Trigger
Action
Operator
Selects whether the trend data collection will Start or Stop when the
trigger comparisons are true. If set to Start, data collection will stop
after one screen of data is collected.
Trigger Delay Operator
Allows the data collection start or stop to be delayed after the
triggers evaluate as true. The delay is selectable from 1 to 864000
seconds (10 days). Display is in days, hours, minutes and seconds.
The delay timer begins when the triggers evaluate as true. If the
Trigger Action is set to Start, data collection will begin after the
triggers evaluate as true and the delay timer has elapsed. If the
Trigger Action is set to Stop, data collection will stop after the
triggers evaluate as true and the delay timer has elapsed.
Primary to
Secondary
Operator
Operator
Selects whether the Primary Trigger, Secondary Trigger or both
have to be true in order to start or stop data collection. Selections
are AND, OR, XOR and None. If NONE is selected, the Secondary

•
If AND selected: Both Primary AND Secondary are true
•
If OR selected: Either Primary OR Secondary (or both) are true
•
If XOR selected: Either Primary OR Secondary (but not both)
