Impedance Calibrator
Model M550 Impedance calibrator is designed for calibration of LCR meters. The calibrator consists
of several banks of resistance, capacitance and inductance standards of fix decimal values. Total range
cover values from 0.1 Ohm to 100 MOhm, 10 pF to 100 µF and 10 µH to 10 H. Calibrator offers four-pair
terminal and four terminal coaxial output connectors for calibration of precise and wide range LCR meters,
four-terminal and two-terminal non-coaxial output connectors for calibration of simple LCR meters and elder
LCR meters.
Basic applicable frequency range is from 20 Hz to 1 MHz in coaxial mode, and to 100 kHz in noncoaxial mode. Calibration memory contains both complex parameters of partial standards. The calibration
values can be displayed in wide range of frequently used pairs of complex impedance and admittance. Either
parallel or series equivalent model can be selected. The calibrator is equipped with reference positions OPEN
and SHORT terminals for easy elimination of test cables influence.
Part of the calibrator is built in level meter of voltage and frequency of test signal which is generated
by tested LCR meter during calibration.
M550 calibrator is equipped with large size colour LCD display. It can be controlled either manually
from front panel keypad or remotely using GPIB or RS232 interface. M550 is compatible with Meatest
automation software CALIBER.
