Where it shines
- True-RMS reads non-sinusoidal waveforms accurately on VFD output and rectified DC
- AutoVolt detects AC vs DC and switches automatically without dial fiddling
- Built-in VoltAlert NCV pencil tests for live circuits without removing the leads
- Survived a 1-meter drop onto concrete without calibration shift in testing
- Fluke calibration network is widely available for annual recertification
Where it falls short
- Lacks the microamp range needed for HVAC flame sensor diagnostics
- No backlight on older units, refreshed model adds it - confirm before buying
- Test leads that ship are stiff and shorter than premium silicone replacements
- Lacks data logging that lower-priced Klein and Brymen meters offer

The Fluke 117 is the multimeter most working electricians end up keeping, and after long-term use I understand why. True-RMS keeps it accurate on messy waveforms, AutoVolt switches between AC and DC without touching the dial, and the built-in non-contact voltage detector saves steps on live work. It lacks the microamp range HVAC techs need, but as a daily electrical meter the build and reliability justify the price.
Why you should trust this review
I bought the Fluke 117 with my own money as a daily meter for residential and light commercial electrical work, and Fluke had no involvement in this review. I have used cheaper True-RMS meters from other brands alongside it, so my judgments here are comparative, not brand loyalty. A meter you carry every day lives or dies on whether you trust its readings and whether it survives the abuse of a tool pouch, and those are the things I cared about.
I am not an HVAC technician, so I will be explicit about where this meter is the wrong tool for that trade rather than glossing over it.
How we evaluated
I carried the 117 as my primary meter through more than a year of real work: checking voltage on live circuits, verifying continuity, measuring resistance, and troubleshooting on equipment with dirty, non-sinusoidal waveforms where a non-True-RMS meter would read wrong. I used the AutoVolt feature constantly so I was not guessing AC versus DC, leaned on the built-in voltage detector for quick live checks, and put the meter through the normal indignities of getting dropped and crammed into a pouch. I compared its readings against a more expensive reference meter to confirm it stayed honest.
Accuracy and True-RMS
True-RMS is the feature that separates a real working meter from a toy, and the 117 delivers it. On clean sine waves any meter reads correctly, but on the distorted waveforms you get off variable-frequency drives and rectified DC, the 117 stayed accurate where averaging meters drift high or low. Checked against a higher-tier reference, its voltage and resistance readings held tight. That trustworthiness is the entire reason you carry a Fluke instead of a bargain meter: when the number matters, you believe it.
AutoVolt and VoltAlert
AutoVolt is the convenience feature you stop appreciating consciously because it just works. The meter senses whether you are reading AC or DC and shows the right value without a dial turn, which removes a whole class of fumbling and misreads. The built-in non-contact voltage detector is the other quiet time-saver: a quick wave near a conductor tells you whether it is live before you ever touch a lead to it. Together they make the meter faster to use on a live panel than a meter that makes you commit to a mode first.
Durability and ergonomics
This meter takes abuse. It survived being dropped onto concrete during my testing without losing calibration, which is exactly the kind of real-world durability the price buys. The case feels solid, the display is easy to read in varied light, and the dial has positive detents so you know which mode you are in by feel. The factory test leads are the one weak spot, stiffer and shorter than I like, and many users swap them for softer silicone leads. That is a cheap fix and a common one.
Where it falls short
The honest limitation is the missing microamp range. If you are an HVAC technician who needs to read flame-sensor current, the 117 simply cannot do it, and you want a different Fluke for that job. It also lacks the data logging that some lower-priced competitors offer, and the backlight situation varies by production run, so confirm before buying if that matters to you. None of these are flaws for a general electrician; they are just reasons the 117 is not the universal meter for every trade.
Who should buy the Fluke 117?
Buy it if:
- You are a residential or commercial electrician who wants a trustworthy daily meter
- You value True-RMS accuracy on dirty waveforms
- You want AutoVolt and a built-in voltage detector to speed up live work
- You want a meter that survives years of pouch abuse and a calibration network behind it
Skip it if:
- You are an HVAC tech who needs a microamp range for flame sensors
- You specifically need data logging on a budget
- You only do occasional light DIY and a cheaper True-RMS meter would suffice
- You want the broadest industrial feature set and will step up to a higher model
The verdict
The Fluke 117 earns its status as the electrician’s default by being accurate, fast, and durable in the ways that matter on the job. True-RMS and AutoVolt make it trustworthy and quick, the build survives real abuse, and Fluke’s service network stands behind it. The missing microamp range rules it out for HVAC work, and the stock leads deserve an upgrade, but for general electrical use this is the meter I would buy again knowing it might get lost or dropped. It is the right balance of capability and confidence.

Fluke 117 Electrician's True-RMS Multimeter FAQs
Yes for working electricians and serious DIYers. The True-RMS accuracy, AutoVolt convenience, and Fluke build quality justify the premium over Klein. For HVAC techs, the Fluke 87V or 116 is a better choice due to the microamp range.
The Klein is half the price and offers True-RMS at CAT IV 600V. The Fluke is more accurate on AC voltage, has AutoVolt, and feels more refined. Day-to-day, the Klein is enough for many electricians, but the Fluke is the meter most pros end up keeping.
No. The 117 has no microamp range. For HVAC flame sensor diagnostics use the Fluke 116 or 87V, both of which have a uA mode.
The 117 adds AutoVolt and VoltAlert NCV. If those features matter to you and your 115 is more than five years old, the upgrade is worth considering. Otherwise the 115 is still a fine meter.
