Fluke 107 Review: Overview
The Fluke 107 is a compact and reliable digital multimeter designed for electricians, technicians, and DIYers who need a dependable tool for general-purpose electrical measurements. Positioned above the Fluke 101 and Fluke 106 in Fluke’s compact series, the 107 stands out with its backlit display, magnetic hanging strap, frequency measurement, duty cycle testing, and capacitance function.
Despite its small size, the Fluke 107 offers many of the essential functions found in larger digital multimeters. It measures AC/DC voltage and current, resistance, capacitance, frequency, and duty cycle. It also includes continuity and diode testing.
The meter is particularly useful for everyday electrical troubleshooting, where portability and simple operation are more important than advanced diagnostic features.
However, the Fluke 107 is not a True RMS multimeter. It uses average-responding AC measurements, making it better suited for ordinary electrical circuits than equipment with heavily distorted AC waveforms.

Fluke 107 In-Depth Review
While the Fluke 107 is marketed as a pocket multimeter, it’s slightly larger than some ultra-compact models. At approximately 5.6 inches tall, it fits comfortably in one hand and takes up very little space in a toolbox.
With the test leads connected, carrying it in a shirt pocket may be less convenient. However, its compact design and useful measurement functions make it a practical everyday tool.
The Fluke 107 digital multimeter is suitable for general electrical troubleshooting, including checking batteries, testing circuits, measuring resistance, and identifying continuity problems.
Its frequency and duty cycle functions also make it more versatile than the Fluke 106.
However, the meter lacks dedicated milliamp and microamp current ranges. This limits its usefulness for precision electronics, where measuring very small currents is often necessary.
The Fluke 107 uses automatic ranging, making operation straightforward for beginners. Continuity testing is also convenient, with an audible alert that helps users check connections without constantly watching the screen.
Fluke 107 Accuracy and Specifications
The Fluke 107 offers dependable accuracy for general-purpose electrical measurements. Its 6000-count display provides enough resolution for most everyday testing tasks.
The following specifications use the manufacturer’s accuracy format: ±(% of reading + digits). These values apply under specified operating conditions and the stated calibration interval.
| Measurement | Range | Accuracy | Resolution |
|---|---|---|---|
| AC Voltage (40–500Hz) | 6V / 60V / 600V | ±(1.0% + 3) | 0.001–0.1V |
| AC Millivolts | 600mV | ±(3.0% + 3) | 0.1mV |
| DC Voltage | 6V / 60V / 600V | ±(0.5% + 3) | 0.001–0.1V |
| AC Current (40–200Hz) | 4A / 10A | ±(1.5% + 3) | 0.001–0.01A |
| DC Current | 4A / 10A | ±(1.5% + 3) | 0.001–0.01A |
| Resistance | 400Ω to 40MΩ | ±(0.5% + 2) on several ranges; up to ±(1.5% + 3) | 0.1Ω–0.01MΩ |
| Capacitance | 50nF to 1000µF | ±(2.0% + 5) or ±(5.0% + 5), depending on range | 0.01nF–1µF |
| Frequency | 10Hz to 100kHz | ±(0.1% + 3) | 0.01Hz–0.1kHz |
| Duty Cycle | 1% to 99% | 1% typical under specified conditions | 0.1% |
| Diode Test | 2V | 10% | 0.001V |
These specifications make the Fluke 107 suitable for routine electrical troubleshooting. However, AC accuracy is specified for sinusoidal waveforms within the applicable frequency limits.
For testing variable-frequency drives or heavily distorted AC signals, a True RMS meter will generally provide more dependable results.
Build Quality
Although the Fluke 107 is manufactured in China, it maintains the solid construction expected from Fluke’s compact multimeter range.
The housing feels sturdy, while the rotary dial and buttons are designed for everyday use. Its compact shape makes it easy to hold and carry, especially when working in restricted spaces.
The meter does not have a traditional fold-out kickstand. Instead, the included SmartStrap magnetic hanging accessory allows users to attach it to suitable metal surfaces or support it at a viewing angle.
This is particularly useful when both hands are needed to position the test probes.
The supplied TL75 test leads have flexible cables, secure shrouded banana plugs, and durable probe tips.
Battery replacement is straightforward through the rear compartment, which is secured with a screw.
Display and Interface
The Fluke 107 features a 6000-count backlit LCD that updates approximately three times per second.
The backlight is one of its biggest advantages over the Fluke 106. It makes the display easier to read in dimly lit workshops, electrical cabinets, and other working environments.
Numbers are clear under normal viewing conditions, although contrast may decrease when the screen is viewed from an extreme angle.
The rotary selector provides access to the main measurement functions. Clearly labeled buttons handle additional features such as data hold and function selection.
Frequency and duty cycle measurements are available through the appropriate measurement settings.
Overall, the interface is simple enough for beginners while still offering useful functions for experienced technicians.
Battery and Power Management
The Fluke 107 operates on two AAA batteries, which are inexpensive and easy to replace.
Fluke specifies a minimum battery life of approximately 200 hours under defined operating conditions. Frequent use of the display backlight may reduce actual battery life.
The meter also includes automatic power management to help prevent unnecessary battery drain.
After approximately 20 minutes of inactivity, the meter automatically switches off.
For users who occasionally forget to turn off their multimeter, this feature is particularly convenient.
Safety and Input Protection
The Fluke 107 is designed with electrical safety in mind. It carries a CAT III 600V measurement category rating and meets the applicable IEC 61010 safety requirements.
Its main safety features include:
- 11A, 1000V fast-acting fuse protecting the current input.
- Manufacturer-specified overvoltage protection.
- Maximum voltage rating of 600V between a terminal and earth ground.
- Shrouded input connections for compatible test leads.
- IP40 enclosure rating for protection against certain solid objects.
The CAT III 600V rating makes the meter suitable for appropriately rated electrical measurements when used by qualified individuals following proper safety procedures.
However, a safety rating does not eliminate electrical hazards. Always inspect the meter and leads before use, use the correct input terminals, and follow the manufacturer’s instructions.
When measuring current, the meter must be connected correctly in series with the circuit. Never connect the current input directly across a voltage source.
The manufacturer also specifies a limited duty cycle for measurements at 10A. Avoid exceeding the permitted measurement duration.
