SP 400
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
ELECTRICAL SPECIFICATIONS
Unless otherwise noted, specifications apply at T =25°C, V
input mode.
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).
