Voltmeter ?
I just installed a digital voltmeter, a 5 dollar unit from Amazon. When I first push my momentary switch to turn it on the meter flashes 6.78 then shows the volts. Whats the 6.78?

One possibility, the digital meters go through multiple steps to home in on the exact voltage. It could just be passing through the reading you see on the first display cycle. I have some AC voltmeters that read too low on the first couple of display cycles. I just ignore the reading until it stabilizes.
