M550 Impedance Calibrator

Product catalog summary

Overview
The M550 Impedance Calibrator is designed for the calibration of LCR meters, offering automated calibration capabilities with a frequency range from 20 Hz to 1 MHz. It supports four-terminal pair (4TP), four-wire (4W), and two-wire (2W) configurations, and includes open, short, and load compensation to mitigate test cable influences.

Specifications

Resistance: Ranges from 0.1 Ω to 100 MΩ in 4TP and 4W modes, and 1 Ω to 10 MΩ in 2W mode. Calibration uncertainty varies by resistance value and configuration.
Capacitance: Ranges from 10 pF to 100 µF in 4TP mode, with a tolerance of 5% at 1 kHz.
Inductance: Ranges from 10 µH to 10 H in 4TP mode, with a tolerance of 15% at 1 kHz.

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.
