Meatest M550 impedance calibrator
- Resistance standards from 0.1 Ω to 100 MΩ
- Capacitance standards from 10 pF to 100 μF
- Simulated inductance standards from 10 μH to 10 H
- Four pair coaxial terminal connection, four terminal connection, two terminal connection
- Calibration data from 20 Hz to 1 MHz
The Meatest M550 is an advanced impedance calibrator designed for the accurate calibration of LCR meters and impedance analysers. With a frequency range of 20 Hz to 1 MHz, support for four-terminal pair (4TP), four-wire (4W) and two-wire (2W) measurement configurations, and features such as open, short and load compensation, the M550 offers a complete and reliable solution for laboratories and calibration environments.
Precision and stability for LCR meter calibration
The M550 contains stable and temperature-independent resistance, capacitance and inductance standards, which are simulated with a passive RC T-network. The presence of open and short reference positions eliminates unwanted influences from test cables, resulting in extremely accurate measurements.
The built-in signal meter displays real-time measurements on a large LCD screen, including voltage, current and frequency. This makes the M550 suitable not only for manual calibration, but also for full automation via RS-232 and GPIB interfaces, supported by the Meatest CALIBER/WinQbase software.
Wide measurement range and high accuracy
The M550 supports a wide range of impedance parameters and measurement modes:
> Resistivity: 0.1 Ω – 100 MΩ (4TP & 4W), 1 Ω – 10 MΩ (2W)
> Capacitance: 10 pF – 100 µF (4TP), 100 pF – 100 µF (other modes)
> Inductance: 10 µH – 10 H (4TP), simulated via T-network
> Frequency range: 20 Hz – 1 MHz
Thanks to accurate temperature compensation (2-50 ppm/K depending on range) and annual stability of 0.01%, the M550 remains reliable for long-term use.
Comprehensive testing and analysis capabilities
With the ability to display parameters in complex pairs (Z/θ, Y/θ, Rs/Ls, Rp/Cp, etc.), the M550 provides in-depth analysis for:
> Component test and quality control of impedance devices
> Calibration of LCR meters, impedance analysers and network components
> Materials testing and dielectric analysis
> Electronic circuit research and development
User-friendly operation and connectivity
The M550 is designed for easy integration and ease of use:
> Large LCD display for instant display of measured values and settings
> Automated calibration via RS-232 and IEEE488 (GPIB)
> Support for open, short and load compensation for elimination of measurement errors
> Short warm-up time of only 15 minutes for fast and efficient measurements
