AC voltage and calibration

[nickdd]

Hi,

Yes, but I am using SCT013-10 and SCT-013-20 (10A and 20A) 1V versions.
But why do I see voltages higher than 1 volt in the raw output?

100W bulb: [sensor:094]: 'ai1': Sending state 1.01000 V with 3 decimals of accuracy
1500W heater:[sensor:094]: 'ai1': Sending state 1.24500 V with 3 decimals of accuracy

=> so even for low wattage I have raw values of > 1V
But according to specs of SCT013 I believe it should be within 0V and 1V range?

So I understand the calibrate_linear but not why I have raw values that seem too high?
