About Activated Triggers
A trigger is activated (displays red flag)
when a PID value meets an upper/
lower limit (trigger point).
When a trigger is activated:
•
Data collection is briefly paused as the Scanner captures a short recording of
all available PID data from just before the trigger point to just after, and saves it
as a data file.
•
A message displays indicating a data file was saved (
).
•
Data collection restarts.
Note
- T
riggers for other PIDs (not activated) will
continue to be armed
.
•
The activated PID trigger is disarmed.
Note
- if a different PID trigger is
activated subsequently, the previously recorded data file will be over written.
•
A red cursor line is displayed on the graph of the PID with the activated trigger
to indicate where the trigger occurred. A black cursor line is displayed on all the
other PID graphs to indicate their relationship to where the trigger occurred.
•
The PID name, flag icon, and current value all change color to red on the PID
with the activated trigger.
–
Note
-
When data collection restarts the current value may switch from red to
blue as the data runs over the limit and returns within limits
.

Trigger Arming/Disarming
Arming
- arms all triggers to record data if a trigger is activated.
Disarming
- prevents all triggers from activating.
Select the trigger arm control icon (in the data control toolbar) to arm or disarm all
triggers.
If trigger settings are modified, or are added for other PIDs, they are armed as soon
as you exit the setting screen.
Rearming Activated Triggers
Once a PID trigger has activated, you cannot use the Trigger Arm Control Icon to
rearm that trigger.
To rearm an activated trigger use one of the following methods:
•
Rearm Individual Trigger
a. Select the
Menu
icon
on the PID you want to rearm the trigger on.
b. Select
Setup
.
c. From the properties dialog box, select
Save.
This rearms the trigger using
the original trigger points. If different trigger points are needed, change the
Max/Min values and then select
Save
.
•
Rearm All Triggers and Clear Data
a. Select the
Clear
icon
.
b. From the confirmation screen select
Yes
.
