Digital Multi Meter comparison measurements of a car battery voltage.

In this video I have two popular Fluke digital multi meters and a AstroAI DM6000. The voltage source is a regular common 12 volt car battery. All I'm doing is seeing what are the differences in the readings between the three. Not bad considering the Astro digital multi meter cost 10% of a fluke with a whopping price tag of $30 not on sale.
