b. Turn on the measurement Mean for the channel:
From the button bar, touch Measure and select the Ampl tab, More,
and then touch Mean to measure the mean of the current channel.
Press the X (Close) button.
NOTE.
When setting the Fluke generator to output >5 V, use the following
procedure:
Press the Aux button
Press the fourth soft key down (Selects the pulse with an exclamation point)
Set the amplitude to 5.3 or 5.5 V
Press the ->| key to select the pulse energy
Set the energy to 50J, and press the Output On key
Press the Trig Pulse soft key to trigger the pulse (this will generate a pulse
with 25 seconds duration).
Use the normal DC output for the 1 V, 3 V, and 5 V generator settings.
NOTE. If any of the voltages supplied by your generator are not calibrated,
verify those generator voltages using a digital multimeter, item 27.
c. Set the vertical scale: Set the vertical Scale to one of the settings listed in
the following table that is not yet checked, starting with the first setting
listed.
