Noise?


 
I see a little red or sometimes yellow squiggly line above my Probe 1 temp and when I hover my mouse over it it says Noise:7

I can't find any info on this on the heater meter display wiki. I'm assuming it has to do with the TC or probe but I'm not sure which, and how to go about correcting it/ if it needs corrected?
 
Hmm.... noise...
clean your board with isopropyl alcohol, particularly around the probe jacks and resistors and caps that are between the jacks and the ATMega. Perhaps enable the "A/C input line filter" in the HM config, or try a different power supply...
