DIAG – Displays the choice list
of diagnostic tests.
CONFIGURE – Displays the
first Configuration screen.
TRACE – Displays the
absorbance monitor trace for
channel A or B.
Scale – When the wavelength
trace or spectrum screen is
visible, this function permits
modification of the display
range in the
x
(time or
wavelength) and
y
(absorbance) dimensions.
Shift – Enables the shifted functions (identified by the text at
the top of most keys). The shifted state is temporary and
resets after the next keystroke.
0-9 – Enters a numeral, from
0 through 9, into a current
field. Also positions the cursor
at the corresponding entry in
a list (0 = tenth item). Selects
the corresponding number
from a choice list.
0-9 – See descriptions for
specific shifted numeric keys.
1 – See 0-9, above.
Lamp – Displays a lamp use
statistics for the currently
installed lamp and provides
the means for you to turn the
lamp on or off. The current
state of the lamp is indicated
by an icon on the absorbance
screen.
2 – See 0-9, above.
Lock – Use from the
absorbance screen, to lock or
unlock the keypad. The lock
prevents inadvertent changes
to detector settings. The
current lock state is indicated
by an icon on the absorbance
screen.
3 – See 0-9, above.
Calibrate – Initiates
wavelength calibration.
4 – See 0-9, above.
System Info – Displays system
information including firmware
version and instrument serial
number.
