Thanks Adam! I’m very excited to see what you’ve come up with on thermocouple measurements. It’s high on the priority list, but stability and logging are top right now.

David and Tom: The temperature sensor is internal to the ADC, which is this model:

The meter is calibrated to compensate for intrinsic offset in the ADC and gain errors in the ADS1292 PGA, but it’s not calibrated for any reference temperature. I hope this helps.
