Datasheet

Now compatible with Fluke Connect™ App

The Fluke 789 ProcessMeter is the ultimate troubleshooting tool for electricians and instrumentation professionals, combining the functionality of a loop calibrator with the power of a digital multimeter. By equipping the 789 with a temperature measurement module and the wireless data logging capabilities of Fluke Connect™ with ShareLive™ video call (sold separately), process technicians can now do a lot more while carrying a lot less. And with its built-in, selectable 250 ohm HART® resistor, it eliminates the need to carry a separate resistor with you.

Includes:

• AC175 Alligator Clips
• Four (4) AA 1.5 V alkaline batteries (installed)
• TL71 safety-designed test lead set

Features

• 24 V Loop power supply
• Very large dual display
• Enhanced backlight with 2 brightness settings
• 1200 ohm drive capability on mA source
• HART mode setting with loop power and a built-in 250 ohm resistor
• 0% and 100% buttons to toggle between 4 and 20 mA sourcing for a quick span check
• Externally accessible fuses for easy replacement
• Infrared-port to process data in FlukeView Forms (V2.1) software
