7.2 Hands on setup
In this philosophy of operation, you set a threshold to give you a “heads-up” minor alarm so you
can “track” the incoming storm and then decide what action you wish to take (yourself, manually)
when a certain closer threshold is reached.
To achieve this dual-threshold capability, it is necessary to use the Metering Math Functions
built-in to the Davicom units. The MMF’s have two-level alarm capability built-in. The example
below shows that a Minor Alarm has been set for a minimum distance of 30 km and a Major
Alarm has been set for a minimum of 10 km. Note the * in the “High” field, indicating a “don’t
care” condition.
