1. Select Celsius or Fahrenheit to use as temperature units for thermocouple and
RTD temperature measurements.
2. Select a monitor channel. This channel will automatically be displayed on the
instrument’s front panel when logging is started.
3. Check Totalizer Debounce to prevent false counts that can occur when the
Totalizer input is from contact closures.
4. Select the desired trigger types and enter intervals in seconds (00000.000 to
86400.000).
The NetDAQ instrument performs a scan when it detects a trigger event. The
source of the trigger event depends on the combination of trigger types
configured in the instrument. The characteristics for each trigger type and
trigger type combination are as follows.
• Interval Only
A scan is triggered immediately after logging starts. Each successive scan
is triggered after Interval 1 elapses since the start of the previous scan.
