Fluke 289 True-RMS Industrial Logging Multimeter 50000 count

Industrial Logging Multimeter for Electrical

The Fluke 289 is a true-RMS handheld multimeter designed for industrial troubleshooting and preventive maintenance. Its 50,000 count display provides high-resolution readings for voltage, current, and resistance. The integrated TrendCapture function logs data sessions and displays graphical trends on-screen without a PC. This tool targets electricians and technicians who need to capture intermittent faults and monitor equipment performance over time.

Verify Measurement Category

Before ordering, confirm that the measurement category rating matches the electrical environment where you will work. Ensure you have the appropriate test leads, probes, and temperature accessories for the specific parameters you intend to measure. The logging function requires sufficient internal memory for the intended session length, so review the expected data volume against the meter's storage capacity. Check that the display visibility suits your typical ambient lighting conditions.

Sustained Logging and TrendCapture Behaviour

During extended logging sessions, the meter continuously records measurements to internal memory for later review. TrendCapture renders this data as an on-screen graph, allowing immediate visual analysis of signal stability or drift without external software. The true-RMS architecture maintains accurate AC readings on non-sinusoidal waveforms common in variable-speed drives and electronic ballasts. Battery life during continuous logging will depend on backlight usage and the selected sampling interval.
