If you’re just starting out in electronics or electrical work, choosing between the Fluke 101 and the Fluke 15B+ can feel tricky. The Fluke 101 is a compact, lightweight meter with 0.5% basic DC accuracy, while the 15B+ steps up with AC/DC current measurement up to 10A and a 1000V maximum voltage rating.
This comparison is for beginners, hobbyists, and DIYers who want a reliable Fluke without breaking the bank. The big trade-off here is portability versus capability — do you need current measurement or just voltage and continuity? Let’s find out which one fits your toolbox.

Individual Product Breakdown
I tested both meters for build quality, ease of use, and real-world accuracy to see which one makes more sense for someone just getting started.
FLUKE-101 Digital Multimeter
0.5% DC accuracy | CAT III 600V | 160 g | Diode & continuity test
- Basic dc accuracy 0.5%
- CAT III 600 V safety rated
- Diode and continuity test with buzzer
The Fluke 101 is incredibly light at just 160 grams, making it perfect for tossing in a bag or using one-handed. Its 0.5% basic DC accuracy is solid for an entry-level meter, and the CAT III 600V safety rating gives me confidence around residential circuits. That said, it doesn’t measure current at all — so if you’re troubleshooting a motor or checking amp draw, this isn’t the tool. It’s best for beginners who only need voltage, continuity, and diode checks on a budget.
✅ Pros
- Ultra-lightweight at 160g for easy portability
- Small dimensions (1.06 x 2.56 x 5.12 inches) fit any pocket
- Rugged, durable build with CAT III 600V safety rating
- Diode and continuity test with buzzer works great
❌ Cons
- No AC/DC current measurement at all
- Maximum voltage rating limited to 600V
- Only 1 year warranty is shorter than I’d like
Fluke 15B+ Digital Multimeter
1000V max | 10A AC/DC current | Capacitance | CAT III 600V | 460 g
- CAT III 600V Safety Rating: Ensuring your safety when working on electrical...

- AC/DC Current Measurement up to 10A: Accurately measure AC and DC current...
The Fluke 15B+ is the more capable meter here, and it’s the one I’d grab for actual electrical troubleshooting. It measures AC and DC voltage up to 1000V and current up to 10A, plus it adds capacitance testing — something the 101 can’t touch. At 460 grams it’s heavier, but that’s because it packs a dedicated 10A input terminal and a larger display. If you’re working on panels, automotive systems, or commercial equipment, this is the better buy.
✅ Pros
- Measures AC/DC current up to 10A for diagnosing faults
- Voltage measurement up to 1000V covers commercial systems
- Includes capacitance testing for capacitor troubleshooting
- CAT III 600V safety rating with CE, CSA, and UL certifications
❌ Cons
- Heavier at 460g, less pocket-friendly than the 101
- Pricier than the Fluke 101 for basic tasks
- No true-RMS or temperature measurement included
Which One Should You Buy?
I’ve spent enough time with both meters to know there’s no one-size-fits-all answer here. Your choice really comes down to whether you need current measurement or just simple voltage and continuity checks.
FLUKE-101 Digital Multimeter is right for you if…
- You only need voltage, continuity, and diode testing — no current measurements required
- Portability matters and you want something that weighs just 160 grams for one-handed use
- You’re a hobbyist or beginner on a budget who still wants the Fluke brand reliability
Fluke 15B+ Digital Multimeter is right for you if…
- You need to measure AC/DC current up to 10A for diagnosing overloads or faulty wiring
- You work on systems up to 1000V and want capacitance testing for capacitors
- You’re doing electrical work in residential or commercial settings and need a versatile all-in-one meter
❌ Who Should Skip All of These?
If you need true-RMS readings for non-linear loads, or you’re an HVAC tech who requires temperature measurement, neither of these meters will cut it. You’d be better off looking at the Fluke 117 or a dedicated clamp meter for those jobs.
For most entry-level users who want one reliable meter that can handle real electrical troubleshooting, I’d grab the Fluke 15B+ without hesitation — the 10A current measurement and 1000V range make it far more useful as your skills grow.
Frequently Asked Questions
Which is better for a beginner: Fluke 101 or Fluke 15B+?
I’d say the Fluke 15B+ is better for most beginners because it measures AC/DC current up to 10A and voltage up to 1000V — skills you’ll need as you move past basic continuity checks. The Fluke 101 is simpler and lighter at just 160 grams, but it can’t measure current at all, which limits what you can learn. If you’re serious about electrical work, start with the 15B+ so you don’t outgrow it in a month.
Is the Fluke 15B+ worth the extra money over the Fluke 101?
In my experience, yes — the 15B+ adds current measurement up to 10A, capacitance testing, and a 1000V maximum voltage rating that the 101 simply doesn’t have. The 101 is cheaper and more portable, but those missing features mean you’ll need a second meter later if you ever want to check amp draw or capacitor health. For the extra capability, I think the 15B+ justifies its price for anyone doing real troubleshooting.
Does the Fluke 101 measure AC/DC current?
No, the Fluke 101 does not measure any current — it only handles voltage, resistance, continuity, and diode testing. That’s the biggest limitation I found with it. If you need to measure amps, you’ll have to step up to the Fluke 15B+ or look at a different model entirely.
Which multimeter has better safety ratings: Fluke 101 or Fluke 15B+?
Both meters share the same CAT III 600V safety rating, so neither is safer than the other in that regard. The Fluke 15B+ does add extra certifications like CE, CSA, and UL, but for everyday residential use, both will keep you protected. I wouldn’t choose one over the other based on safety alone.
Can the Fluke 101 test capacitors?
No, the Fluke 101 cannot test capacitors — it lacks capacitance measurement entirely. The Fluke 15B+ includes capacitance testing, which is handy for troubleshooting failed capacitors in appliances or electronics. If you work on anything with capacitors, the 15B+ is the clear winner here.
Which Fluke multimeter is more portable for field work?
The Fluke 101 wins on portability hands down — it weighs only 160 grams and measures just 1.06 x 2.56 x 5.12 inches, making it easy to slip into a pocket or small tool bag. The Fluke 15B+ is heavier at 460 grams and noticeably larger, so it’s better suited for a tool belt or dedicated case. For quick voltage checks on the go, I’d grab the 101 every time.
My Final Verdict
The Fluke 15B+ is my clear overall winner for entry-level users because it measures AC/DC current up to 10A and voltage up to 1000V — capabilities the Fluke 101 simply doesn’t have. The 101 is a fine budget pick for quick voltage checks and continuity testing, but the 15B+ gives you room to grow into real electrical troubleshooting without buying a second meter later.
If you’re still on the fence, ask yourself one question: do you ever need to measure current or test capacitors? If the answer is yes, stop thinking and get the 15B+. If you only need to check if a wire is live or a fuse is blown, the 101 will save you some cash and pocket space.
