DPM 2
8.25mm (0.32鈥? Digit Height
Programmable Decimal Points
Auto-zero
Auto-polarity
200mV d.c. Full Scale Reading (F.S.R.)
3錕?frac12; Digit Subminiature LCD Module
The DPM 2 uses the latest miniaturisation techniques to produce a very compact meter. The snap-in integral bezel makes installation easy. For
single rail use, the DPM 2S features a built in negative rail generator, enabling the meter to measure a signal referenced to its own power supply
0V
.
SCALING
A potential divider may be used to alter the full scale
reading (F.S.R.) of the meter - see table.
NOTES
The meter will have to be
re-calibrated by adjusting
the calibration potentiometer
at the rear of the module.
