I built a PID years ago from the plans on susanminor.org. I had to replace the probe and now it seems to be off 50 degrees. I am comparing it to the maverick temp reading.
Is there a way to calibrate these?
Thanks..

Was it one of the internal Auber PIDs from the how-to guide on susanminor.org? If so, you can d/l the instruction manual from the Auber website. It will tell you how to do an autotune on the PID.
If it began reading 50 degrees off since you replaced the probe. Make sure you have the probe wired correctly. You can do this with a lighter, hold the lighter below the probe and watch the Auber. If the reading starts to drop instead of going up switch the wires. Next make sure you have the correct probe. There are many kinds of thermocouples and each kind will read different if the instrument is not set up for it. I think Auber mainly uses type K thermocouples. I really do not think the instrument needs calibrated just because you changed thermocouples.
Checked with a lighter. It raises temp when applied. I didn't think I would need to calibrate either. Going to read the manual I guess. Attached is the pic of the front of the unit (http://uploads.tapatalk-cdn.com/20161215/1f7df94ae84baea262b964eec764f4a8.jpg)

And it is a K style sensor
