A 24V DC power supply is supplying around 2.4A to a pure resistive load. The input voltage is 230Vrms. So I estimated the rms current drawn from the power network as:
P/230 = (24*2.4)/230 = 250mA.
And with a multimeter this current is measured as around 260mA. So it was consistent.
But when I measured with a current clampmeter(which is very new with a calibration certificate), the clampmeter shows around 430mA.
(I measure the rms value of the Line current in both multimeter and clampmeter cases)
Here is the manual of the clampmeter. And under the electrical specifications it provides the following:
And here is the part from the calibration certificate:
Given the electrical characteristics and the calibration information, is 430mA measurement for a 260mA current expected for the provided error range or something is wrong?
