The B&K Precision Corp. 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 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. The highly versatile 889B 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. The 889B has applications in electronic engineering labs, production facilities, service shops, and schools. It can be used to check ESR values of capacitors, sort and/or select components, measure unmarked and unknown components, and measure capacitance, inductance, or resistance of cables, switches, circuit board foils, etc. The key features are as following: 1. Voltage Measurements: • AC : True RMS, up to 600Vrms @ 40 ~ 1K Hz • DC : up to 600V • Input Impedance : 1M-Ohm 2. Current Measurements: • AC : True RMS, up to 2Arms @ 40 ~ 1K Hz • DC : up to 2A • Current Shunt : 0.1 Ohm @ > 20mA; 10 Ohm @ < 20mA 3. Diode/Audible Continuity Checks: • Open Circuit Voltage: 5Vdc • Short Circuit Current: 2.5mA • Beep On: < 25 Q • Beep Off: > 50 Q 4. LCR Measurements: • Test conditions Frequency : 100Hz/120Hz/1KHz/10KHz/100KHz/200KHz Level : 1Vrms / 0.25Vrms / 50mVrms / 1VDC (DCR only) • Measurement Parameters : Z, Ls, Lp, Cs, Cp, DCR, ESR, D, Q and 0 • Basic Accuracy : 0.1% • Dual Liquid Crystal Display • Auto Range or Range Hold • USB Interface Communication • Open/Short Calibration • Primary Parameters Display: Z : AC Impedance DCR : DC Resistance Ls : Serial Inductance Lp : Parallel Inductance Cs : Serial Capacitance Cp : Parallel Capacitance • Second Parameter Display: 0 : Phase Angle ESR : Equivalence Serial Resistance D : Dissipation Factor Q : Quality Factor • Combinations of Display: Serial Mode : Z -0, Cs - D, Cs - Q, Cs - ESR, Ls - D, Ls - Q, Ls - ESR Parallel Mode : Cp - D, Cp - Q, Lp - D, Lp - Q
