SCALING
Two resistors may be used to alter the full scale reading of the meter - see table.
Note that the meter will have to be re-calibrated by adjusting the calibration pot .
SAFETY
To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pins must not exceed 60Vdc. If
voltages to the measuring inputs do exceed 60Vdc, then fit scaling resistors externally to the module. The user must ensure that
the incorporation of the DPM into the user’s equipment conforms to the relevant sections of BS EN 61010 (Safety Requirements
for Electrical Equipment for Measuring, Control and Laboratory Use).

Connect to 0V to hold display reading. Leave open for normal operation.
Connect to Pin A, B or C to select required DP .
Positive power supply input.
The ground for the analogue section of the converter, held actively at 2.8V (nom) below +5V. This pin is
for use only when the module is used with a fully floating supply.
to any other terminations or circuitry except as specified in the relevant operating modes.
Positive measuring input.
Negative measuring input.
Negative power supply input.
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 very
suitable for high volume OEM applications.
