Two trigger points can be adjusted for each of the two relays L1 and L2.
When a trigger point is not required, it can be switched off. On versions
without relay, only the limit signalling LEDs on the instrument front are lit.

Trigger point not used
When using a Digital 380 channel selector in the automatic scan mode
(SC_on), the built-in relays are used for common alarm signalling, i.e. the
corresponding relay switches with at least one alarm in the measured
channels.
In this case, the mode (normally open or normally closed) is dependent of
the channel 1 setting.
