Overview The Fluke 787B ProcessMeter™ doubles troubleshooting capabilities by combining the power of a safety rated digital multimeter and mA loop calibrator into a single, compact test tool. Based on the trusted measurement capabilities of the Fluke 87 DMM, the 787B adds 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 compatibility technicians can wirelessly monitor, log, and share data from the field with their team anytime, from anywhere*. 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 Manual step (100%, 25%, Coarse, Fine) plus Auto Step and Auto Ramp Externally accessible battery for easy battery changes Specifications Measurement function Range and resolution Best accuracy (% of reading + LSD) V dc 400.0 mV, 4.000 V, 40.00 V, 400.0 V, 1000 V 0.1% + 1 V ac (true-rms) 400.0 mV, 4.000 V, 40.00 V, 400.0 V, 1000 V 0.7% + 2 mA dc 30.000 mA .05% + 2 A dc 1.000 A (0.440 A continuous) 0.2% + 2 A ac 1.000 A (0.440 A continuous) 1% + 2 Resistance 400.0 Ohms, 4.000 k, 40.00 k, 400.0 k, 4.0 M, 40 M 0.2% + 1 Frequency (0.5 Hz to 20 kHz) 199.99 Hz, 1999.9 Hz, 19.999 kHz .005% + 1 Diode test 2.000 V (shows diode voltage drop) 2% + 1 Continuity Beeps for resistance < approx. 100 ohms Output function Range and resolution Drive capability Accuracy (% of span) DC current output (Internal battery operation) 0.000 to 20.000 mA or 4.000 to 20.000 mA, (selectable at power-up) Over-range to 24.000 mA 24 V compliance or, 1,200 ohms, @ 20 mA 0.05% DC current simulate (Ext. 15 V to 48 V loop supply) 0.000 to 20.000 mA or 4.000 to 20.000 mA, (selectable at power-up) Over-range to 24.000 mA 1000 ohms, @ 20 mA 0.05% Current adjustment modes Manual: Coarse, Fine, 25% and 100% step Automatic: Slow Ramp, Fast Ramp, 25% step Temperature range of 18 °C to 28 °C, for one year after calibration General specifications Maximum voltage applied between any jack and earth ground 1000 V RMS Storage temperature -40 °C to 60 °C Operating temperature -20 °C to 55 °C Temperature coefficient 0.05 x (specified accuracy) per °C (for temperatures < 18 °C or > 28 °C) Relative humidity 95% up to 30 °C; 75% up to 40 °C; 45% up to 50 °C; 35% up to 55 °C Vibration Random, 2 g, 5-500 Hz Shock 1 meter drop test Safety IEC61010-1, Pollution Degree 2/IEC61010-2-033, CAT IV 600 V/CAT III 1000 V Size (HxWxL) 50 x 100 x 203 mm (1.97 x 3.94 x 8.00 in) Weight 600 g (1.3 lbs) Battery Four AA alkaline batteries Battery life 140 hours typical (measurement), 10 hours typical (sourcing 12 mA) Warranty Three years
