LASCAR SP8-100 User Manual
SP 8-100 3½ Digit LED Voltmeter Module
The SP 8-100 features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are user
selectable. The SP 8-100 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.
