DMM question.

Will a cheap (ebay-bought) DMM work for setting my gains? I don't want to spring for an expensive one since this is all it will be used for. Thanks.

Well, yes and no. It will work but it depends on just how accurate you want to get with it. Cheap DMM generally do not have true RMS which allows the DMM to read the effective AC voltage from the outputs. IMO, I would ask around see if a friend has a good one.

Yes, it will be fine just probably not 100% accurate. I've always used cheap ones from Walmart/Harbor Freight/etc
