Managing Your Network Using Fluke DAQ
The dialog box entries include:
Interval Trigger
Uses the interval timer (interval 1 timer) to set the scan rate for normal
operation in a module. The interval is user settable.
External Trigger
Uses the Trigger input signal to start a scan. Every time the external trigger is
activated, another scan is taken.
Alarm Trigger
Uses a second interval timer (interval 2 timer) to start scanning when an alarm
condition is encountered by the module. There is an interval timer (interval 3
timer) used to look for alarms. The default for that timer is 0.1 s for the FAI
and 1 s for the PAI.
Drift Correction
Automatically selected when you set the reading rate to Slow (High Res.). You
can also click to clear the check box. Drift correction is used primarily to
compensate for temperature drift. Clearing the check box allows readings to be
taken more quickly.
Reading Rate
Select the slow reading rate for high precision or the fast reading rate for high
speed. Actual reading rate depends on the function you select.
Conditional Scan Storage
Allows you to specify when to store scan data. Always is the default selection.
On Alarm stores scan data as long as the alarm condition exists. On Alarm
Transition stores scan data only when the alarm first occurs. On Alarm stores
the least amount of data.
On Line CSV file creation
Moves scan data directly to a .csv compatible file instead of storing it first in a
binary format.
