SP 400

ELECTRICAL SPECIFICATIONS

PRODUCT DESCRIPTION

The SP 400 features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are user selectable.

400 features a negative rail generator which enables the meter to measure a signal referenced to its own power supply GND.

backlighting ensures excellent readability under low light conditions. The module is easily fitted into the panel, using the fixing clip

provided. The module's

splash proofing using the supplied seal.

FEATURES

TYPICAL APPLICATIONS

• Precision Instrumentation Systems

• Power Supply Monitoring

• Test Boxes

• Panel-Mount Indication

• Low Power Voltage Measurement

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).

•

• 200mV d.c. Full Scale Reading

• 3.0 to 7.5V or 6.0 to 15.0V Operation

•

• Low Battery Warning

• Splash Proof
