The pin assignments of the relays in the de-energized state are described in section Pin
assignments (Page 54).
The functions which can be assigned to the relays have the following meanings:
Limit messages
The upper and lower limits can be defined as events for tri
g-
ge
ring relays. Select the desired relay(s) in the second and
third lines of this menu.
This function is specific to the component.
Relays for MR
A relay for range switchover can be assigned to each comp
o-
nent. This guarantees reliable a
ssignment of the analog output
signal to the currently active range, especially with autoranging
(see section Parameter: Measuring ranges (Page 125)).
