Fluke 180 Series Multimeter Repair (187, 189)

Status: Discontinued — Replaced by 287 / 289

Overview

The Fluke 187 and 189 were Fluke’s first true-RMS logging multimeters, bridging the gap between standard handheld DMMs and the current 280 Series. The 189 offered 50,000-count resolution, Min/Max/Avg recording, and TrendCapture-style logging before the 289 existed. The 187 provided the same measurement engine with 20,000-count resolution. Both models were rated CAT III 1000 V and remained popular in industrial and lab environments for years after discontinuation. The 287 and 289 are their direct replacements.

Common Fluke 180 Series Failures We Repair

LCD display degradation — fading, missing segments from age
Rotary switch contact wear from extended use
Input protection circuit aging after years of service
Battery compartment corrosion
IR communication port failure affecting data download
Internal EEPROM failure causing calibration data loss

Our technicians perform component-level diagnostics on every Fluke 180 Series unit. We don’t just replace boards — we identify and repair the specific failed components, saving you the cost of full module replacements when possible.

Calibration

Every Fluke 180 Series repair includes NIST-traceable calibration. We verify all measurement functions — DC/AC voltage, DC/AC current, resistance, and any additional functions — against our reference standards and provide a detailed calibration certificate documenting measured performance against the manufacturer’s published specifications.
