Multimeter and current loop calibrator in one instrument.
The ultimate Fluke 789 multimeter for loop calibration, the Fluke 789 uses 24 volt loop power, reducing the need to power transmitters externally when calibrating in the field. And thanks to its built-in switchable 250-ohm Hart® resistor, you no longer have to carry a separate resistor for calibrating Hart instruments. For the process technician this means: do more with a modern tool and at the same time carry less with you.
