Title: Current Probe Post by: Sat on November 23, 2023, 04:03:17 04:03 Hi All,
I am planning to buy Micsig CP503B current probe (0 to 30A 50Mhz bandwidth) for switching power supplies testing. It is relatively low in price compare with other manufacturers. https://www.micsig.com/CP1003/ Does any one using this current probe? How the accuracy and reliability? please share your experience and comments. Thanks, Sat Title: Re: Current Probe Post by: mbyka on November 24, 2023, 09:06:30 09:06 did you see owon's current probes

We compared them to some other current probes we have, and we also tested them by putting them in-line with a current sense resistor. In the end we decided not to use them. The problem was they had a real delay in their response, and that delay was very variable. So we could never get them to line up with other measurements in the circuit, because even if we allowed for the delay, it seemed to change based on apparently random factors. It made them very difficult to use. |
