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.
SHIFT PORT
To change the port, press this key. Followed by either 1 or 2 and then press
ENTER. The number 1 corresponds to the axial port and the number 2
corresponds to the lateral output port.
FILTER
Move the Filter Wheel accessory to the specified position. Press FILTER, then
type the number 1, 2, 3, 4, 5, or 6 indicating the desired position, then finally press
ENTER to execute the move.
SHIFT LABEL
This key (located directly above FILTER) provides access to the filter label. These
labels are eight-character alpha-numeric fields, used for information only. 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.
LOCAL
Use this key to toggle between “local” communication through the Hand Controller
and “remote” communication with a computer. Please note that if you press
LOCAL to activate the Hand Controller (the display is lit and information fills the
screen), you also lock out PC communications. You cannot command the MS260i
via either RS-232, IEEE-488 or USB while the Hand Controller is active.
SHIFT UNITS
To change the wavelength units press this key, followed by either 1, 2, or 3 and
then press ENTER. Those three number keys are labeled with the corresponding
units: 1 is nanometers (nm), 2 is micrometers (µm), and 3 is wave numbers (cm

Press this key to enable the top half command of any applicable key.
SHIFT DEL
Press this key to delete an entry.
ENTER
Press this key to complete a command, where applicable and denoted above.
