The Quadtech 7400 LCR Meter is designed to perform precision impedance measurements over a wide frequency range, 10 Hz to 500 kHz for the model 7400 and 10 Hz to 2 MHz for the 7600. The instrument is capable of measuring 14 different parameters with 0.05% accuracy
to meet today’s requirements for component and material testing. The ease of use and user friendly menu programming makes the 7000 Series ideal for applications in product development, incoming inspections, or production line testing.


  • 14 different impedance parameters - measure and display any two parameters simultaneously
  • Automatic test sequencing
  • Swept measurements - graphical or tabular
  • Program and data storage - test setups can be stored and recalled either from internal memory or from standard DOS formatted 3½" floppy disks
  • 10Hz to 500kHz frequency range
  • 0.05% basic measurement accuracy
  • 7 digit measurement resolution
