Lamp Change
Allows the user to select between deuterium,
automated (instrument uses either the
deuterium or tungsten lamp to run the
selected wavelength) and tungsten lamps.
Bandwidth
Sets spectral bandwidth.
Integration
Allows the user to determine the integration
(measurement) time.
Timers
Enables up to four countdown timers to be
incorporated into the method sequence. A
timer title allows the user to specify the action
(e.g., shake, boil) associated with the timer. At
the end of the timer period, the program may
