Initiating a DC-bias scan
You can initiate a new DC-bias scan after the initial power-up of the unit and when you require a new
scan of the current Min-Min-Quad bias points.
To initiate the scan:
1.
Click FORCE CALIBRATE in the CONTROL tab or in the HISTORY tab.
2.
During the re-calibration process, the color strip under the bias label will turn orange. Once the
unit has found the correct bias point, the color strip will turn green.
