DPM 40
A compact low-cost LED module ideally suited for applications where a bright display under all conditions is required. The DPM 40 is fitted
with high efficiency LEDs and supplied with a filter and bezel to give a high contrast display. The small size and low cost of the unit makes it
SCALING
Two resistors Ra and Rb may be fitted in order to alter
the full scale reading (F.S.R.) of the meter - see table.
The meter will need re-calibration .
