Edit: After browsing the other stickies, I see I may have posted this in the wrong section as this is not a meter issue that I know of. Probably should have been posted in the discussion section. Sorry about that.
Hi all, I just got this meter, not really needing it, but wanting to support eevblog and the fact its hack-able and encouraged.I havent used many settings on it yet, but I was trying to get the temperature of my hot end on my 3d printer. Seeing a large discrepancy, I wanted to find a way to see if the meter was off. I am almost positive the majority of the error is due to not a good thermal couple. Either way, I dont know how to really calibrate these and the only thing I could think of was boiling water.
I noticed it said my boiling point was exactly 97C. Im not up in the mountains, so shouldn't this be closer to 100C. Is there a way to offset it? Is boiling water not a true way to check an accurate temp?
Also when looking at a K type theralcouple chart, my ambient temp is 19C, shouldn't I be measuring .758mV? I measure -.085mV when trying to check what the thermalcoupler is outputting.
Thanks.
