Description
The Fluke 789 ProcessMeter is the ultimate troubleshooting tool for electricians and instrumentation professionals. It combines the functionality of a full-featured loop calibrator with the power of a CAT III 1000 V, CAT IV 600 V safety rated digital multimeter, and the wireless capabilities of Fluke Connect connectivity with optional IR3000FC module. The 789 has a large, dual display with two levels of backlighting and externally accessible fuse and batteries for easy replacement. And its built-in, selectable 250-ohm HART® resistor eliminates the need to carry a separate resistor. The 789 also has a built-in 24-Volt loop supply, which reduces the need to carry a separate power supply when doing offline transmitter testing. You can also add the wireless data logging capabilities of the Fluke Connect™ mobile app to log data wirelessly to your smart phone and review it from a remote location. Includes
AC175 Alligator Clips Four (4) AA 1.5 V alkaline batteries (installed) TL71 safety-designed test lead set
Features
Compact digital multimeter and mA loop calibrator solution Full-featured mA loop calibrator with built-in 24v Loop Power Quickly and easily troubleshoot every part of a control loop Large, bright dual-measurement display
