4. Verify Trigger Output is Enabled In NetDAQ Logger, select Setup |
Instrument Config. In the Instrument Configuration dialog box, verify the
Trigger Out box is checked. Click OK to return to the Main Window. (See
“The Instrument Configuration Dialog Box" in Chapter 3 of this manual.)
5. Connect Trigger Output Connect the TO test lead on the
ALARM/TRIGGER IO connector to the Σ (Totalizer) test lead on the
DIGITAL I/O connector. This allows each Trigger Output pulse to be counted
by the Totalizer.
6. Start Instrument Scanning Click the Start Instrument button on the Button
Bar to enable instrument scanning.
7. Open Spy Window Select the Spy command from the Utilities menu. Select
01TOTAL. Click OK to open the Spy window.
8. Verify Totalizer Count The Spy window displays the Totalizer count. Note
the Totalizer is incrementing at 1-second intervals as it counts the Trigger
Output pulse at the start of each scan.
9. Close Spy Window.
10. Stop Scanning Click the Stop Instrument button on the Button Bar to stop
instrument scanning.
Calibration 6-33.
Note
Refer to the Service Manual (PN 942615) for calibration
procedures. The instrument must be stabilized in an environment
with an ambient temperature of 22
°
C to 24
°
C and a relative
humidity of less than 70%, and must have been powered at least 30
minutes prior to calibration.
The instrument features closed-case calibration, that is, calibration that is
completed over the RS-232 interface. Using known reference sources, closed-case
calibration has many advantages. There are no parts to disassemble, no
mechanical adjustments to make, and the instrument can be calibrated by an
automated instrumentation system.
The instrument should normally be calibrated on a regular cycle, typically every
90 days to 1 year. The chosen calibration cycle depends on the accuracy
specification you wish to maintain. The instrument should also be calibrated if it
fails the performance test or has undergone repair.
