Test & Measurement


Panel mounting digital voltmeter

11 July 2007 Test & Measurement

The SP 400 digital voltmeter from Lascar features a 200 mV d.c measurement range with auto-zero and auto-polarity functions, and user-selectable decimal points. It 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 has a low profile and can be fitted into either the front or rear of the panel easily, using the fixing clip provided.

The SP 400 features LED backlight current drain of 30 mA, input leakage current of only 10 pA and a low battery warning. The meter measures 22,4 x 35,1 x 18,91 mm with a panel cut-out of 34 x 21,3 mm and its housing is designed to ensure splash-proof IP65 protection using the supplied seal.
