Fluke 117 Digital Multimeter - Accurate True RMS Readings

In this review the Fluke 117 Digital Multimeter is evaluated as a compact, professional tool for electricians and technicians who need reliable, repeatable measurements on commercial and residential jobs. The single biggest reason to buy is its combination of integrated non-contact voltage detection and AutoVolt/LoZ low impedance mode, which together speed troubleshooting and prevent misleading ghost voltage readings in live circuits. For anyone who values accuracy and one-handed operation on the job, the 117 is a practical investment.

Key Features

• Non-contact voltage detection: VoltAlert technology lets users verify the presence of AC voltage without probes, saving time when scanning outlets, switches and conductors.
• AutoVolt automatic selection: The meter switches between AC and DC automatically, reducing setup errors and keeping workflow smooth between different measurements.
• Low input impedance (LoZ): The LoZ mode prevents false readings from ghost voltage, giving electricians confidence in live-circuit diagnostics.
• True RMS measurement: Accurate readings on non-linear loads make the 117 more trustworthy for modern electronic equipment and variable-speed drives.
• Large white LED backlight: A bright backlight helps when working in poorly lit panels or crawlspaces, improving readout visibility.
• Long battery life: Typical battery life around 400 hours without backlight keeps the meter on the job through extended use.

Who It's For

The Fluke 117 is best for electricians, maintenance technicians and facility engineers who work in commercial buildings, schools and hospitals and need a durable, accurate multimeter with non-contact voltage detection and reliable low-impedance measurements. Its true RMS capability and compact ergonomics suit those who move between jobsites and want a professional instrument that can be used one-handed.

Less suitable are hobbyists who only need basic continuity checks or occasional voltage reads and want the lowest-cost option; also, users requiring an expanded range of advanced bench measurements or temperature logging should look at meters with those dedicated functions.

Pros & Cons

Pros

• Built-in non-contact voltage sensor speeds safety checks and initial diagnostics.
• AutoVolt and LoZ reduce setup mistakes and false ghost voltage readings on live wiring.
• True RMS delivers accurate measurements on modern, non-linear loads used in commercial settings.
• Robust battery life and a useful LED backlight for dim work environments.

Cons

• The 117 focuses on electrical field service tasks and omits some advanced bench features such as temperature or extended mA ranges that specialized users might need.
