I bought this ESR meter from eBay but I realized that the probes were too short for me to use comfortably and therefore I decided to do something about the probe length without compromising the overall accuracy of the meter.
To minimize interference from the EMI signal I decided to use RF shielded cable like the ones used for carrying audio signals(eg speaker wires)
I used 60cm long shielded RF cable, a pair banana plug and a pair of crocodile clip. You can easily swap the probes to use them on the capacitance meter also.
Original probe…too short for in circuit testing
Modified probe with crocodile clip-Very good for in circuit testing and out of circuit testing:
Modified probe with ordinary sharp pointed probes-Very good for in circuit testing (both under the circuit and components side where capacitors are many and crowded
