The DP3001 is a low-cost, true-differential 4½ digit
panel meter for applications that require high resolution
and high accuracy DC measurement. It fits a standard
¹⁄₈ DIN panel cutout and requires a depth of less
than 104 mm (4.1") behind the panel. Display span is
±19,999 counts. Accuracy is 99.98%.

INPUT RANGES

The DP3001 offers DC voltage ranges of ±1.9999,
±19.999 and ±199.99 Vdc. By using an external
DC voltage reference, any of these ranges can be
configured for 3-wire ratio measurement.

OPTIONS

The meter can be electrically configured for three
input voltage ranges, four decimal-point positions,
high-impedance 3-wire ratio input. Mechanical options
include a screw-terminal barrier strip for signal and
power and a splash-proof lens cover which meets
NEMA 4 (IP65) requirements.
