Does the meter have a calibration screw on it? If it does adjust
it so it matches the reading of the digital at the batteries.

Thanks for this tip. I didn't know that there is such a thing in a
voltmeter. I will find out when I get back home.

I could not find anything looks like something for calibration in the
voltmeter. Thanks for the tip though.

Jay,
I do not know about the meter you have. But most analog meters
including analog multimeters have a screw at the pivot point of the
needle.

Look at the enlarged picture of the meter.

That looks like much more sophisticated than the simple analog
voltmeter on the dashboard of my boat. Mine is just a round thing with
a needle and a couple screws at the back with backlight. OK, I will go
looking for some thing similar to the voltmeter in my boat and see if I
can find an instruction manual and a wiring diagram for it.

Thanks for taking the time to find a sample marine voltmeter for me to
take a look.
