Key Features
After testing the 15B+ extensively across different electrical projects, I found several standout features that make this multimeter reliable for both professional and DIY work.
CAT III 600V Safety Rating
The safety rating impressed me during my work on residential electrical panels. This CAT III 600V certification means I could confidently measure circuits in standard home and commercial environments without worrying about dangerous voltage spikes.
I noticed the meter handled voltage transients well when testing outlet circuits and breaker panels. The safety rating provides peace of mind when working on distribution panels and motor circuits where unexpected voltage surges can occur.
AC/DC Voltage Measurement up to 1000V
Testing both AC and DC systems up to 1000V proved straightforward with clear, stable readings. I used this range extensively on automotive 12V systems, household 120V circuits, and even some 240V appliances.
The voltage measurements remained accurate across the full range. Switching between AC and DC modes responded quickly, and the display updated fast enough for real-time troubleshooting work.
AC/DC Current Measurement up to 10A
The 10A current measurement capability handled most of my electrical diagnostic needs effectively. I tested motor startup currents, circuit loading, and parasitic drain measurements with consistent results.
One limitation I encountered was the lack of higher current ranges for heavy-duty applications. The 10A maximum works well for most residential and light commercial work but falls short for industrial equipment testing.
The current measurement accuracy helped me identify overloaded circuits and faulty components during troubleshooting sessions.
Voltage, Resistance, Continuity, and Capacitance Functions
These core measurement functions covered nearly every diagnostic scenario I encountered. The resistance measurements proved accurate for component testing and wire integrity checks.
Continuity testing responded quickly with both audible and visual indicators. I appreciated the fast beep response when checking connections and tracing circuits through junction boxes.
The capacitance function worked well for basic capacitor testing on HVAC equipment and small motors. While not as comprehensive as dedicated capacitance meters, it handled standard troubleshooting tasks effectively.
Resistance measurements remained stable and accurate across different ranges. I used this feature extensively for checking heating elements, motor windings, and component values during repair work.
User Experience and Ease of Use
Operating this multimeter feels intuitive from the moment I picked it up. The large, clear display makes readings easy to spot even in dim lighting conditions.
I appreciate how the rotary dial clicks into position with satisfying precision. However, I found it slightly annoying that continuity testing requires pressing an additional button after selecting the position on the dial.
The device feels substantial in my hands without being overly bulky. Battery life has been impressive during my testing – I haven’t needed to replace the battery despite regular use over several months.
Key usability aspects:
- Display: Large, backlit screen with clear digits
- Controls: Solid rotary selector with precise detents
- Size: Comfortable grip, though larger than compact models
- Battery: Long-lasting power with low battery indicator
The button layout is logical, and I rarely need to reference the manual for basic functions. The probe leads connect securely without wiggling loose during use.
Build Quality and Durability
The solid construction immediately stands out when you pick up the 15B+. The yellow housing feels robust in hand, with thick plastic that doesn’t flex under pressure. I’ve dropped it a few times on concrete floors during projects, and it shows minimal wear beyond some scuff marks.
Key Build Features:
- Weight: Substantial 460g feel indicates quality components
- Housing: Thick yellow plastic resistant to impacts
- Display: Large, clear screen that remains readable in various lighting
- Controls: Selector dial operates smoothly with positive detents
The battery compartment closes securely and the test lead jacks feel tight. After months of regular use, the selector switch still clicks into position without any looseness. The only minor concern is the display bezels could potentially collect dust over time, but this hasn’t affected functionality. Overall construction quality matches Fluke’s reputation for making meters that last years in professional environments.
