DC Volt Amp Meter

Works fine. Easy to install.

Great product ! Works great, no problems with using it . Check measurements with a multimeter on the Money. so many useful ways to use this having fun

Meter has bright and clear display, but no directions on polarity of ammeter function. Test before installation. You will get a second decimal point on display if polarity is reversed.

Only had it installed for a day now on my lawnmower to find out why my battery is always dead. Very easy to install and wire. I had to reverse the amp pickup on the battery cable, it was showing negative amps, the marking on the pickup was marked wrong. Not a big deal. It works very well. The red volt display is a little hard to read but I'm sure it wasn't designed to be used outside in bright sunlight.

Amazing device. I bought one to test, then bought six more. I attached one per battery in my battery bank so I can easily tell if a terminal fuse is blown and I can see if the amp pull from each battery shows the bank is balanced. I was expecting the accuracy to be just ok, but I was wrong. It is almost perfect. Every battery shows the same voltage value - which they should since they are interconnected, but that shows each device is calibrated correctly at the factory. The current readings are close to what my Victron BMV reports. It's hard to find a device like this that works for DC and up to 100 amps. I'm going to buy an eight to show the current being pulled from the alternator. Build quality is excellent. The devices look nice and they include an extension for the current clamp. I just wish there was a circular version that fit in the standard 1" hole.

Work very well I wish they had a meter that reads 300 amps

A good quality volt/amp meter to read draw/volts on my HF amplifier. Quite accurate in comparison to my fluke meter.

I have two of these. One appears to be working properly but the other is not giving an accurate voltage reading (displayed voltage is 0.5V to 0.7V higher than voltage measured on a multi-meter).There's a procedure for calibrating current reading (which I've done), but nothing for voltage.I'd just return it, but the window has closed and I can't find any support avenue other than a set of self-help steps that don't have anything to say about voltage accuracy.
