Can’t get it to download new firmware for P20

[John_H]

For the past year, with the older firmware, I had been experiencing a problem with the output wattage not jiving with the amperage calculation.

P20 calibration question

Under very similar output loads of ~175W the current output amperages between my two P20s are significantly different. Can anyone explain why the discrepancy (over 20%) is so large? I thought the relationship between wattage and amperage was straight-forward math. Is there something else which needs to be calibrated for my two P20s? [image] [image]

Today’s firmware update fixed it - perhaps it was the newer “oscillator” version?
