desired wavelength.
Displays the current active slit. The slit width and height provides the
optimum sensitivity, the best signal-to-noise ratio and good linearity of the
calibration curve at the recommended wavelength.
Touch-entry field that displays the spectral width and height of the slit
selected to measure the absorption.
To change the slit, touch this field to display the Slit dialog and select the
required slit.
You touch this button to set the bar graph to mid-scale and perform AGC/
AIC when you are setting up a lamp. The system does this automatically
for a lamp when you select Setup Instrument.
When you have set the lamp parameters, touch this button to set up the
system with the lamp parameters. The system switches the lamp on, sets up
the optical path (prism and grating), sets and peaks the wavelength, sets the
slit, and performs an Automatic Gain Control (AGC) and Automatic
Intensity Control (AIC).
You touch this button to display the Install Lamps dialog (see below).
