A 9-V battery or an optional ac wall adapter can power the Model 881 portable in-circuit equivalent-series resistance (ESR) and dc resistance (DCR) capacitor tester. It measures ESR and DSR from 0.1 ...

10 kHz. Additional measured parameters include Z, L, C, DCR, D, Q, and B;. The meter features a large, easy-to-read LCD display, autoselection, and a 0.5% basic accuracy.

A portable in-circuit ESR and DCR capacitor tester, the Model 881 uses a standard 9-VDC battery or optional AC wall adapter as its power source. The unit measures the equivalent series resistance of ...

Got a bunch of questionable electrolytic caps sitting in your junk bin? Looking to recap a vintage radio chassis? Then you might need to measure the equivalent series resistance of the capacitors, in ...
