ESR Meter

Hello all--newcomer here,

I just purchased a Peak ESR70 a couple weeks ago, in deference to the "blue" kit, and found this thread while searching for more info. It works quite nicely however I found the leads to be absurdly short and the supplied crocodile (alligator here in Florida) clips to be worthless for in-circuit testing.

The lead length was an easy fix, I cut the twin coax line off of a cheap set of "ear-buds" and used both the shield and center of each cable for each pole of the tester's input.

To address the in-circuit issue I made up a set of tweezers from Popsicle sticks--nothing magical in the construction, just cut the pieces/parts to fit and glue 'em up--I built up each leaf (tweeze?) with stacked pieces to provide a grip and then applied the heat-shrink tubing.

The probe tips are 1" brass escutcheon pins bent up as needed and epoxied in place--I have since bent the probe tips inward so as to grab solder pads more forcefully. In use I clip the croc's to the exposed head of the pins.

It all works well and will calibrate to 0.00Ω with no problems...
