Re: Battery issue
The electronics inside are reading a voltage and depending on how well it's made it could very well fluctuate. The electronics might be setup to read 12.6999999999 but displays 12.6 but then if it goes up from this point ever so slightly, then the display instead of reading 12.6 would now read 12.7.
Some meters out there have a peak hold to where this comes in handy to where if an electrical circuit normally reads 12.6 or so but then something happens for a split second the meter grabs that high number and displays that. I had a customer years ago that I installed a radio and all was well but after he drove away the audio quit working. He brought it back and it started working again. Long story short, I ended up hooking up my Fluke meter and after a few times of revving the motor up the voltage finally peaked for just a split second at 19 volts or so and then the radio's protection sensed this and turned off the audio output. The display although worked and stayed on the whole time.
Little fluctuations like a 0.1 volt or so on a 12 volt system is nothing to worry about. It's going to happen.
