4.3.1.1 Entering Numerical Values
A common method of entering values is used within menus
requiring numerical entries. Once a menu is selected, the user
starts an entry by pressing a digit or the decimal key. The display
will begin a new entry and display a cursor
as a prompt for the
next digit or decimal entry. To accept the entered value, press the
key. Values are not applied to the operation of the
instrument until the
key is pressed and the cursor prompt
disappears from the display. An example of an entry in progress is
illustrated below:
If the
key is pressed once while entry is initiated, the entered
digits will be cleared and the cursor will remain for reentry of a new
desired value. If the
key is depressed twice, the setting will
revert to the previous value and the entry is cancelled.
4.3.1.2 Menu Option Selection
Some menus may require the user to cycle through and select from
a list of predefined options. Such menus will display the cursor
which indicates that a list of predefined options are available from
which to select. Pressing the
key moves the cursor forward
within the list. The value to which the cursor points is the specified
setting and is effective immediately upon selection.
4.3.1.3 Exiting Menus
Menus are exited by pressing the
key while no numerical
entry is in progress. The display will revert to the default display
(see paragraph 4.3 above).
4.3.2 HI Menu
Accessible by pressing the
key. The “HI” menu adjusts the HI
alarm level in the selected units. When the measured liquid level
exceeds the HI alarm, the HI/LO LED on the front panel is
energized amber (Channels 1 and 2 only) and a set of alarm
contacts are closed on the 9-pin D-sub J5A and J5B connectors on
the rear panel (see the Appendix for the pinout). The audible alarm
