TECHNICAL DATA Fluke 787B and 789 ProcessMeter Double the troubleshooting power so you can do more, while carrying a lot less The Fluke 787B and 789 ProcessMeter double troubleshoot- ing capabilities by combining the power of a safety rated digital multimeter and mA loop calibrator into a single, compact test tool. Whether you only need to source and simulate mA, or need a 24V loop power supply, Fluke has a ProcessMeter test tool designed specifically to meet your needs. Based on the trusted measure- ment capabilities of the Fluke 87 DMM, the 787B and 789 add the ability to measure, source and simulate mA with the accuracy and resolution you would expect from a Fluke mA loop calibrator, giving you the ideal tool for troubleshooting and calibrating current loop applications. With Fluke Connect mobile app and desktop software compatibil- ity technicians can wirelessly monitor, log, and share data from the field with their team anytime, from anywhere*. 787B and 789 key features 20 mA dc current source/measure/simulate Simultaneous mA and % of scale readout DMM designed to meet 1000 volt IEC 61010 CAT III and 600 V CAT IV standards Fluke Connect compatibility for wireless data logging (with IR3000FC module)* Precision 1000 V, 440 mA true-rms digital multimeter Frequency measurement to 20 kHz Min/Max/Average/Hold/Relative modes Diode test and continuity beeper KEY DMM MEASUREMENTS Manual step (100 %, 25 %, Coarse, Fine) plus Auto Step and Measure ac and dc volts, ac and dc Auto Ramp current, resistance, continuity, and frequency Externally accessible battery for easy battery changes KEY mA LOOP FUNCTIONS 789 additional features 20mA current source/simulate, 24 V Loop power supply simultaneous mA and % scale readout, and 24 V loop power supply (789 only) HART mode setting with loop power (adds 250 ohm resistor) SAFETY RATED FOR INDUSTRIAL APPLICATIONS CAT IV 600 V/CAT III 1000 V *Requires Fluke IR3000FC module (not included) Not all models are available in all countries.
