Do you have a schematic about esr meter technicians recommend me to check the electrolytic first every time i come up with a dead circuit but i dont know how to measure it technicians recommend me to check the electrolytic first every time i come up with a dead circuit but i dont know how to measure it. Simple esr meter circuit this esr meter device provides the measurement of equivalent series resistance esr of capacitors the circuit diagram is very simple see fig 1 there is only two bipolar transistors of n p n conductivity type are used the circuit was described in july 2008 issue of radio magazine by y kurakin the device provides measurements of the equivalent series resistance in the range of 01 to 23 . Because an esr meter is essentially a low range ohmmeter long test leads from the cut can contribute errors to the esr reading esr can depend on external factors such as temperature or applied voltage so a capacitor may behave a bit differently in a real circuit than when it is being tested all by itself.
