17.3 KEY REFERENCE
These commands are listed based on the key locations from the top of the controller to the bottom,
left to right.
ABORT- If you accidentally press a function key or enter a bad parameter you may press
the ABORT key to clear that command before it executes. The ABORT key has
no effect on most functions once the command is executed (by pressing
ENTER). However, wavelength motion will stop immediately upon ABORT and
the display will update to show the wavelength where motion was halted.
STEP DOWN Press this key once to move the Cornerstone to shorter wavelengths by the
smallest possible increment. Holding this key causes rapid single stepping
toward lower wavelengths. Press SHIFT and then STEP DOWN, you can use
the keypad to define a number of steps to move at once. Press ENTER to
execute this larger move.
STEP UP Press this key once to move the Cornerstone to higher wavelengths by the
smallest possible increment. Holding this key causes rapid single stepping
toward higher wavelengths. Press SHIFT and then STEP UP, you can use the
keypad to define a number of steps to move at once. Press ENTER to execute
this larger move.
GO WAVE This key induces wavelength motion to a specified position. Press GO WAVE,
then use the keypad to enter the desired wavelength, and finally press ENTER
to execute the move.
GRAT Press this key to move to the other grating position. Press GRAT, then press
either 1 or 2 on the numeric keypad, and finally press ENTER to execute the
change. The display will update to show the correct parameters for the new
grating.
SHIFT LABEL This key (located directly above GRAT) provides access to the grating label.
The label is an eight character alpha-numeric field that is used for information
only. Newport puts the grating blaze wavelength as the label during calibration.
However, you can use the keypad to type any number, then press ENTER to
accept that new value. The Hand Controller display only shows the first four
digits of the label, and you can only enter numbers.
LINES Press this key to change the lines/mm of the grating. This value is used for
wavelength calculations and will affect your calibration. This parameter should
be changed only when adding a new grating.
SHIFT CALIB- This button is used to change the wavelength calibration of the current grating.
Use the GO WAVE, STEP DOWN, and STEP UP keys to move to a known
wavelength (often the intensity peak for a spectral calibration lamp). If the
wavelength shown in the top row of the display does not match the known
value, press SHIFT CALIB and use the numeric keypad to enter the known
wavelength. Then press ENTER to change the calibration. The current grating is
thus calibrated over its entire range.
SHUTTER Alternately, open and close the shutter by pressing this button. The shutter
position is shown in the display as “OPN” for open and “CLS” for closed.
