Getting Started

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.
