As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

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.

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 ...

Optimized for high-speed testing and low ESR measurements on tantalum and other types of capacitors, the 1930 capacitance meter features a fast settle time and quick recovery from open or shorted ...
