I came across a small voltmeter/ammeter board on Taobao and decided to order one and give it a try. Turns out I made the right call—but more on that in the review.

Continuing the topic of devices with VFD displays, I want to tell you about a rather interesting product: a fairly accurate ammeter-voltmeter that could come in handy for a hobbyist.

While developing a device for testing and balancing multi-cell battery packs, I needed a multifunction meter. Since I planned to use it together with an electronic load, though, the meter had to be a little unusual. A look at the device, its description and tests, plus a short cautionary tale, after the jump.

I’ve already posted a review of a very similar device once before—the title was almost the same, too. This time, though, the little meter is a bit cheaper, and its quality is definitely no worse than the previous one. So, here’s a quick review of a useful little gadget for electronics hobbyists.

I already reviewed a small voltmeter about three years ago, and now another similar little gadget has landed in my hands. The previous one was more expensive, but it had a separate measurement input and could measure up to 99.9 V. This one is much simpler, but I figured these little meters might still be useful to someone.

Today I'm reviewing a somewhat unusual device. To be honest, I'm not even sure what the right title for this review would be, since this device isn't just a voltmeter, though that's probably the main thing I'm interested in here. This won't be a very long review, partly because the device is rather specialized and partly because there isn't all that much to say about it.
