AUTO OFFSET2
This control adjusts the X2 offset and Y2 offset values so that the X2 channel and
Y2 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 or Output Offset Ref 1 Menu keys returns control to the
Output Offset Ref 1 Menu.
5.5.09 Dual Reference Auto Functions Menus
In dual reference mode, pressing a key adjacent to the Auto Functions item on Main
Menu 1 accesses the Auto Functions menu, shown in figure 5-54.
Figure 5-54, Auto Functions Menu - Dual Reference Mode
This menu is virtually identical to the normal single reference mode Auto Functions
menu, except that the an additional key appears in the lower left-hand corner, marked
Ref 2 Menu or Ref 1 Menu. Each press of this key toggles the displayed set of auto
function controls between those applying to reference 1 and those applying to
reference 2.
Note that once these functions complete, the Auto Functions menu is replaced by the
Main Display. There are four auto functions for each of the two reference channels,
which operate exactly as described for single reference mode in section 5.3.14.
Pressing a key adjacent to the Auto-Default item carries out an Auto-Default
operation and resets the instrument to single reference mode.
