First Impressions & Unboxing

I unboxed the Amprobe AM-520 Digital Multimeter on April 13, 2025, and I immediately got a sense that this was a serious piece of equipment. After checking it out, I couldn’t wait to dive into the Amprobe AM-520 review. The packaging wasn’t flimsy, none of that cheap cardboard stuff. The box was sturdy, similar to what you’d expect from a fluke-multimeter. I could tell Amprobe had taken extra care to ensure the multimeter would arrive in perfect condition.

what I pulled out:

✔ AM-520 Multimeter – Solid, well-balanced, and just the right weight for durability.
✔ Test leads – Thick insulation, secure, and durable.
✔ Type-K Probe – Accurate temperature readings right away.
✔ Velcro strap – Handy for organizing the test leads.
✔ Carrying case – Compact and durable, perfect for storage.

When I held the AM-520, the rubberized casing immediately gave me a secure grip. I could already tell it was designed to withstand a drop or two (though I’m not planning to test that!). The buttons were firm and responsive, and I didn’t feel any cheap plastic or loose components. While testing, I also compared it to the amprobe-am-500.

Of course, I powered it up right away. The AM-520’s backlit LCD screen was crisp and clear, even in the dim lighting of my workspace. That’s something I’ve definitely missed with other, cheaper models.

Button Functions on the Amprobe AM-520

When I got my hands on the Amprobe AM-520, I knew it was built with HVAC techs like me in mind. After reading the Amprobe AM-520 review, I could tell the buttons weren’t just there for show they’re intuitive and make a real difference when I’m out troubleshooting in the field.

• SELECT Button
  This yellow button is the one I reach for when I need to toggle between AC and DC. Instead of spinning the dial around each time, I just press SELECT to switch modes. It’s especially handy when I’m juggling voltage readings and need to stay efficient.
• HOLD / Backlight Button
  I’ve used this countless times while balancing the meter in tight panels. A quick tap freezes the current reading, giving me time to jot it down or snap a photo. Holding it for a couple of seconds turns on the backlight, which has saved me more than once in poorly lit basements or behind HVAC units.
• REL (Relative Mode) Button
  This one’s perfect for comparing changes over time. I press REL to zero out the display, and every measurement after that shows the difference from that baseline. Whether I’m checking voltage drops or resistance shifts, this feature keeps my readings focused.
• RANGE Button
  By default, the meter auto-ranges, but sometimes I prefer manual control. I press the RANGE button repeatedly to cycle through fixed ranges and hold it down to jump back into auto mode. It gives me better command when I need precision.
• MAX/MIN Button
  This is my go-to when I’m tracking fluctuating signals. With MAX/MIN active, the meter logs the highest and lowest values, so I don’t miss a spike. I let it run while I check connections, and it saves the extremes for review.
• Flashlight Button
  Tucked on the side is a tiny but mighty flashlight button. I hit it anytime I’m working in dark spaces like crawl areas or equipment closets. It’s saved me from fumbling with a separate torch, especially when both hands are busy.
