The Fluke 789 ProcessMeter combines these functions in one instrument, allowing technicians to troubleshoot electrical circuits and power or calibrate process loops without returning for additional equipment.\u003cbr\u003eLike the 787B, it provides True-RMS measurements to 1000 V and sources, measures and simulates 0–20 mA or 4–20 mA signals. The key upgrade is an integrated 24 V loop power supply, allowing a transmitter to be energized directly during calibration. A selectable HART mode adds a 250 Ω resistor while loop power is active, simplifying work with HART-connected instruments. Manual stepping, Auto Step and Auto Ramp support efficient control-loop checks.\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eProcessMeter with Loop Power Selection Guide\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eChoose the 789 when field work requires 24 V transmitter loop power or HART-mode loop resistance in addition to multimeter and mA calibration functions.\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eMarket Relevance\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eThe Fluke 789 is particularly useful in Pakistan's process plants, water treatment, fertilizers, pharmaceuticals, chemicals, oil and gas and food manufacturing.
