The BK Precision 890C Dual-Display Handheld Capacitance Meter, 11,000-Count, 50 mF is a handheld capacitance meter that measures capacitance up to 50 mF. The 890C 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 890C Capacitance Meter measures capacitance by applying a constant current that briefly charges and discharges the connected capacitor. The 890C includes functions such as a 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.
