Triggering
This feature applies to loop measurements only.
Trigger OFF
The ExLRT will not report or display any trigger condition.
Trigger ON
Triggering can be enabled with averaging on or off. The following icons will appear accordingly
Averaging OFF, with triggering
Averaging ON, with triggering
Method of triggering
The ExLRT can trigger in two different ways
Trigger on Percentage Value
Trigger on Resistance Limits
Both methods can be enabled at the same time or either method can be applied individually. The use
of triggering is to primarily fault-find suspect loops. The ExLRT triggering feature can be used to set
limits based around a given loop value. For fault-finding, any large deviation in loop resistance due to
poor construction can be identified using the trip mechanism.
Trigger on Percentage
This trigger method can be set to a percentage from 1% to 100% and is defined as the percentage of
loop based on the first value when continuous mode starts. For instance, take three loops and their
corresponding trigger limits based on percentage of value.
