1. Introduction 1.1 General The B&K Precision Models 885 & 886 Synthesized In-Circuit LCR/ESR Meter is a high accuracy hand held portable test instrument used for measuring inductors, capacitors and resistors with a basic accuracy of 0.5%. It is the most advanced handheld AC/DC impedance measurement instrument to date. The 885 or 886 can help engineers and students to understand the characteristic of electronics components as well as being an essential tool on any service bench. The instrument is auto or manual ranging. Test frequencies of 100Hz, 120Hz, 1KHz 10KHz or 100KHz (886) may be selected on all applicable ranges. The test voltages of 50mVrms, 0.25Vrms, 1Vrms or 1VDC (DCR only) may also be selected on all applicable ranges. The dual display feature permits simultaneous measurements. Components can be measured in the series or parallel mode as desired; the more standard method is automatically selected first but can be overridden. The Model 885 and 886 offers three useful modes for sorting components. The highly versatile Models can perform virtually all the functions of most bench type LCR bridges. With a basic accuracy of 0.2%, this economical LCR meter may be adequately substituted for a 1

more expensive LCR bridge in many situations. The meter is powered from two AA Batteries and is supplied with an AC to DC charging adapter and two AA Ni-Mh Rechargeable Batteries. The instrument has applications in electronic engineering labs, production facilities, service shops, and schools. It can be used to check ESR values of capacitors, sort values, select precision values, measure unmarked and unknown inductors, capacitors or resistors, and to measure capacitance, inductance, or resistance of cables, switches, circuit board foils, etc. The key features are as following: z Test condition: 1 Frequency : 100Hz / 120Hz / 1KHz / 10KHz / 100KHz (886) 2.
