SP 400
PRODUCT DESCRIPTION
3½ Digit Backlit LCD Voltmeter Module
The SP 400 features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are user selectable. The SP
400 features a negative rail generator which enables the meter to measure a signal referenced to its own power supply GND. LED
backlighting 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 ensures
splash proofing using the supplied seal.
FEATURES
• 9.75mm (0.38") Digit Height
• 200mV d.c. Full Scale Reading
• 3.0 to 7.5V or 6.0 to 15.0V Operation
• Auto-zero and Auto-polarity
• Programmable Decimal Points
• LED Backlighting
• Low Battery Warning
• Splash Proof
TYPICAL APPLICATIONS
• Precision Instrumentation Systems
• Power Supply Monitoring
• Test Boxes
• Panel-Mount Indication
• Low Power Voltage Measurement

* To ensure maximum accuracy, re-calibrate periodically.
** Operation of the meter beyond the maximum supply voltage rating may cause permanent damage to the meter.
*** An external series resistor is required above 5V, see Applications.

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).
