7.4. Setting up the limit outputs (02. & 03. menu items)
Function The instrument has two limit outputs. They are identical
with each other, and work independently.
Operation: the instrument keeps comparing the displayed
physical value with the (adjustable) limit value. It switches
the output ON depending whether the displayed value is
higher than the limit value. (There are other operating
modes too, in which it operates if the displayed value is
between or out of the two (adjustable) limit values.)
In Chapter
10.8. Limit outputs in the Appendix you find a
detailed training material on the limit outputs.
Setting the operating
mode
Sequence of operations
1. Enter the menu with the supervisor code.
The way the code should be type in can be found in
Chapter
7.1. Typing the code in . You see on the display:

.
2. Keep stepping by pressing the ▲ button as long as you
see this menu item:
