(b) Using a PT1000 (not sure that's relevant), with 1.7.0e the display reads "-DispNan-" ... graphing is fine, so the value is actually read ok. Haven't tried this in the older firmware.
This is strange. I connected a 1 kΩ resistor and got the measurements.
That's bizarre ... I've just attached a 1k resistor, using 4W resistance mode it's fine .. I switched to temperature and 4RTD and it said '-DispNAN-', then I went through some of the other transducer devices and it's started working ... very weird.
Just tried a reset and still it appears to be working, although it said "PT100" but was reading a correct value ... so I don't think "reset" actually reset the zero value. That seems like another bug. (This is reproducible -- it's nice to know reset isn't actually a reset!)
Power cycled, and it then seems to be working fine ... PT100 shows "overflow", and then setting the zero value to 1000 works ok.
So I think there's some sequence of events that I went through (I had been using a thermistor before) that got it into this confused state. I've tried going back over some similar steps but can't reproduce it.
Further -- the "zero" setting actually persists if you go from 4RTD to Thermistor and then back to 4RTD even though it says "PT100", so they are not properly resetting values. If you manually select "PT100" then it's ok.
Horrible.
