Model 215 is an economical, 5-volt powered, 3 1/2 digit DC voltmeter in a compact 1/16 DIN case. The height of the panel cutout is only 0.88 in (22.2 mm), and the depth behind the panel is only 2.83 in (72 mm). Power consumption is 1 watt at 5 V dc. Low cost, small size and low power consumption at 5 V dc make the 215 ideal for OEM and portable-instrument applications.

Model 215 used in ratiometric mode. Load exciation and the +1 V dc reference are provided by the same +5 V dc that powers the meter.
