Operation
Creating a New File
Set the operating screen to the desired parameters. This includes temperature or voltage, unit of
measure, thermocouple type, reference-junction temperature, offset, and lead material. Next
press MENU and select MEMORY. When there are no files stored, the only option is to store the
current screen setup as a new file using the SAVE AS function and then selecting <NEW> per
force.
At this point, enter a name for the current setting. File names can be up to 16 characters long
using letters and numbers. Use the right ARROW KEY or press the ENCODER to append characters
to the file name. The file name can be created using the KEYPAD, the ARROW KEYS, the
ENCODER, or any combination thereof. Additionally, the +/− key acts as a delete key to erase the
character above the cursor (for example, if a file is named BRAIN, placing the cursor under the I
and pressing +/− will change the name to BRAN). When ENTER is pressed, the current setting
becomes the WORKING FILE as indicated on the screen.
To enter more files, press MENU (or ESC twice) to return to the operating screen, make the
desired changes (make sure to press ENTER so that the Model 1140A knows that the screen has
been permanently updated as indicated by the lack of the blinking cursor) and again press MENU,
then MEMORY. To overwrite the existing working file, use SAVE (note that the SAVE option is not
available unless the operating-screen settings differ from the working file). Otherwise select
SAVE AS, then <NEW>, and then enter the new name for the file. When the file name is correct,
press ENTER. At that time, the newly created file becomes the WORKING FILE.
Opening a File
To open a file, press MENU, select MEMORY, OPEN, and then select the file to open. The file
selected becomes the working file, and the operating screen is changed to the newly selected
screen’s settings.
Saving a File
Saving a file uses the current operating screen settings and overwrites the working file. Press
MENU, select MEMORY, and then SAVE. At this point, the working file has been changed, and the
SAVE option on the menu is no longer present.
Saving a File As
To save a file under another name, press MENU, select MEMORY, and then SAVE AS. Then select
either <NEW> or an existing file name to overwrite. If <NEW> is selected, key in the new file’s
name as described above. If an existing file is chosen to be overwritten, the user will be
prompted to confirm the action.
Renaming a File
To rename a file, press MENU, select MEMORY, and then RENAME. Next select the file name to be
changed, change it, and press ENTER. If it is decided not to change the name, press ESC. Either
way the file, new name or old, becomes the working file. Return to the operation screen by
pressing ESC twice or MENU.
