NI PXI-4130 Calibration Procedure
5.
Record the NI 4130 output voltage measurements for both external voltages.
6.
Calculate the
Voltage Change Limit
using the formula in Table 13.
7.
Subtract the two voltage measurements,
V
1
-
V
2
, to calculate the
Voltage Change
. The test
passes if the
Voltage Change
falls within the calculated
Voltage Change Limit
.
