Hi All,
So I've finally got around to testing my newly built Heatermeter. Sadly I'm experiencing an issue with the Thermocouple readings being way too high.
I've resoldered the amplifier a couple of times and still no luck - I guess I'll need to resolder / replace the caps next to ensure they're correct. Continuity looks okay in accordance with the thermocouple testing page.
In essence it looks like the readings are basically double what they should be, it's current sat at 137 degrees fahrenheit. If it helps, when the probe is first connected it starts counting down slowly from 700-800 before settling.
I've ordered another amplifier to check if the current one is at fault.
Thank you in advance for any help as I'm pulling my hair out trying to get this working!
