Fluke | 117 Compact Digital Multimeter 600V | CAT III True-RMS
The Fluke 117 is a compact True-RMS digital multimeter rated CAT III 600 V, built for electricians working on commercial and residential installations. The 117 measures AC and DC voltage, resistance, continuity, frequency, and capacitance, and captures minimum, maximum, and average readings over time. It carries integrated non-contact voltage detection and an automatic AC/DC voltage selector, paired with a 6,000-count backlit display. The meter ships with a TL75 test lead set, a protective holster, and a user manual.
Fault finding on a live site means confirming a conductor is dead before work starts, often with a separate volt stick in hand. Ghost voltage on long cable runs can throw a false reading and send a sparky chasing a fault that is not there. The Fluke 117 answers both with integrated non-contact voltage detection and a selectable low-impedance mode that drops phantom voltage from the reading. Accurate measurement across both low-voltage and extra-low-voltage work keeps one meter on the tools instead of two.
For a sparky on the job, the 117 covers the daily round from one tool: voltage, continuity, resistance, frequency, and capacitance. AutoVolt sets AC or DC for you, so the reading appears without switching ranges between tests. The 6,000-count backlit display stays readable in a dark switchboard, and the min, max, and average capture flags intermittent faults a single reading would miss. A true-RMS movement reports accurate figures on the distorted waveforms common on circuits with electronic loads.
Features
- True-RMS measurement — reports accurate AC voltage and current on distorted and non-linear waveforms, not just clean sine waves.
- CAT III 600 V rated — certified to IEC 61010 for measurements on fixed installations and distribution wiring up to 600 V.
- Non-contact voltage detection — the built-in VoltAlert sensor gives a fast go/no-go live check without touching a conductor or reaching for a separate volt stick.
- AutoVolt AC/DC selection — the Fluke 117 detects whether the voltage is AC or DC and displays the correct reading automatically.
- Selectable low-impedance mode — LoZ loads the circuit to clear ghost voltage from long parallel cable runs and prevent false readings.
- 6,000-count backlit display — stays legible in dark switchboards and roof spaces, updating four times per second.
- Capacitance and frequency ranges — measures capacitors and signal frequency alongside voltage, resistance, and continuity from the one meter.
- Min, max, and average capture — records measurement extremes over time to catch intermittent drops and surges a single reading would miss.
- 10 A current range — measures AC and DC current to 10 A through a fused input, with a maximum resolution of 1 milliamp.
- IP42 rated housing — sealed against dust and dripping water for protection on site, though the 117 is not submersible and not weatherproof.
- 9 V battery operation — runs around 400 hours on a single 9 V alkaline cell, so the meter stays usable through long stretches without backlight.
- Supplied ready to use — the Fluke 117 includes a TL75 test lead set, a protective holster, and a user manual in the box.
Where to use
- Commercial fit-outs — the Fluke 117 suits testing and fault finding across offices, retail, and other commercial buildings on a CAT III 600 V system.
- Hospitals and schools — handles routine verification and diagnostics in institutional buildings where downtime needs to stay short.
- Domestic service work — checks power points, lighting circuits, and appliance faults during callouts and switchboard upgrades.
- Switchboard testing — confirms voltage presence, polarity, and continuity at the board, with the backlight covering dim meter cupboards.
- Live-dead-live testing — the non-contact detector and direct voltage ranges support proving a circuit dead before work begins.
- Capacitor and motor checks — the 117 measures capacitance on motor-run and HVAC capacitors to confirm a suspect part before replacement.
- Apprentice and training use — clear ranges and automatic selection make the meter a practical first instrument on the tools.
The Fluke 117 is rated for CAT III 600 V and is not suitable for CAT IV service-entrance work or for measuring circuits above 600 V. It carries an IP42 housing, so it is not weatherproof and must be kept out of rain, submersion, and heavy wash-down areas.
