Both new bench LCR meters provide variable AC test signal levels from 5 mVrms to 2 Vrms, a built-in DC bias source, and three AC current ranges via the selectable 30/50/100-Ω AC source impedance setting. The 30-Ω internal impedance setting provides up to 66.7 mArms of drive current that is sufficient for testing large inductors and transformers. With a full array of test features and remote interfaces including a handler interface, the 894 and 895 models are suitable for characterizing a variety of components in production and laboratory environments.
DC biasing is a commonly used method to measure the capacitance of ceramic, MLCC, polyester, and other types of capacitors with high dielectric constants. Due to the change in capacitance when a DC voltage is applied, users must control the DC voltage to obtain a deterministic measurement result. B&K Precision’s 894 and 895 LCR meters provide this capability with a built-in DC bias source adjustable from -5 V to 5 V.
The 894 and 895 models also feature an intuitive interface with a bright 4.3-in. color LCD display that displays both primary and secondary measurements along with all test signal parameters on one screen. On the front panel, users can quickly access the built-in DC bias source function and easy-to-view zoom display mode with voltage and current monitoring. A USB host port enables external storage of measurement data logs, instrument setups, and screenshots.
Additionally, the new LCR meters provide auto level control, DC resistance measurement, a bin sorting function with pass/fail indicator, cable-length compensation, and a 201-point programmable list-sweep function. An optional test fixture (TL89T1) is available for various transformer measurements: primary/secondary inductance (L1, L2), turns ratio (N, 1/N), mutual inductance (M), and direct current resistance (R2).
On the rear, the instruments offer a 36-pin handler interface for easy integration with a component handler and standard SCPI-compliant USB (USBTMC or Virtual COM), RS-232, LAN interfaces for programming and remote control, and GPIB (model 895).
Each unit is shipped with the following standard accessories: Kelvin clips, shorting bar, and 4-terminal test fixture for convenient measurement of axial and radial lead type components.
Available immediately, B&K Precision’s new 894 and 895 bench LCR meters are backed with a three-year warranty and listed at a price of $3,625 and $5,525 respectively.
