Lascar SP 300-BLUE 3% Digit LED Voltmeter Module User Manual
The SP 300‑BLUE module provides a 200 mV DC full‑scale reading with auto‑zero and auto‑polarity, a blue LED display for low‑light readability, and a negative rail generator that allows measurement referenced to its own power supply. It is panel‑mountable using a fixing clip and is designed for both high‑ and low‑volume applications with splash‑proof housing.
The manual includes electrical specifications, safety guidelines complying with the Low Voltage Directive, dimensions, pin configurations, circuit diagram, scaling options, and application notes for voltage, current, and 4‑20 mA loop measurements.
