The Fluke 789 has a built-in 24V loop supply, which reduces the need for taking a separate power supply when testing transmitters.
The 789 is a Fluke Process Meter that combines a DMM and a Loop Calibrator in one rugged, handheld tool, for about the price you would expect to pay for a loop calibrator alone, making it an ideal maintenance tool. The Fluke 789 also features an IR port which allows logged data to be transferred to the optional FlukeView forms software for graphic analysis and reporting.

Digital Multimeter & Loop Calibrator in one tool
