THE MEAtest M500B impedance calibrator is designed as calibration standard for R, L, and C measuring devices at frequencies to 20 kHz. It is available from Power Parameters .
Measurement is made via the four-terminal Kelvin-style device clip. It can be controlled by keyboard or by RS 232 and IEEE 488 ports. This allows the instrument to be easily integrated into a calibration facility.
Resistance standards range from 100mΩ to 10MΩ. Capacitance is from 10pF to 10μ and inductance is from 1 mH to 10H. The instrument displays parameters in parallel or serial equivalent circuit format indicating quality factor for inductors and loss factor for capacitors.
