Impedance calibrator M550

for electrical measuring instrumentsdigitallaboratory

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. The 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 of course, supported in CALIBER/WinQbase calibration software.
