Meatest manufactures high-precision layout electrical calibration standards, programmable decade boxes, and measurement instruments for industrial automation and testing.
Meatest is a specialized manufacturer of electrical calibration equipment and measurement standards, serving calibration laboratories and industrial testing facilities. The company designs and produces a range of sophisticated instruments, including multifunction calibrators, resistance decade boxes, and impedance standards. Their products are engineered to support automated simulation of various physical quantities such as temperature, pressure, and force through precise resistance generation.
A key highlight of Meatest's offerings is the M600 series of programmable resistance decade boxes (M631, M632, M641, M642), designed to eliminate zero-resistance effects and provide stable, accurate simulations for RTDs and other sensors. These instruments feature advanced connectivity options like RS232, USB, LAN, and GPIB to integrate seamlessly into automated calibration systems (ATS). Meatest also provides dedicated software solutions, such as WinQbase and Caliber, to facilitate automated calibration procedures, uncertainty calculations, and certificate generation in compliance with ISO 17025 standards.

The M600 series (M631, M632, M641, M642) are programmable resistance decade boxes used for the automated simulation of resistance sensors, such as temperature (RTD), pressure, position, and force sensors.
Meatest decade boxes can be controlled remotely via RS232, USB, LAN, or GPIB (IEEE488) interfaces using SCPI commands to integrate with automated calibration systems.
The manufacturer recommends the WinQbase + Caliber software package for automated calibration, uncertainty calculation, and certificate printing in accordance with ISO 17025.
The central ground terminal (protective earth) connects to the metal case. It is recommended to connect it to the 'grey' output terminals if the connected meter is not grounded.
The SHORT key replaces the main resistance value with a short circuit simulation. The short circuit must then be connected to the output terminals by pressing the OPER key.
