M-500B

Impedance Calibrator

Impedance calibrator M-500B is instrument aimed for calibration of RLC meter in frequency range to 20 kHz. It contains 9 resistance standards in range of values 100 mΩ up to 10 MΩ in decade series, 7 partial capacity standards in range of values 10 pF to 10uF in decade series and 5 partial inductance standards in range of values 1 mH to 10 H in decade series. Basic connection of the impedance calibrator to the calibrated RCL meter is the coaxial four-pair terminal one, by BNC connectors mediation. Entry of new calibration data is done from keyboard of the device. Access to the calibration data and their change execution is protected by software. All functions of the calibrator can be controlled by means of IEEE488 bus or RS-232 interface.
