Fluke 289 True-RMS Industrial Multimeter - Fluke-289
The Fluke 289 True-RMS Industrial Logging Multimeter is the highest-capability handheld multimeter inthe Fluke professional line, a premium instrument built for MRO technicians, plant engineers, andelectronics troubleshooters who need measurement, data logging, graphical analysis, and wirelessconnectivity in a single package. Its 50,000-count dot-matrix display with TrendCapture graphicaltrending, 14x on-screen zoom, real-time clock timestamping, and storage for up to 15,000 eventstransforms routine electrical measurement into documented data collection. For aviation maintenanceprograms that require traceability and for MRO facilities tracking electrical system degradation overtime, the 289 is the instrument that closes the gap between a handheld multimeter and a dataacquisition system.
Key Features
- TrendCapture Graphical Display with 14x Zoom: The 289 displays a real-timetrend graph of any measurement directly on the instrument screen, no PC required. The 14x zoomfunction magnifies any segment of the trend history for detailed analysis of transients, load changes,and intermittent events. MRO technicians use this to document motor current startup profiles, voltagesag behavior during load application, and waveform envelope trends that would be invisible on anumeric display.
- 15,000-Event Data Logger with Timestamps: Stores up to 15,000 measurement eventswith automatic real-time clock timestamps. Adjustable recording intervals (percentage-based thresholds)capture only significant changes, maximizing storage efficiency during long monitoring sessions.Download via IR optical port to FlukeView Forms software for professional report generation.
- 50,000-Count Display (4.5-Digit Precision): The 50,000-count resolution is 8xhigher than a standard 6,000-count meter. On a 200V AC circuit, this means resolution to 0.001V, critical for detecting small voltage imbalances between motor phases, identifying voltage drop acrossconnections, and documenting compliance with specification limits.
- 50Ω Low Resistance with 1mΩ Resolution: The 289 includes a 50Ω measurement rangewith 1 milliohm resolution, specifically designed for motor winding resistance measurement. Thisallows precise winding-to-winding balance checks on three-phase motors, identification of shorted turnsfrom resistance asymmetry, and compliance with manufacturer resistance specifications in milliohms.
- Expanded Capacitance to 100mF: The 289 measures capacitance up to 100 millifarads(vs 10,000µF on the 87V), covering large motor run capacitors, power factor correction bank capacitors,and large filter capacitors in industrial power supplies that exceed the range of standard meters.
- LoZ Low-Impedance Mode: Like the 117, the 289 includes a low-impedance mode forghost voltage elimination in industrial panels with dense, parallel conductor routing. Essential forconfirming true de-energization in MCC (motor control center) maintenance.
- Low-Pass Filter for VFD Measurement: The same selectable low-pass filter found inthe 87V blocks VFD carrier frequencies for accurate fundamental voltage and frequency readings atmotor terminals. The 289 is equally capable as the 87V for drive troubleshooting with the addedbenefit of logging drive output over time.
- Fluke Connect Compatible via ir3000 FC: With the optional ir3000 FC wirelessconnector, the 289 transmits measurements via Bluetooth to the Fluke Connect mobile app for real-timeremote monitoring, cloud data storage, and ShareLive video call collaboration with remote experts.
- Temperature to 1350°C: Extended thermocouple range to 1350°C (vs 1090°C on the87V) covers high-temperature industrial applications including furnaces, kilns, boilers, andhigh-temperature bearing monitoring.
- Auto Hold and Display Hold: Auto Hold captures stable readings automatically, useful for measuring in confined spaces where the display isn't visible until the probe is withdrawn.Combined with TrendCapture, this enables one-handed unattended monitoring.
Technical Specifications Overview
The 289 measures AC/DC voltage to 1000V (0.025% DC accuracy), AC/DC current to 10A, resistance to50MΩ with a 50Ω low range, capacitance to 100mF, frequency beyond 1MHz, and temperature to 1350°C.Its 50,000-count display and real-time logging put it above the 87V and 287 in the Fluke lineup.The 289 is the choice when measurement data needs to be logged, trended, documented, and retrieved, where the 87V captures a single reading, the 289 captures the history.
MRO & Industrial Data Acquisition Applications

QUESTIONS & ANSWERS
Yes, with conditions. The Fluke 289 is a precision measurement instrument suitable for inclusion in a Part 145 repair station's calibrated tool control program. This listing includes a traceable calibration certificate with data, satisfying the initial calibration documentation requirement at receiving. Annual or interval-based recalibration will still be required per your station's quality manual, but the 289 arrives with the paperwork in order to enter your tool control system on day one.
Yes. The Fluke 289's 0.025% basic DC accuracy and 1 µV DC mV resolution make it well-suited for verifying regulated 28VDC aircraft bus voltage against AMM tolerances. It handles both the steady-state check and the dynamic logging use case — TrendCapture can monitor bus voltage behavior across an entire ground run or taxi sequence and flag anomalies without requiring a technician to stand by the meter.
The Fluke 289 includes a selectable AC filter (Smoothing mode) specifically designed to address PWM noise — a known challenge when measuring actuator motors, flight control surface drives, and variable-frequency systems in modern aircraft. Standard True-RMS meters without this filter produce inflated or unstable readings on PWM outputs because they respond to high-frequency switching components rather than just the fundamental signal. The 289's 100 kHz bandwidth combined with the smoothing filter gives technicians a readable, meaningful measurement rather than a noisy one.
Yes. The Fluke 289 includes a dedicated two-terminal 50Ω low-resistance range with 1 mΩ resolution and a 10 mA source current, designed specifically for measuring and comparing winding resistances on small motors. This is directly applicable to landing gear actuators, flap drive motors, and other electro-mechanical aircraft components where winding imbalance or degraded insulation shows up as a resistance difference between phases.
The hardware is identical. The version with a calibration certificate (also listed as Fluke 289 CAL) includes a traceable certificate of calibration with measurement data from Fluke's calibration lab. This documentation confirms the specific unit's performance against NIST-traceable standards at the time of calibration. For general commercial use the standard unit is sufficient, but for FAA repair stations, ISO 9001 operations, military/DLA maintenance contracts, or any environment where calibrated tool traceability is audited, the CAL version is the correct procurement choice.
The Fluke 289 supports recording sessions up to approximately 200 hours in length, storing up to 10,000 events. For extended unattended use — long soak tests, overnight monitoring, or multi-shift tracking — it can be powered from an AC line adapter rather than batteries, eliminating the risk of a logging session ending due to battery drain. This makes it practical as a semi-permanent monitoring station on a test bench or tied to a specific system during a maintenance investigation.
Yes. This listing includes the Fluke 289 with a traceable calibration certificate with data, making it suitable for ISO 9001 environments, FAA repair stations, and government/DLA procurement requirements where measurement traceability documentation is required.
TrendCapture is the Fluke 289's on-board data logging and graphical review function. It stores up to 10,000 recorded events and plots them as a trend graph directly on the meter's display — no PC required. A 14x zoom function allows detailed analysis of any captured anomaly in the logged session.
The Fluke 289 measures up to 10 A continuous AC or DC current, with a 20 A burst capacity for up to 30 seconds.
Yes. The selectable AC filter (Smoothing mode) and 100 kHz True-RMS bandwidth allow accurate measurement on pulse-width modulated (PWM) motor drive outputs, where standard multimeters produce unreliable readings due to high-frequency noise and bandwidth limitations.
