The BK Precision 894 is a high accuracy LCR meter capable of measuring inductance, capacitance, and resistance of components and materials at DC or from 20 Hz to 500 kHz. The LCR meter provides flexible AC and DC test signal configuration. AC test signal voltage is variable from 5 mVrms to 2 Vrms, the AC current is adjustable up to 66.7 mArms, depending on the AC impedance selected, and a DC bias signal can be added.
The vivid 4.3-inch TFT LCD offers a clear view of all measured and setting values along with BIN sorting comparator results and a handy Zoom feature that enlarges the measured values to full screen. With a basic accuracy of 0.05%, auto level control (ALC), open/short/load correction and cable length compensation, this meter is a perfect tool for R&D, manufacturing and quality control applications.
The 894 features a DC bias source which allows the meter to apply a DC signal to the device under test to simulate in-circuit conditions. DC biasing is commonly used to measure capacitance of ceramic, MLCC, polyester and other capacitors with high dielectric constants.
These type of capacitors exhibit a significant change in capacitance with a DC voltage applied. By controlling the DC voltage, users can obtain a more deterministic measurement result. Other applications include evaluation of cored-inductors and junction capacitance of semiconductor devices.
The DC bias source is adjustable from -5V to +5V / -50 mA to +50 mA. Additionally the voltage or current levels can be swept while logging the resulting capacitance.
