Impedance Calibrator Automated LCR bridge calibration Calibration data from 20 Hz to 1 MHz Four-terminal pair, 4W and 2W configurations Open, Short and Load compensation Model M550 Impedance calibrator is designed for calibration of LCR meters. The calibrator contains stable and temperature independent resistance standards, partial capacitance standards and partial inductance standards simulated by RC T-type passive network. Open and Short reference positions are available to eliminate influence of test cables. Calibration values of both complex parameters of partial standards are displayed on large LCD screen in preselected pairs of parameters as well as voltage, current and frequency readouts from built-in test signal meter. Philosophy of M550 is based on remote control and automated calibration. For this reason, the calibrator is equipped with RS-232 and GPIB interfaces and supported in CALIBER/WinQbase automated calibration software.
