The firm I work for performs a variety of testing services. This picture is a DC volt meter full scale reading -3.0 to +3.0. Typical battery readings are 2.15-2.35 (float to equalize). The user has to be fast and familiar with the scale to read the numbers beyond the decimal point.

Now a days with digital meters apprentices often give us readings into the 1000s of a volt, which is really not necessary. We have to tell them just because you can obtain some data it is not always necessary.
