First Impressions & Unboxing

I received the AstroAI AM33D Multimeter on April 3, 2025. The package was a simple, sturdy cardboard box, with no unnecessary frills. As I carefully opened the box, I immediately noticed that everything was neatly organized and well-protected. There were no loose items or messy packaging, which instantly gave me confidence in the brand’s attention to detail.

The multimeter was wrapped securely in a layer of plastic, with a custom seal ensuring the device hadn’t been tampered with. The seal was intact, which provided peace of mind, confirming the authenticity of the product. Alongside the multimeter, the test leads were neatly coiled and secured with a rubber band, ready to be plugged in and used right out of the box. The user manual was tucked neatly in the back of the box, printed clearly with concise instructions and important safety notes.

When I picked up the AstroAI AM33D, it immediately felt light yet solid. The build quality was impressive, and the silicone cover added a layer of protection against drops or shocks, which was reassuring, as I tend to work in environments where the multimeter could easily be knocked around.

One of the first things I noticed was how easy it was to locate the yellow backlight button, which is crucial for testing in low-light conditions. Without even reading the manual, I instinctively pressed the button to check the display, and it lit up instantly, providing clear and readable numbers. This was a quick win for me, especially since I often perform tests in places like basements or behind furniture, where lighting can be an issue.

The real highlight of the unboxing was the large, backlit LCD display. The screen was bright and easy to read, even in dim conditions. I could see the readings clearly without any strain, which I greatly appreciated, considering I often have to read small numbers in tight spaces like car engine bays or electrical panels.

What’s Included:

1 Multimeter
1 Test Leads

Button Functions on the AstroAI AM33D

Using the AstroAI AM33D feels straightforward even in fast-paced testing environments. It keeps things simple with just two main buttons each one serving a dual purpose to boost convenience and accuracy during use.

HOLD Button – I use the HOLD button to freeze the reading on the display. It comes in clutch when I’m trying to record a value but can’t look at the screen immediately especially when I’m reaching behind a panel or crouched in a tight spot.
Backlight Button (Yellow Button on Right) – This button is all about visibility. A quick press turns on the backlight, making the LCD readable in dim areas like basements or under cabinets. It’s small, but it makes a big difference when I’m working without natural light.
