6-30
Trigger Input Test 6-31.
This test checks the ability of the Trigger Input line to trigger measurement
scanning.
1. Configure Trigger Input In NetDAQ Logger, configure the scan parameters
for External Trigger with an Interval 2 of 1 second. Be sure Interval Trigger
and Alarm Trigger are not enabled. (See “Trigger Input” in Chapter 3 of this
manual.)
2. Verify Configuration Channel 1 for Volts DC In NetDAQ Logger, verify
channel 1 is configured for Volts dc, 3V range. (See "Configuring Analog
Channel Functions" in Chapter 3 of this manual.)
3. Start Instrument Scanning Click the Start Instrument button on the Button
Bar to enable instrument scanning, although no measurement scanning takes
place because the external Trigger Input is not set.
4. Open Logging Status Window Select the Show Logging Status command
from the Options menu to display the Logging Status window.
5. Verify Logging Status Note in the Logging Status window that the
Retrieved Scans count is zero and not incrementing.
6. Set Trigger Input While monitoring the Logging Status window, connect
the TI (Trigger Input) test lead to the GND test lead. Note in the Logging
Status window, the Retrieved Scans count increments at 1-second intervals.
Disconnect the TI and GND test lead connection.
7. Stop Scanning Click the Stop Instrument button on the Button Bar to stop
instrument scanning.
Trigger Output Test 6-32.
This test checks the Trigger Output (125µs logic low) that occurs each time the
instrument scans.
1. Configure Interval Trigger In NetDAQ Logger, configure the scan
parameters for Interval Trigger with an Interval 1 of 1 second. (See “The
Instrument Configuration Dialog Box” in Chapter 3 of this manual.)
2. Verify Configuration Channel 1 for Volts DC In NetDAQ Logger, verify
channel 1 is configured for Volts dc, 3V range. (See "Configuring Analog
Channel Functions" in Chapter 3 of this manual.)
3. Measure Unset Trigger Output Line Using a digital multimeter, measure
the output of the unset TO test lead, referenced to the GND test lead, for a
voltage greater than +3.8V dc.
