input mode.

PRODUCT DESCRIPTION

The DPM 3AS-BL features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are user

selectable.

of the panel meter's housing allows the module to be

suit high and low volume applications. The DPM 3AS-BL is intended to replace the DPM 3, DPM 3S, DPM 3-BL and

DPM 3S-BL in many applications, usually requiring only minor circuit modifications.

FEATURES

TYPICAL APPLICATIONS

• Precision Instrumentation Systems

• Power Supply Monitoring

• Hand held instruments

• Panel-Mount Indication

• Low Power Voltage Measurement

ELECTRICAL SPECIFICATIONS

SAFETY

To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pins must not exceed

60Vdc. The user must ensure that the incorporation of the panel meter 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).
