The QuadTech 7600 is a high-precision LCR meter belonging to the legacy QuadTech 7000 Series. Designed for rigorous component and materials testing, it covers a wide frequency range from 10 Hz to 2 MHz with 289,900 programmable frequencies. The instrument delivers a basic measurement accuracy of 0.05% and can display any two of its 14 measured impedance parameters simultaneously. With standard RS-232, IEEE-488 (GPIB), parallel printer, and PLC handler interfaces, the QuadTech 7600 is highly versatile for automated test environments, QA inspections, and laboratory calibration.
