3.4.6 Calibration
Set calibration related items. The calibration status is displayed in the upper left corner of the screen.
The calibration status and display are as follows:
No calibration data --- (displayed in gray)
Calibrated Cor (displayed in blue)
Correction O Off (displayed in gray)
Need to re-calibrate C? (displayed in blue)
Note: The calibration status is shown as “C?” which indicates that the scan frequency range is dierent
from the time of calibration. Users need to re-calibrate in the current scan frequency range.
When performing calibration, the calibration wizard pops up. Please follow the calibration wizard to
perform calibration. After completing the calibration step, the calibration data is automatically saved as
user calibration data. Turn on the calibration switch and the error correction function will be enabled.
