Build Quality and Portability
One of the strongest reasons to consider the Fluke 107 is its compact design. It is considerably easier to carry around than many full-size industrial multimeters.
The rotary selector is simple to operate, and the digital display provides a clear reading during routine measurements. For technicians who spend much of the day moving between panels, machines, control cabinets, and electrical equipment, this compact format can be convenient.
The meter also includes a built-in battery compartment and uses two AAA batteries. That is useful because replacement batteries are easy to find.
If you are comparing several meters for professional field work, my guide to the best multimeter for electricians covers additional Fluke and competing models for different testing requirements.
Voltage and Current Measurement
The Fluke 107 measures both AC and DC voltage, with voltage measurement up to 600 V. This makes it useful for checking common electrical circuits, control systems, power supplies, and equipment.
The meter also measures DC current up to 10 A. Current measurement should always be performed with the correct test lead connection and meter setting. Incorrectly connecting a current meter across a voltage source can cause a short circuit and potentially damage the instrument or circuit.
For normal troubleshooting, the Fluke 107 provides the basic voltage, current, and resistance functions expected from a professional handheld digital multimeter.

Resistance, Continuity and Diode Testing
Resistance measurement is useful when checking components, wiring, coils, and circuits that are safely de-energized. The Fluke 107 measures resistance up to 40 MΩ.
Continuity testing is another feature that gets frequent use in electrical troubleshooting. A quick continuity check can help identify an open conductor, blown fuse, broken connection, or faulty switch.
The diode test function is useful when checking semiconductor components. It can help technicians assess whether a diode is conducting in the expected direction.
Before performing resistance, continuity, or diode measurements, disconnect the circuit from its power source and verify that it is de-energized.
Capacitance and Frequency Testing
The Fluke 107 also includes capacitance measurement up to 100 μF and frequency measurement up to 100 kHz.
Capacitance testing can be useful when checking certain capacitors used in electrical and electronic equipment. Frequency measurement can help when troubleshooting control signals, power supplies, generators, and other AC or electronic circuits.
These functions make the meter more versatile than a basic voltage tester. However, specialized instruments may be more suitable for applications requiring advanced waveform analysis, high-frequency measurements, or detailed power-quality information.
For electricians building a practical test kit, I recommend comparing the meter's actual functions with your normal work instead of paying for features you may rarely use.
CAT III 600 V Safety Rating
Safety is one of the most important specifications when choosing a multimeter.
The Fluke107 carries a CAT III 600 V measurement category rating. CAT ratings describe the environments and transient conditions for which test equipment is designed when used within its stated voltage limits.
CAT III equipment is intended for measurements in building installations and distribution systems, including fixed equipment and distribution panels within its rating.
However, the CAT rating does not make an unsafe measurement safe. The test leads, meter condition, measurement procedure, PPE, and electrical installation all matter.
As an electrical engineer, I treat the meter's safety category as only one part of the overall measurement process.
Is the Fluke 107 Good for Electricians?
The Fluke107 can be a practical choice for electricians who need a compact meter for general troubleshooting. Its AC/DC voltage, current, resistance, continuity, diode, capacitance, and frequency functions cover many everyday measurements.
Its compact size is particularly useful for technicians who already carry several other tools.
There are, however, situations where a larger or more specialized meter is preferable. Industrial electricians working around demanding motor systems, variable frequency drives, high-energy equipment, or advanced power measurements may need additional functions.
If your work involves frequent field measurements, compare the Fluke 107 with other options in my guide to a multimeter for electricians before deciding.
