Temperature calibrationPosted: June 22, 2011
So I tried a little harder to calibrate the PT100 readings, although I don’t really have the right equipment for that.
Setting the target to 35 degrees.
Wait for the temperature to rise, and watch the PID output change.
Open the lid and quickly check the temperatures with all the thermometers I can find!
Repeat after filling the fridge with ice (sorry no pictures), and then apply linear calibration.
