To Set Start Phase
The setting range of start phase is from 0° to 360° and the default is 0°.
The start phase displayed on the screen is the default value or the phase previously
set. When the instrument function is changed, the new function will still use this
phase.
Press Start Phase to highlight the softkey. At this point, use the numeric keyboard
to input the desired start phase value and then select the unit “°” from the pop-up
menu.
Users can also use the direction keys and knob to set the parameter value: use the
direction keys to move the cursor to select the digit to be edited and then rotate the
knob to change the number.
