d. Display the test signal:
HPress VERTICAL MENU. Press the main-menu button Position.
HUse the keypad to set vertical position to –5 divisions (press –5, then
ENTER, on the keypad). The baseline level will move off screen.
HPress the main-menu button Offset.
HUse the keypad to set vertical offset to the positive-polarity setting
listed in the table for the current vertical scale setting. The baseline
level will remain off screen.
HSet 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 doesn’t return, the DC
accuracy check has failed for the current vertical scale setting of the
current channel).
e. Measure the test signal: Press CLEAR MENU. Read the measurement
results at the Mean measurement readout. See Figure 1–6.
