Voltmeter Behavior, Verify Accuracy Options

Here’s the background:

I have two gauges, tested both at a variety of voltages

Both do have some “sticktion” in the needle due to damping that results in a minor delay between the time voltage hits the gauge and when the needle moves.

This is more pronounced the lower the voltage. At 8v it is very noticeable. At 11v it is hardly noticeable. At anything 12v or above, I’d say the needle movement is almost instantaneous with initial needle over shoot and then the needle quickly damps out to the indicated voltage.

Both gauges read a bit on the high side vs actual voltage. Approx .5v high. This diminishes as the voltage approaches full scale.

Pictures to follow
