The MFT 4010 is a combination calibrator/HART communicator that reduces the time spent on field calibrations. The MFT 4010 delivers the versatility of a modular calibrator and the convenience of HART communications in one hand-held unit. Users can view up to four measurements simultaneously on the high resolution LCD or compare HART primary variable and analog output values to corresponding measurements by the NIST traceable MFT modules. A voltage and current meter is integral to the base unit. All HART field devices can be config-ured, polled, and trimmed using HART communications. Documenting is standard for calibration procedure prompting in the field and full documentation of as found and as left results. The instrument supports pressure and temperature transmitters, switches and indicators plus P/I and I/P converters and Hart communication, CE, Hart leads, batteries, serial cable and boot.
