M550 Data Sheet
Impedance calibrator M550 is device designed for calibration of LCR meters in frequency range up to 1
MHz. It contains resistance standards in range 100 mΩ up to 100 MΩ of decimal nominal values, partial
capacitance standards in range 10 pF to 100 µF and partial simulated inductance standards in range from
1 µH to 10 H. RC T-type passive network is used for inductance simulation. Calibration values of
both complex parameters of partial standards are displayed in one of preselected pair of parameters. Precise,
temperature independent and long life stable components are applied on positions of partial standards.
The calibrator offers either coaxial output terminals for calibration of four-pair terminal LCR meters,
and banana four mm terminals for two- and four-wire connection. OPEN and SHORT reference positions are
available as well. Calibrator is equipped with meter of test signal which displays frequence, voltage
nad current of test signal. Easy recalibration system offers either full recalibration in all spot
frequency points or simplified offset calibration. History of calibration values of partial standards
at reference frequency 1 kHz can be easily recalled.
All functions of the calibrator can be controlled using IEEE488 bus or RS232 interface.
