NI 9263 Calibration Procedure
Verification
The following performance verification procedure describes the sequence of operation and
provides test points required to verify the NI 9263. The verification procedure assumes that
adequate traceable uncertainties are available for the calibration references.
Accuracy Verification
Complete the following procedure to determine the As-Found status of the NI 9263.
1.
Set the DMM to Standby mode (STBY).
2.
Connect the DMM to the NI 9263 as shown in Figure 1.
Figure 1.
Accuracy Verification Connections
3.
Set the DMM to read DC voltage in the minimum range required to cover the NI 9263
output range of ±10 V.
4.
Acquire a sample
a.
Create and configure an AO voltage channel according to Table 2.
b.
Start the task.
c.
Generate a voltage output according to Table 3.
d.
Wait the appropriate time for the DMM measurement to settle.
e.
Read the NI 9263 output voltage measurement from the DMM.
f.
Clear the task.
