Manual Overview
The B&K Precision Models 885 and 886 LCR/ESR Meters are advanced handheld instruments designed for measuring inductors, capacitors, and resistors with high accuracy. They offer both AC and DC impedance measurements, making them versatile tools for various applications in electronic engineering labs, production facilities, and service shops. The meters feature auto or manual ranging and allow selection of test frequencies from 100Hz to 100KHz, with test voltages of 50mVrms to 1Vrms. The dual display enables simultaneous measurements of primary parameters like AC impedance (Z), DC resistance (DCR), serial and parallel inductance (Ls, Lp), and capacitance (Cs, Cp), as well as secondary parameters such as phase angle (Q), equivalence serial resistance (ESR), dissipation factor (D), and quality factor (Q).
For troubleshooting, the manual provides a detailed flow for open and short calibration, essential for accurate measurements. Error codes and diagnostics are not explicitly detailed, but the manual emphasizes the importance of understanding impedance parameters and the use of series or parallel modes. Calibration and adjustments are facilitated through open/short compensation and range hold features. Board-level guidance is not specifically addressed, but the instrument’s capabilities allow for comprehensive component analysis and measurement.
Quick Issues Covered
- Diagnose open/short calibration issues for Models 885 & 886.
- Resolve power-up failures with battery replacement and recharging.

Basic Usage and Operation Tips
Before using the Bk-precision-886, ensure the device is properly calibrated and the batteries are fully charged. Select the appropriate measurement mode using the rotary switch. Always connect the test leads correctly: black lead to the common (COM) terminal and red lead to the appropriate input terminal based on the measurement type. For voltage and resistance measurements, connect the probes across the component or circuit points. When measuring current, connect the meter in series with the circuit. Use the hold function to freeze readings for easier analysis.
Troubleshooting and Maintenance
If the device displays erratic readings or no display at all, check the battery condition and replace if necessary. Inspect test leads for damage or wear and replace if faulty. Clean the device regularly with a soft, dry cloth and avoid exposure to moisture or extreme temperatures.
