Verification

After the 15-minute warm-up time, always self-calibrate the NI 5114 before
Note
beginning a verification procedure.
This section describes the program you must write to verify either the calibration test limits or
the published specifications for the NI 5114.
If any of these tests fail after you perform an external adjustment, make sure
Note
that you have met the requirements listed in the
Procedures

Vertical Offset and Vertical Gain Accuracy

Table 4 contains the input parameters for verifying both vertical offset accuracy and vertical gain
accuracy of the NI 5114.
To verify vertical offset accuracy, complete the procedures described in the
Accuracy section for each of the 20 iterations listed in Table 4 for channel 0, then repeat the
procedures for channel 1. The Calibration Test Limits and Published Specifications for vertical
offset accuracy are shown in Table 5.
To verify vertical gain accuracy, complete the procedures described in the
Accuracy section for each of the 20 iterations listed in Table 7 for channel 0; then repeat the
procedures for channel 1. The Calibration Test Limits and Published Specifications for vertical
gain accuracy are shown in Table 6.
