The RIO4000 is the RTD measure and simulate module for the Meriam MFT 4000 Series Multi-Function Tester. The module accurately measures or simulates the resistance of 22 different RTD sensor types with nominal resistance to 4000 ohms. 2-, 3-, and 4-wire RTD Measurement for various RTD types; platinum, copper, nickel or iron. Various alpha coefficients are supported. The module can simulate temperature to all conventional or smart temperature transmitters and signal conditioners.

The MFT converts measured resistance to a corresponding temperature value and displays the value in the userselected temperature engineering units (°F, °C, °R or °K). Ohms can also be displayed for direct reading or troubleshooting. Pt 100 RTDs probes are available from Meriam for use with the module. The Meriam RTD probes are 4-wire, DIN Class A probes, which come complete with handle, 5' coiled cable, and connector. Accessory connectors are available to connect to any RTD or temperature transmitter for measurement or simulation applications. The RTD Simulation mode can be setup by entering a specific temperature or a range of temperatures that can be set up for stepping and ramping functions.
