DPM 500-BL
3½ Digit Backlit LCD Module
The DPM 500-BL uses advanced components and construction techniques to provide a uniquely compact unit. The meter is in a 40 pin DIL
integrated circuit format that can be plugged directly into a DIL socket or panel mounted using the snap in bezel.

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.
Meter will need re-calibration.

SAFETY
METHOD
40 Pin DIL IC Socket
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).

PANEL FITTING
Fit the bezel to the front of the
panel and locate the meter into
the bezel from behind.
Alternatively the meter and
bezel may be assembled before
fitting to the front of the panel
but care must be taken not to
use excessive force. Finally fit
the window into the front of
the bezel.
