Temperature probe calibration

Is it possible to calibrate the temp. probe? My both probes indicate 85.1, I don't think this is real temperature in the tank. Any thoughts on that?

They are factory calibrated.
It's very odd that both are showing wrong temperatures.
You can do this if you want to offset the probes:
Code: Select all
ReefAngel.Params.Temp[T1_PROBE]-=50;
Place this right after ReefAngel.ShowInterface();
This will offset -5 degrees to T1 probe.

Actually, it won't work.
It will still display without the offset.

I put the probes side by side into the tank and these are the readings.

OK, it gets better. I removed these probes and put them on my desk. They indicate 78 and 79 F (the room temp is 81), I think I can live with that error. I guess I may have some electric current leak in the tank. Would this interfere with the probe reading? I will check it tomorrow turning off all the appliances one by one. Does it make sense?

Weird.
Do you have another thermometer to test the water temperature?

Yes, the old thermometer shows 80.1
