Operator Control Key pad
In addition to the keyboard, the user is provided a group of keys to direct the functions of the
instrument and to display menus for editing user programs, setting up new isotopes and
setting up dpm quench curves (if dpm is installed).
The specific keys on the Operator Control Keypad are as follows:
ENTER Used following entries to indicate to the system that the information entered is
complete. Can be used interchangeably with the SELECT key on the Operator
Control keypad.
DELETE Used to correct an error in making an entry. Pressing DELETE clears the entry and
moves the cursor to the beginning of the field, ready for you to re-enter the
information correctly.
BACK SPACE Moves the cursor to the left, deleting one character at a time.
LINE FEED Advances the paper in the printer, one line at a time. Resets printer when paper out
message is displayed.
START Starts the count of the vials loaded in the sample changer, provided all necessary
setup steps have been accomplished.
STOP COUNT Terminates the current sample count and prints the results of the count up to
termination; the next sample is advanced and counting continues.
INTERRUPT Stops the counting in progress to allow counting a single rack of priority
samples.
HELP Presents a display of useful information. Pressing Help during editing displays
in-formation regarding a specific prompt. This key is a toggle switch; pressing it
again (or any key except RESET) clears the Help window from the display.
MAIN MENU Calls up a display of the Main Menu.
PREVIOUS MENU Returns to a display of the previous menu (i.e., the menu displayed before the
cur-rent one).
PRINT Causes the printer to produce a hard copy of the information currently displayed
on the screen. This key is not active when the system is counting.
CANCEL Terminates any editing function without storing the changes and returns you to
the Main Menu. If Cancel is pressed during Multi-Task, you are returned to the
Multi-Task Menu. Counting is not affected.
