The 7600 Plus LCR Meter performs precision impedance measurements over a frequency range of 10 Hz to 2 MHz. The LCR Meter can measure 14 different impedance parameters with 0.05% accuracy, meeting today’s requirements for component and material testing. The ease of use and user-friendly menu programming makes the 7600 Plus ideal for applications in product development, incoming inspections, or production line testing.

Swept Measurements: Fast and accurate swept parameter measurements, graphical or tabular, for verification of component and material response to changes in ac test frequency, ac test voltage or ac test current, without the need for complex programming or an external controller
7600 Plus Sweep Display

Program and Data Storage: Test setups can be stored and recalled from internal memory or USB memory stick. Measured data can be stored on a memory stick and then transferred to PC for data reduction and analysis. 
Load Correction: Substantially improves instrument accuracy by performing measurements on a known standard and applying the correction to subsequent measurements. Ideal for repetitive testing of identical devices at like test conditions.
Automatic Calibration Procedure: The 7600 can be calibrated without returning the unit to the factory using a traceable IET/QuadTech 7000-09 Calibration Kit, reducing down time and calibration costs.
Easy to Use: Large LCD graphics display and user friendly menu driven interface allows the 7600 to be put on line quickly, providing useful measurements by operators with little to no training.
