LASCAR SP300-BLUE User Manual
SP 300-BLUE 3½ Digit LED Voltmeter Module
PRODUCT DESCRIPTION
The SP 300-BLUE features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are
user selectable. The SP 300-BLUE features a negative rail generator which enables the meter to measure a signal
referenced to its own power supply 0V. The blue 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.
