4.14 Using On-Line Help
The PM880 offers on-line help screens that contain descriptions and
instructions for various topics. You can access on-line help at any time by
pressing the [?] key. The on-line help screen that appears depends on what
the meter is doing at the time the [?] key is pushed. While:
•
taking measurements - the on-line help screen displays a table of
contents.
•
in the user program - the on-line help screen displays the help screen
relevant to the program menu.
Use the function keys at the bottom of the screen to navigate through
on-line help.
