d. Display the test signal:
From the tool bar touch Vertical and then touch Position.
Use the keypad to set vertical position to the number of divisions listed
in the table for the current vertical scale setting and offset.
Touch Offset.
Use the keypad to set vertical offset to the setting listed in the table
for the current vertical scale and position settings. The baseline level
may move off screen.
Set the generator to the level and polarity indicated in the table for the
vertical scale, position, and offset settings you have made. The DC
test level should appear on screen. (If it does not return, the accuracy
check has failed for the current vertical scale, position, and offset
settings of the current channel.)
e. Measure the test signal: Press the Close button.
Read the measurement results at the measurement statistics Mean
measurement readout. Refer to the following figure.
Record the Mean in the Measurement Mean column. (See Table 3-5.)
