First Impressions & Unboxing

I unboxed the Amprobe PM51A on April 19, 2025. The package arrived in a compact brown box with Amprobe’s branding and a tamper-proof seal on the side. That small red seal wasn’t just there for show it had a printed batch number and QR code. I scanned it right away to verify authenticity through Amprobe’s website. It matched. That was my first green flag.

Once I broke the seal and lifted the lid, the multimeter sat snug inside a molded cardboard insert Amprobe PM51A Review. No excessive plastic or waste just smart, secure packaging. That insert kept everything locked in place during shipping. I even noticed that the test leads were tied together with a soft velcro strap instead of the usual twist ties, which was a nice touch.

Here’s what I pulled out of the box:
✔ The PM51A unit itself – Slimmer than I expected, barely thicker than my iPhone, and feather-light (roughly 0.3 lbs).
✔ Test leads – Red and black, with flexible insulation that didn’t feel like it’d crack in cold weather.
✔ Battery – Already installed, saving me the hassle of digging through drawers.
✔ Quick guide – Folded neatly, printed in clear, readable fonts with color diagrams—no tiny unreadable text.

As soon as I powered it on (yes, it turned on immediately—no delay), the display came to life. The digits were crisp and clean, though I did notice there’s no backlight, which might be a drawback in low-light situations. Still, in my well-lit workshop, it was easy to read from different angles.

Before running any actual tests, I always inspect build quality. The rotary dial clicked precisely into each function without feeling loose or uncertain. I flipped it from AC voltage to resistance and continuity, just to check the tactile response. Everything felt tight and responsive. No cheap-feeling buttons either each press had a nice, firm snap.

The outer casing is rubberized on the corners, which gives decent grip. I tapped it gently on my workbench a few times (nothing crazy, just a durability check), and it didn’t rattle or show signs of flexing. That tells me Amprobe didn’t cut corners with construction.

All in all, the first few minutes with the PM51A were solid. It’s rare to get something this compact that doesn’t feel compromised. I was already planning which test circuits I’d try it on first—and it definitely earned its spot in my pocket for the week ahead.

Button Functions on the Amprobe PM51A

Despite its pocket-sized frame, the Amprobe PM51A delivers serious functionality — Amprobe PM51A Review. I’ve used it in tight spots and quick jobs, and the button layout makes every second count.

• SELECT Button
  Located just below the display, this button allows me to toggle between alternate measurement functions. For instance, when I set the rotary switch to the voltage position, pressing SELECT switches between DC and AC voltage measurements. Similarly, in the resistance mode, it lets me cycle through resistance, continuity, diode test, and capacitance functions. This feature streamlines the process, eliminating the need to adjust the rotary switch repeatedly.
• HOLD Button
  Also situated below the display, the HOLD button is invaluable when I need to freeze a measurement on the screen. A quick press captures the current reading, allowing me to record or analyze it without the value changing. Holding this button for more than a second activates the MAX HOLD mode, which captures and displays the maximum value detected a feature particularly useful when monitoring fluctuating signals.
