The BK Precision's Model 890C-220V Dual-Display Handheld Capacitance Meter, 11,000-Count, 50 mF, 220VAC is an 11,000-count handheld capacitance meter that measures capacitance up to 50 mF. Straightforward to operate, the BK Precision 890C-220V Capacitance Meter can make measurements quickly and simplifies the capacitance sorting process. Unlike other handheld instruments such as LCR meters that make measurements using an AC signal with a specific test frequency, the The BK Precision 890C-220V Capacitance Meter measures capacitance by applying a constant current that briefly charges, then discharges the connected capacitor. The 890C-220V includes many handy functions. The compare mode which supports 25 sets of High/Low limits, provides a convenient means to sort capacitors without needing to set up the meter each time. Data logging, Hold/Min/Max Average recording, tolerance, and relative mode features offer additional component troubleshooting tools.
