Active Channels
Use the Measurement section of the Measurement Setup screen, Figure 25,
to set sensor channel activity parameters. All of these settings are optional
and do not affect data measurement and recording:
•
Active Sensor Channels – 1 to 4 checkboxes to enable channel
output display on the Sensor Display screen; channel output
readings on the Node Summary screen are not affected; user’s
option.
•
Enter Alarm Information – High/Low Fail/Warning and Units;
user’s option.
•
Alarms Enabled - 1 to 4 checkboxes; user’s option.
Triggering
Triggering is a user’s option, selected in the recording options of the
Measurement section of the Measurement Setup screen. If selected, an
entry for Pretrigger Fraction must be selected from its dropdown list, 0%,
50%, or 100%. Pretrigger Fraction is the percentage of the measurements
recorded just prior to the trigger event. Figure 27 illustrates the three
choices for this parameter.

After Pretrigger Fraction is set, then the Trigger Enabled checkboxes must
be appropriately checked in the Active Sensor Channel section.
Use the Channel Trigger section of the Measurement Setup screen, Figure
25, to set triggering parameters for each sensor channel. A single value or
two values can be set. The two-value setting can be either AND’ed or
OR’ed in the small dropdown list box beneath the sensor selection box.
