QuadTech Inc, Precision LCR Meter (7400)

Description

Automatic Test Sequencing: Run up to six different tests in sequence with a single push of the start button. Each test can have different test conditions and limits.

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.

Program and Data Storage: Test setups can be stored and recalled either from internal memory or from standard DOS formatted 3 1/2" floppy disks. The front panel controls can be locked out, with password protection, to insure procedures are run the same way every time. Measured data can be stored on a floppy disk 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 7000 can be calibrated without returning the unit to the factory using the NIST traceable QuadTech Calibration Kit, reducing down time and calibration costs.

Easy to Use: Large LCD graphics display and user friendly menu driven interface allows the 7000 to be put on line quickly, providing useful measurements by operators with little to no training. The 3 ½” disk drive allows for transfer of test results to PC for data analysis.
