Figure 4.
PXIe-4309 DC Voltage Verification Setup Using TB-4309 (ST).
Note
When using the TB-4309 (ST) or TB-4309 (MT) to perform the DC voltage
verification, connect only one channel to the calibrator at a time.
2.
Verify that the calibrator output is not grounded (floating).
Note
To float the output of the Fluke 5700A, enable External Guard mode
(EX GRD).
3.
Set the calibrator voltage to 0 V.
4.
Set the calibrator to Operate mode (OPR).
5.
Verify the accuracy for each specified configuration in Table 4.
a.
Set the calibrator to the listed configuration and allow it to settle.
b.
Configure an AI voltage channel task using the values in Table 5.
c.
Start the task.
d.
Drop the first sample acquired for each channel.
e.
Average the remaining samples on a per channel basis.
f.
Stop and clear the task.
g.
Compare the averaged values to the specified test limits in Table 4.
