Stanford Research Systems SR715 LCR Meter

The Stanford Research Systems SR715 LCR Meter is a precision bench instrument for measuring inductance, capacitance, resistance, quality factor, and dissipation factor across component types and circuit assemblies. Built for incoming inspection, quality control, automated testing, and general laboratory measurement, the SR715 delivers 0.2% basic accuracy with a 5-digit LED display and flexible measurement modes including auto-ranging and manual selection. Its architecture supports both series and parallel equivalent circuit models, multiple triggering options, and direct integration with test automation systems via RS-232, GPIB, or handler interfaces.
