502, according to numbers above) 550 3rd line is pH 10.0 calibrated reading (should be 827, according to numbers above) 846 4th line is actual reading. If you place the probe b...

Its a RAGen code, it also shipped with the new optiboot bootloader, if that makes any difference

Tom

6.8 and 9.7 respectively, the 3rd number bounces around alot

Tom

OK, home....third shifter, re- did the calibration, power cycled, same results. for the calibration screen numbers 7.0 - 502 10 - 827 I tested these standards which were brand new and sealed the first time I calibrated, against my handheld again, for kicks and they were dead on. right now the handhe...

updated see below

Yes, unplugged it, plugged it back in....no difference....I will try it again to be sure.

HI, I have a hand held PH reader that tests spot on with the calibration solutions, so I know that the reading from the PH probe on the RA is off, I calibrated as stated about, allowing 7-10 min for stabilization and after power cycling it still reads off, a little better but only about .1 higher, i...
