4.3 GENERAL PROGRAMMING AND EDITING
In general, the 12LS menu structure consists of several main menus each having a group of sub-menus beneath them.
The user selects a main heading and then steps through the sub-menus until the desired menu is reached.
Most menus will appear with a prompt denoting the parameter to be edited followed by a blinking question mark (?)
and the current value or setting of the parameter.
At this point the operator can press YES to select the menu for editing or press NO to advance to the next logical
menu.
When a menu is selected for programming the blinking question mark (?) changes to an equal sign (=). At that point
the UP and DOWN keys are used to adjust the value or choices offered. When the adjustment or selection is complete,
press ENTER to store the new data and the display changes to the next menu.
The following example illustrates the steps a user would take to program the input type on channel 5 as a type K
thermocouple. The default input type is type J.
EXAMPLE:
o TheINPUTTYPE menu is under the SETUP LOOP INPUT main menu. Press NO until the SETUP
LOOP INPUT menu appears.

o Press YES to select the menu for editing
o Use the UP and DOWN keys to change the type until the desired input type is displayed
o Press ENTER at this point to store the new input type and advance the display to the next menu
Pressing the BACK key before ENTER at any time returns to the previous main menu heading. If a main menu
heading is currently displayed, pressing the BACK key returns the display to the SINGLE LOOP display. Pressing the
BACK key from the SINGLE LOOP display or the BAR GRAPH display toggles the display between those two.
