4.4 PROGRAMMING THE QUADTEC UV/Vis DETECTOR
4.4.1 Creating Programs
When creating programs, note the following:
•
The QuadTec can store up to 20 programs. By moving the cursor to the VIEW menu, you can check
the availability and allocation of program numbers.
•
All programs are saved permanently until overwritten.
•
Time displays are given in minutes with decimal calculation of seconds, i. e. 0.3 min = 18 s. Time
resolution during input is 1/10 min, during program runs 1/100 min.
•
Wavelengths and events can be changed as a function of time. Set up parameters such as scaling
of the analog outputs cannot be time programmed. All options for analog outputs like ratio plots can
be defined for entire programs and will be used when loading the program.
•
Use the EDIT mode for modifying or creating programs. Move the cursor to the “Edit Prog” field and
enter the desired program number with numeric keys. Any numeric values can be overwritten.
Pressing any arrow key confirms the actual value.
•
The first line of a program is the start time at 0 min. This time cannot be changed. The message
“Start time is fixed” appears on attempting to edit this line. The maximum value for time is 999 min.
•
To edit a new time line, move the cursor to the time field and press the Down arrow. If this line is
empty, in the time field will be displayed ***.*.

4.4.2 Deleting Programs
You can delete a program line if you enter 0 in the field time and press any arrow key. The message “Delete
this line? Confirm by cursor” will be displayed. You can confirm deletion if you press any arrow key. If you
press a numeric key, or wait for 60 seconds, deletion will be aborted.
Values 0, 1 and 2 can be used for programming of events. (See section 4.8, “Connecting Other Instruments
to QuadTec Detector.”)
