ValueTronics 889B LCR表

"The 889B is a 200 kHz LCR Meter from BK Precision. An LCR meter is a piece of electronic test equipment that measures inductance (L), capacitance (C), and resistance (R) of electronic components. The LCR meter accurately measures these elements on an electronic device, usually one subjected to an alternating current (AC) voltage source. The LCR meter measures the current through and voltage across the device under test.","Additional Features:","The BK Precision 889B Synthesized In-Circuit LCR\/ESR Meter is a high accuracy test instrument used for measuring inductors, capacitors and resistors with a basic accuracy of 0.1%. Also, with the built-in functions of DC\/AC Voltage\/Current measurements and Diode\/Audible Continuity checks, the 889B can not only help engineers and students to understand the characteristics of electronics components but also being an essential tool on any service bench.","The BK Precision 889B is defaulted to auto ranging. However, it can be set to auto or manual ranging by pressing the Range Hold key. When LCR measurement mode is selected, one of the test frequencies, 100 Hz, 120 Hz, 1 kHz, 10 kHz, 100 kHz or 200 kHz, may be selected on all applicable ranges. One of the test voltages, 50mVrms, 0.25 Vrms, 1 Vrms or 1 VDC (DCR only), may also be selected on all applicable ranges. The dual display feature permits simultaneous measurements. When DC\/AC voltage\/current measurement mode or the Diode\/Audible Continuity Check mode is selected, only the secondary display will be used to show the result of the measurement.","This highly versatile meter can perform virtually all the functions of most bench type LCR bridges. With a basic accuracy of 0.1%, this economical LCR meter may be adequately substituted for a more expensive LCR bridge in many situations. Also, with the basic accuracy of 0.4% in voltage and current measurements, the 889B performs the functions of a general purpose Digital Multi-Meter and can be used to replace the DMM on a service bench."
