What a deal On a Digital Voltmeter ?

I have one of these meters in the MH. But I think you can't beat the free HF mutimeters. They are off as Oldmen said but they can be adjusted inside by a small pot if you have a Fluke or another good meter that you trust. I have left one out in the rain overnight, ruined another while checking amperage, and melted another with gas while working on my generator fuel pump. I would have been sick if they were Fluke meters, but because the were free I saved the batteries and leads for replacement parts for my working meters. Once you know what the limitations are and can adjust for it they are great meters.
