Hi there,
I have been making some research about how to measure the leakage currents in the 60601-1 with the measuring device (MD) described in 8.7.4.4 or Figure 12, unfortunately I did not find yet a reliable answer.
Usually I have been measuring them with a SecuTest SIII+
We went for pre-compliance testing to the test laboratory and the measurements done with the circuit described in figure 12 were all somehow different.
I build the device described in Figure 12 and now I am measuring with a multimeter Fluke 83 V which input impedance is 10 MOhm (> 1MOhm) and 100 pF (< 150 pF) which is in range.
I did not find until know the frequency response, where could I check that?
Or should I measure with an oscilloscope?
The oscilloscope that I have has a common ground that's why I am not confident to attach it to the MD in case it can produce a short cut
Or do you recommend an special multimeter/oscilloscope in order to measure it?
The second think is how should I read the value of the current. I am reading voltage (DC or AC depending on the part I will like to measure) then I am dividing this voltage through 1000 Ohm in order to get the current V/R=I is it that right?
I have read the norm thoroughly but I did not find any clear answers. It would be great if you could give me some advice
Thank you very much in advance. And thank you for the forum it has helped me a lot in the last years!
