Fluke Multimeter, 19.99kHz Maximum Frequency, 140h Battery Life - FLUKE-787B

This handheld true RMS multimeter combines a precision digital multimeter with an mA loop calibrator to measure, source and simulate DC loop currents within industrial control systems. It is intended for field technicians working on process instrumentation and control loops where simultaneous current and percentage-of-scale readouts aid diagnostic and calibration tasks.

Features & Benefits

• ±0.05% DC current accuracy provides high-accuracy DC current meter performance
• AC measurement to 19.99kHz enables AC current 19.99 kHz multimeter capability
• 0.1% DC voltage accuracy supports precise voltage diagnostics
• 140h battery life offers a multimeter with 140h battery life for extended field use
• Internal sourcing of 0–20.000mA drives loops up to 24mA with 24V compliance
• True RMS measurement ensures correct readings on non‑sinusoidal signals

Applications

• Suitable for troubleshooting 4–20mA industrial control loops
• Ideal for calibrating transmitters and loop-powered instruments
• Used for verifying controller input scaling via simultaneous per cent readouts
• Can be used for frequency checks on signal carriers up to 20kHz
• Used with field devices where limited external loop supply is present

How does it handle sourcing and simulation in a live loop?

It can source 0.000–20.000mA from its batteries with 24V compliance and simulate currents when an external 15–48V loop supply is present, allowing both internal-drive and external-supply simulation.

What indications and modes assist in signal verification?

The instrument offers dual readouts of mA and per cent of scale Plus Min/Max/Average/Hold/Relative modes to capture transient behaviour and steady-state values.

How long will batteries last during sourcing compared with measurement?

Typical measurement operation yields about 140h from four AA alkaline batteries, while continuous sourcing at 12mA typically runs for around 10h.

What safety and environmental tolerances support industrial use?

It is rated for high-voltage exposure up to 1000V between any jack and earth, operates from -20°C to 55°C, and withstands random vibration and a 1m drop test.
