881 In-Circuit ESR & DC Resistance Capacitor Tester

881 In-Circuit ESR (Equivalent Series Resistance) & DC Resistance Capacitor Tester is an essential tool for anyone working with printed circuit boards (PCBs). Designed specifically to measure ESR on capacitors within the range of 0.47uF to 2200uF, this tester allows users to troubleshoot capacitors both in-circuit and out of circuit. The ability to perform in-circuit testing saves significant time and effort, making the 881 an ideal choice for professionals who need to quickly identify faulty capacitors in electronic devices.

With a 100kHz output test frequency and a 15mVp-p output test voltage, the 881 ensures that solid-state devices are not inadvertently activated during testing. The device is microprocessor-controlled, ensuring accurate, reliable measurements, and it also features an automatic discharge function to safely discharge capacitors after testing. For added convenience, the 881 comes with a one-handed tweezer test probe, making it easy to operate in confined spaces or on densely populated PCBs.
