Our Testing Experience

First Impressions

When I first got the Amprobe 37XR-A True RMS Digital Multimeter, I was eager to try out its logic test feature. I connected the test leads carefully, and the built-in warning tone helped me avoid putting them in the wrong jacks, which was really handy. The size of the meter felt just right in my hands—not too big or heavy—making it easy to hold while testing different components around the house.

Daily Use

Over the next few days, I used the multimeter for several tasks, including checking inductance and capacitance on some old circuits I was fixing. The logic test to 20 MHz was surprisingly accurate and quick, letting me identify signals without any hassle. I liked how the frequency measurement went up to 40 MHz, which covered everything I needed for my projects. The clear display and 10,000 count resolution made reading values simple, even in less light.

Key Features in Action

The true RMS feature made a big difference when testing AC signals, giving me confidence in the results. The component logic test was my favorite because it helped me quickly check digital signals up to 20 MHz, something I hadn’t tried on other meters before. Also, measuring inductance up to 40 H and capacitance up to 400 microF was a breeze, saving me from switching tools. The input warning tone was a thoughtful safety feature that prevented any accidental mistakes.

Long-Term Performance

After using the Amprobe 37XR-A for a few weeks, it still worked like new. The accuracy stayed consistent, and the battery life seemed solid. The device didn’t feel worn out or sluggish, even after many tests. Overall, it proved to be reliable for both simple and more detailed electronic work, making it a great addition to my toolbox.
