Waveform Judgments
Waveform judgment area and judgment threshold value automatic
settings functions
Waveform judgment areas and judgment threshold values are set automatically by the instrument
based on the waveform and variability at the set voltage during voltage calibration so as to optimize
judgment settings for waveform judgment functions.
This function can be set individually using the next judgment function. The judgment threshold
values and judgment areas for the enabled judgment functions are set automatically during voltage
calibration.
• Surface area comparison judgments [AREA]
• Differential surface area comparison judgments [DIFF AREA]
• Flutter detection judgments [FLUTTER]
• Secondary differential detection judgments [LAPLACIAN]
Each judgment function sets threshold values by adding the result of multiplying the average
measured value by the margin rate to the variability exhibited by each measured value during
voltage calibration.
