In an era where the market is flooded with inexpensive multimeters of questionable quality, Fluke’s decision to enter the budget segment with the 101 model is both bold and necessary. This review will explore every aspect of this instrument, from its build quality and measurement capabilities to its practical limitations and ideal use cases.
Design and Build Quality
Physical Construction
The Fluke 101’s most immediately striking feature is its remarkably compact form factor. Measuring significantly smaller than traditional full-size Fluke multimeters, this device truly lives up to its “pocket portable” designation. The unit’s slim profile is primarily achieved through the elimination of current measurement functionality and the strategic placement of input jacks on the bottom edge rather than the front face.
The construction quality immediately reflects Fluke’s engineering heritage. Despite its budget positioning, the 101 features solid plastic construction that feels substantial in hand. The rotary selector switch operates with the precise, smooth action users expect from Fluke instruments, providing positive detents at each position without any wobble or uncertainty. The pushbuttons exhibit crisp, responsive action with clear tactile feedback.
However, the design is not without compromises. The absence of rubber overmolding or protective holster means the unit will slide around on smooth surfaces, requiring users to prop it up during use. Some reviewers have noted this as a practical limitation, particularly when working on benchtops or in confined spaces where the meter needs to remain stable during extended measurements.
Display and User Interface
The 101 features a clear LCD display with a 6000-count resolution, which represents a significant advantage over many competitors in the sub-$50 price range that typically offer only 4000-count displays. This higher resolution translates to more precise readings and better measurement granularity across all functions.
The display, while clear and easy to read under normal lighting conditions, lacks backlighting – a notable omission that limits usability in dimly lit environments. Several users have specifically mentioned this limitation when working in electrical panels, under dashboards, or in other poorly lit conditions common in electrical troubleshooting scenarios.
An interesting optical phenomenon reported by users wearing polarized sunglasses is display distortion, though this is more a characteristic of LCD technology than a specific flaw of the Fluke 101.
Ergonomics and Portability
The compact design delivers on its promise of true pocket portability. The unit easily fits in shirt pockets, tool pouches, or small compartments in tool bags. This size advantage becomes particularly apparent when working in confined spaces, climbing ladders, or when technicians need to carry multiple instruments.
The bottom-mounted test lead jacks represent both an advantage and a limitation. While this configuration contributes to the compact form factor, it means the unit must be laid flat during use, as it cannot stand upright like traditional multimeters with front-mounted jacks. Users have adapted to this design characteristic, with many reporting they simply lay the meter down during measurements without significant inconvenience.
Technical Specifications and Performance
Measurement Capabilities
The Fluke 101 covers the essential measurement functions required for most basic electrical work:

Users consistently report accuracy that matches more expensive Fluke models, with several technicians comparing readings directly against their professional-grade instruments and finding negligible differences.
Resistance Measurement: Ohms measurement is available across multiple ranges, though some users report slower response times compared to higher-end Fluke models. This slower response is particularly noticeable when testing variable resistances or when quick succession measurements are required.
Continuity Testing: The audible continuity function works reliably, though the response time is not as immediate as professional-grade instruments. For basic continuity checking, this slight delay rarely impacts practical use.
Capacitance Measurement: The inclusion of capacitance measurement capability at this price point is noteworthy, providing additional utility for HVAC technicians and electronics repair specialists.
Notable Limitations
The most significant limitation is the complete absence of current measurement capability. This means no AC or DC current measurement, no amp clamp compatibility, and no inrush current measurement. For many basic electrical tasks, this limitation is not critical, but it does restrict the instrument’s utility for more comprehensive electrical troubleshooting.
The lack of a fuse represents another important consideration. While this design choice helps achieve the aggressive price point and compact form factor, it raises questions about protection during fault conditions. Some users express concern about this omission, particularly those accustomed to fused protection in their primary instruments.
