11. Record Gain Accuracy:
a. Calculate V
diff
as follows:
V

in the worksheet. (See Table 14.)
c. Calculate Gain Accuracy as follows:
Gain Accuracy =((V

) * 100%
d. Enter Gain Accuracy in the worksheet and in the test record.
12. Repeat steps 9 through 11 for each vertical scale setting in the test record.
