seems accurate.

Ready to use I hooked it up to a 12.8v battery and a 3.8ohm load and compared it to my Fluke DVM. The current reading was accurate to 0.1 amps. Voltage accurate to 0.1V.

Pros
  • Confident
Cons
  • Some bugs

Good device and features.

There were no drawings or diagrams, but they were easy to find on the web. This device works as it should, reading voltage and current. Beautiful blue backlight. Fits perfectly in any swing panel installation.

Pros
  • High-quality assembly
Cons
  • Not everything fits

Looks great, nice blue display.

Looks great! I used it in a box where I built a ham radio transceiver. A beautiful blue display shines through the window, letting me know the status of my battery. Easy to connect, easy to use.

Pros
  • Absolutely amazing!
Cons
  • Frequency

Poor quality good for spares

We like the design and the LEDs are very bright which is good for some applications. We bought 8 at once, 1 didn't work when it arrived and now we have 2 more that died after the first test. So the quality is not as good as initially assumed. Also, the readings are not accurate when we use our calibrated voltmeter, 0.6V difference from the monitor readings.

Pros
  • Great for a small home
Cons
  • Volume

Be careful when installing the meter!

The meter is great for those hard to reach places but the wiring diagrams shown on the product page are tricky. The diagram above shows the correct and safe way to connect the meter to your system. However, the diagram below shows that a positive counter input requires two positive inputs. This can cause injury and possibly a fire. Ignore the diagram below and connect the meter to battery positive, battery negative and the center input grounded to the frame.

Pros
  • This is great
Cons
  • Repair
