The precise LCR Meter series are automatic, user programmable instruments that provide high reliability and great precision for measuring a wide variety of impedance parameters. The frequency range of LCR-819.829 covers from 12Hz to 100kHz, LCR-817.827 from 12Hz to 10kHz, LCR-816.826 from 100Hz to 2kHz, and LCR-821 from 12Hz to 200kHz. The basic accuracy is 0.1% for LCR- 827/829/816/826, 0.05% for LCR-817.819/821. The measured results can be displayed on the high quality LCD monitor with decimal points and units. The measured result resolution is five full digits for Inductance (L), Capacitance (C), Resistance (R) and absolute value of impedance (|Z|) [four full digits for Dissipation factor (D), Quality factor (Q), R with C, R with L, 2 digits after decimal dot for phase angle (θ)]. In the meantime, the LCD monitor is also shown the control status and parameters of settings. The keypads are easy for menu programming. The LCR Meters’ test fixture (option) is a method of convenient, reliable, guarded 4-terminal/2 wires connection of radial and axial leaded components to the LCR Meters. Test conditions can be stored and recalled from internal memory that will reduce the setup time for measurement preparing.
