High-precision multimeter and process calibrator for measuring and simulating electrical quantities, featuring an integrated mA loop function and HART communication The METRACAL CM Series redefines the standard for mobile calibration technology. As multifunctional process calibrators for electrical quantities, they combine the highest measurement accuracy with practical operation and state-of-the-art communication. With dual mode, programmable sequences, an integrated data logger, and Bluetooth® connectivity, these devices are ready for documented and efficient calibration processes in the lab, production, and field service. The METRACAL CM TECH expands on the PRO version with an integrated HART interface for direct communication with smart field devices. This allows transmitters and transducers to be not only electrically tested, but also configured and diagnosed-without additional hardware. The device combines precision, communication, and efficiency-making it the ideal tool for modern process instrumentation. Tests and configures HART-compatible field devices directly and without additional modules Accelerates commissioning and maintenance work through combined functionality Offers maximum signal stability and measurement accuracy Reduces downtime through rapid fault diagnosis in the process Future-proof integration into digitized calibration workflows. Process calibrator with integrated HART communication for parameterization, diagnostics, and calibration of smart field devices. Simulation and measurement of mA, mV, V, ohm, Hz, CPM, and temperature signals (TC/RTD) for service, maintenance, and commissioning. Integrated mA loop function with 24 V loop power supply for powering and testing 2-wire transmitters. Four freely configurable quick-access keys for frequently used measurement and/or calibration functions. Dual-mode for simultaneous signal output and measurement, plus a clear color display for efficient calibration processes. Expandable via software upgrade in the field-future-proof through optional activation of additional functions. “Made in Germany" quality- includes a DAkkS calibration certificate. Ideal for commissioning, service, and maintenance in automated process plants; communication, testing, and parameterization of HART transmitters; calibration of signal paths in process and automation systems; maintenance and service in chemical, pharmaceutical, and power plant operations; and diagnostics and functional testing of digital field devices.
