Data Sheet 500 kHz / 1 MHz Precision LCR Meter Models 894 & 895 Features & Benefits n AC test signal voltage adjustable up to 2 Vrms n 3 AC current ranges, selectable via 30 , 50 or 100 internal AC impedance. The 30 setting provides up to 66.7 mArms of Industry-Leading Performance DC Biasing drive current, sufficient for larger inductors The 894 and 895 are high accuracy LCR meters Both the 894 and 895 feature a DC bias source and transformers. capable of measuring inductance, capacitance, which allows the meter to apply a DC signal n Built-in DC bias source adjustable from and resistance of components and materials at to the device under test to simulate in-circuit -5V to +5V / -50 mA to +50 mA DC or from 20 Hz to 500 kHz or 1 MHz conditions. n Fast measurement speed up to 13 ms/reading respectively. These LCR meters provide flexible AC and DC test signal configuration. AC test DC biasing is commonly used to measure to increase manufacturing throughput signal voltage is variable from 5 mVrms to capacitance of ceramic, MLCC, polyester and n Adjustable measurement speed for fast readout 2 Vrms, the AC current is adjustable up to other capacitors with high dielectric constants. or better accuracy 66.7 mArms, depending on the AC impedance These type of capacitors exhibit a significant n 201-point programmable list sweep function selected, and a DC bias signal can be added. The change in capacitance with a DC voltage applied. providing ability to sweep frequency, AC vivid 4.3-inch TFT LCD offers a clear view of all By controlling the DC voltage, users can obtain and DC bias voltage/current levels measured and setting values along with BIN a more deterministic measurement result. Other sorting comparator results and a handy Zoom applications include evaluation of n Auto-level control to maintain the feature that enlarges the measured values to full cored-inductors and junction capacitance of measurement signal applied to the DUT at a screen. With a basic accuracy of 0.05%, auto semiconductor devices. constant level level control (ALC), open / short / load correction n Test signal voltage and current monitoring and cable length compensation, these meter are The DC bias source is adjustable from -5V to +5V n BIN comparator function to sort components perfect tools for R&D, manufacturing and quality / -50 mA to +50 mA. Additionally the voltage in up to 10 bin locations control applications. or current levels can be swept while logging the resulting capacitance. n Handler interface for easy integration with a component handler n 1 meter cable compensation n 4-terminal fixture and Kelvin clip test leads included n Transformer test function with optional transformer test fixture TL89T1 Model 894 895 n Versatile trigger functionality (internal, Measurement parameters L, C, R, G, X, Z, Y, B, , Q, D, DCR external, bus and manual) Basic accuracy 0.05% n Standard USB, LAN, and GPIB (895 only) DCR measurement range 0.01 - 100 M interface for remote control using SCPI Test frequency range 20 Hz - 500 kHz 20 Hz - 1 MHz commands Technical data subject to change www.bkprecision.com B&K Precision Corp. 2020500 kHz / 1 MHz Precision LCR Meter Models 894 & 895 Front panel USB host port 4.3 TFT high Connect your USB flash drive resolution color Intuitive user interface Pass/Fail LED to conveniently save and recall measurement data logs, settings, and Easily change test parameters using the display indicators menu-driven front panel keypad. screenshots.
