14. Calculate the error in the vertical gain as a percentage of input using the following formula:
where
a = the Measured Positive Voltage
b = the Measured Negative Voltage
c = the applied Positive Voltage
d = the applied Negative Voltage
Compare the resulting percent error to the Calibration Test Limits or the Published
Specifications listed in Table 7 (NI 5122/5142) or Table 8 (NI 5124). If the result is within
the selected test limit, the device has passed this portion of the verification.
15. Repeat steps 2 through 14 for each iteration in Table 3.
