LC and RC Values Area Judgments [LCRC AREA]
LC and RC values judgments
Test conditions settings mode
The PASS judgment area is created based on multiple LC and RC values imported from the master
workpiece after voltage calibration has been implemented.

Test mode
Judged by whether the LC and RC values of the workpiece being tested are inside the PASS
judgment area that has been created.

IMPORTANT
• The LC and RC values judgments function calculates the internal coefficients such as the waveform
operation area of the LC and RC values during voltage calibration. Consequently, make sure to enable the
LC and RC values judgments function before implementing voltage calibration.
• The PASS judgment area created during voltage calibration is set based on the LC and RC values
variation for the conforming workpiece during voltage calibration. If the settings include LC and RC values
variation for the workpiece under test, it is necessary to import the LC and RC master values and create a
PASS judgment area, or to adjust the judgment area manually.
• If the measured waveforms lacks the second and subsequent cycles, the LC and RC values will be
calculated using the area that includes the point at which the voltage was applied. In this case, the LC and
RC values will not correspond to the values calculated based on a conventional LCR resonance circuit,
but they can still be used to generate a judgment.
