Comparing the value of two probes

[pintomollo]

Hi there !

I have two conductivity probes that I would like to compare in my code to detect potential out-of-calibration issues (i.e. if one needs to be recalibrated, it should not read the same as the still calibrated one). That's the context, however my question is more general than this. I would like to know if there is a way to compare two probes programmatically ? E.g.:
If Probe1 < Probe2 Then ON

In my particular case, what I would like to do is the following:
If Probe1 < Probe2+-5.0 Then ON
If Probe1 > Probe2+5.0 Then ON

To check that they stay in a 5 ppt value range.

I have read the documentation and believe this is not yet possible to implement, but I'd be happily proven wrong. Yes, I tried to run this exact code as well as variants of it and it doesn't work

Cheers.

Unfortunately you can't do numeric comparisons or math. The best you can do is alarm or react when either goes out of range or both go out of range (depends on whether you want reliability or security).

That's also what I thought. Thanks a lot for the confirmation. Hopefully that will become available in some future release.
