SP 300

Specifications liable to change without prior warning

PRODUCT DESCRIPTION

The SP 300 features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are user

selectable. The SP 300 features a negative rail generator which enables the meter to measure a signal referenced to its

own power supply 0V. The bright red LED display ensures excellent readability under low light conditions. The module

is easily fitted into the panel, using the fixing clip provided. The module's low cost means it will suit high and low volume

applications. The design of the panel meter's housing and seal ensures splash proofing in many applications.

FEATURES

TYPICAL APPLICATIONS

• Precision Instrumentation Systems

• Power Supply Monitoring

• Test Boxes

• Panel-Mount Indication

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).
