Fluke 289 True-RMS Logging Multimeter with TrendCapture | Portable Field Diagnostics

Overview

The Fluke 289 True-RMS Logging Multimeter with TrendCapture is a compact, rugged handheld tool built for high-precision measurements in challenging environments. Instead of waiting to review data later on a PC, you can quickly document design performance in the field and visually confirm what happened, all in one device.

With its built-in data logging and a real-time clock, you can save measurements, name them, and recall them when needed. Its standalone operation makes it a reliable companion for commissioning, maintenance, and troubleshooting tasks where clear, documented measurements matter.

Key capabilities

• True-RMS AC voltage and current handling complex, non-linear signals with improved accuracy across the spectrum.
• TrendCapture graphically displays logged data sessions, helping you identify anomalies as they occur. Zoom up to 14x for deeper inspection.
• Selectable AC filter (smoothing mode) reduces rapid fluctuations and noise for steadier readings on noisy signals.
• Low impedance voltage function helps eliminate ghost voltages when checking for live or absent power.
• Large 50,000-count, 1/4 VGA display with white backlight presents multiple data sets at once for quick assessment.
• Auto time stamping records when measurements were saved, supporting traceability in field reports.
• Long battery life — about 100 hours in standard operation, up to 200 hours in logging mode — with six AA cells.

In practice, technicians use the 289 to monitor motor drive signals, verify power quality, and keep a running log of measurements over a project or shift. The device’s design emphasizes one-handed use, a clear display, and robust performance in busy environments.

What you get and how it helps

• Complete kit: manual, six AA batteries, TL71 silicone test leads, probe holder, and two AC72 alligator clips, so you can start testing right away.
• Optional accessories include the 80BK-A temperature probe for temperature-related checks in electrical equipment.
• Safety and reliability: CSA, UL, TUV, and CE approvals with CAT III 1000 V and CAT IV 600 V safety ratings.

The Fluke 289 is designed for field engineers and technicians who need dependable data, intuitive visualization, and flexible logging. It pairs precise measurements with a portable form factor, letting you capture and review performance on the fly without compromising accuracy or clarity.
