Overview
The DTZ-WK Electronic Scanning Switch Automatic Test System is designed for switching and acquiring signals from RTDs and thermocouples, making it suitable for industrial applications requiring multi-point temperature measurements in bulk. The DTMC-mK301-WK scanning switch module, with its outstanding performance and unique features, provides an efficient and precise solution for rapid switching and data acquisition of multi-channel temperature signals. As a functional expansion to the mK301 high-precision thermometer readout, the DTMC-mK301-WK enables real-time viewing of multi-channel, multi-type temperature signals, synchronously displaying electrical measurement and temperature data for each channel.

System Applications
RTD Automatic Test System
When integrated with the mK301 high-precision thermometer readouts, standard references, and a temperature source, the DTMC-mK301-WK forms a complete 2/3/4-wire RTD measurement system. It supports flexible manual/automatic operation modes, displays resistance and corresponding temperature values in real time, and uses built-in algorithms for precise conversion. All data are presented directly on the mK301 interface, enabling efficient end-to-end processing from signal acquisition to result analysis.
Thermocouple Automatic Test System
When combined with the mK301 high-precision thermometer readouts, standard references, a temperature source, a cold-junction thermostat, and a Pt100 sensor, the DTMC-mK301-WK forms a complete thermocouple calibration system. It supports all common thermocouple types (S/R/B/K/N/J/E/T/WRe3/WRe5), automatically converts electrical measurements to temperature values in real time, and synchronously displays results on the mK301 interface. This delivers fully automated processing from signal acquisition to result output, meeting high-accuracy, multi-type thermocouple measurement requirements.
