U2.00 Firmware has a minuscule bug to report. I have been working with thermocouples, as of late. Working with a Temperature calibrator, I needed to change the setting to Deg C to match the calibrator.
I pushed and held the SETUP button, until the top temp indicator began to flash. Then pushed the Up/Down arrow, which toggled the temperature scale from Deg F to Deg C. I continued taking readings and recording the results. After 2 minutes the temperature scale reverted back to Deg F except the main indication still read Deg. C. However the indication was clearly back to Deg F scale. (See attachment)
I obviously did not confirm the scale change, thus causing the display scale mismatch.
