New P20 ..... more details please?

[John_H]

Finally, last but not least, a third question regarding discrepancies in the P20s display data screen which has really bugged me, since the problem appears to a faulty “calculator” algorithm:

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]
