9.5. Keypad Keys
9.5.1. Log/Linear Keypad</>
Keypad</> toggles the active spectrum window between logarithmic and linear vertical display.
This is duplicated by the Log toolbar button. The vertical scale can be controlled with the Zoom
In/Zoom Out toolbar buttons, Keypad<+>/<->, the <
8
> and <
9
> keys, and <F7/F8>.
9.5.2. Auto/Manual Keypad<*>
Keypad<*> switches the spectrum window between automatic and manual vertical full scale
(see the discussion in Section 5.9.4). This is duplicated by the Vertical Auto Scale button on the toolbar.
9.5.3. Center Keypad<5>
Keypad<5> forces the marker to the center of the screen by shifting the spectrum without moving the marker from its current channel. This is duplicated by the Center button on the toolbar. For more information, see Section 5.9.8.
9.5.4. Zoom In/Zoom Out Keypad<+>/<->
Keypad<+> increases the scale of both axes in the Expanded Spectrum View so the peaks appear larger, while Keypad<-> does the opposite, making the peaks look smaller. The scale value for both axes is always shown on the toolbar. These functions are duplicated by the Zoom
In/Zoom Out toolbar buttons.
9.5.5. Fine Gain Keypad<Alt + +>/<Alt + ->
These accelerators step the internal amplifier up or down by one increment of fine gain on the selected Detector, if it has a software-controlled amplifier. The new fine gain setting is shown on the Supplemental Information Line at the bottom of the screen. If the gain stabilizer is active, the display of the histogram data might not change.
The fine gain can also be set with Acquire/Adjust Controls... (Section 5.2.11) and
Keypad<Shift + Alt + +>/ <Shift + Alt + ->; and keyboard <Alt + +>/<Alt + -> and
<Shift + Alt + +>/<Shift + Alt + ->.
