General procedure for adjusting settings
By following the flow diagram, you can move to any menu item you wish using the three
buttons (Up, Down and Mode).
For example: output 2
-Comparator mode
-lower threshold -0.3 bar
-upper threshold -0.5 bar
-Position of normally closed contact
-Closing delay 0 sec.
-Release delay 0 sec.
Procedure: Measure mode output
a)
Briefly press Mode button
b)
Briefly press Up button
c)
Briefly press Mode button to enter Menu level.
d)
Proceed to desired menu item with Up or Down button and confirm by pressing
Mode button.
e)
In this case: confirm HY2 with Mode button.
f)
Go to the desired setting with the Up or Down button
In this case: CP2. Then confirm setting with Mode button.
g)
To adjust further settings, follow the procedure in d) above.
In this case, set U-2 (lower threshold) and confirm with Mode button.
=> U-2 display flashes
h)
Adjust the desired setting with the Up or Down button.
In this case: set U-2 to 0.50 and then confirm setting with Mode button.
i)
Proceed in the same way for all other settings.
j)
To enter another setting level, e.g. output 1 (OU1) or special functions (SF),
you use the Up or Down button to go to the menu item rEt (Return). If this is
confirmed with the Mode button, you arrive at the previous level. In this case
you would arrive at the menu item OU2 and now you can switch between the
menu items Output 1 or Special functions with the Up or Down button in order to
adjust settings.

changes or manipulation. To activate the locking function, proceed as follows:
Starting state is Measure
Briefly press Mode button (select level)
Press Up or Down button until SF reached
Briefly press Mode button until menu entered
Press Up or Down button until UnL reached
Briefly press Mode button until menu entered
Set BLC with Up or Down button
Confirm setting with Mode button
5.) Deactivate key lock
Briefly press Up, Down and Mode buttons simultaneously
Briefly press Mode button once
Set UnL with Up or Down button
Confirm with Mode button
Return to Measure state via rEt (Return) menu item
