f. Measure second mean:
Set the generator to the second level and polarity indicated in the table
for the vertical scale, position, and offset settings you have made.
Repeat substep e using the current vertical scale, position, offset, and
new generator setting for the second mean.
g. Check against limits:
Subtract the second measurement mean from the first measurement
mean for the current vertical scale, position, and offset.
Record the difference of the two mean measurements in the Difference
of Measurement Means column of the table. (See Table 3-5.)
CHECK that the Difference of Measurement Mean is within the limits
listed for the current vertical scale/position/offset/generator settings.
Enter measurement mean difference value on test record.
h. Repeat substeps d through g, using the next position, offset and generator
settings listed in the table for the current vertical scale.
i. Repeat substeps c through h until all vertical scale settings, listed in the
table, are checked for the channel under test. (See Table 3-5.)
j. Test all channels: Repeat substeps a through i for all four channels.
3. Disconnect the hookup:
a. Set the generator output to 0 V.
b. Disconnect the generator output from the channel last tested.
