allow manual adjustment of the X channel and Y channel output offsets. The offset
level set by the controls, which can be any value between -300% and +300% in
0.01% steps, is added to the X channel or Y channel output when the X channel or Y
channel offset is switched on. Adjustment is faster using the Keypad or Active
Cursor controls - see section 4.1.04.
The values are set automatically by the Auto-Offset function, which also switches on
both X channel and Y channel output offsets.
OFFSET STATUS
This control allows the X channel and Y channel output offsets, set by the above
level controls, to be switched on to either or both outputs, or to be switched off. It
therefore has four settings, as follows:-
NONE
Both X channel and Y channel output offsets are switched off.
X
The X channel output offset is switched on.
Y
The Y channel output offset is switched on.
X&Y
Both X channel and Y channel output offsets are switched on.
OUTPUT EXPAND
This control allows a ×10 output expansion to be applied to the X, Y or both output
channels, or to be switched off:-
NONE
Output expansion is turned off.
X
A ×10 output expansion is applied to the X channel output only.
Y
A ×10 output expansion is applied to the Y channel output only.
X&Y
A ×10 output expansion is applied to both the X channel and Y channel outputs.
AUTO OFFSET
This control adjusts the X offset and Y offset values so that the X channel and Y
channel outputs are zero. Any small residual values can normally be removed by
calling Auto-Offset for a second time after a suitable delay to allow the outputs to
settle.
Pressing the Previous Menu key returns control to Main Menu 1.
5.3.08 Output Equations Menu
When Main Menu 1 is displayed, pressing a key adjacent to the Output Equations
item opens the Output Equations Menu, shown in figure 5-11.
