Initial Test Connection
Note
Initial test connection is same as AI Offset, as shown in Figure 1 or
Figure 2.
Verification Procedure
Complete the following procedure to verify the AI gain accuracy.
Repeat 2 times, once for each channel.
1. Connect the AI channel under test to the Calibrator as shown in
Figure 1 or Figure 2.
Repeat 6 times, once for each gain setting.
2. Configure the calibrator to generate an output with the amplitude
and frequency from Table 4.
3. Create and configure an AI Voltage channel task using the values in
Table 5 .
