b. Turn on the meas
urement Mean for the channel:
From the button bar, touch Measure and select the Ampl tab, More,
andthentouch
Mean to measure the mean of the current chan nel.
Press the X (Close) button.
NOTE. When s
etting 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 en
ergy 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. I
f any of the voltages supplied by your generator are not calibrated,
verify those generator voltages using a digital multimeter, item 27.
c. Set t
he 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.
