DPM 2000 3½ Digit LCD Module
The DPM 2000 uses advanced components and construction techniques to provide an unrivalled combination of high performance,
elegant appearance and low cost. The module uses a bandgap reference for extra temperature stability. For single rail operation, the
DPM 2000S features a built-in negative rail generator, enabling the meter to measure a signal referenced to its own power supply 0V.

Ra
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.
Ensure that link 10 is open if fitting Ra.
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).
