SP 400 Digit Backlit LCD Voltmeter Module PRODUCT DESCRIPTION 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. • 9.75mm Digit Height • 200mV d.c.
