NOTE.
When setting the Fluke generator to output >5 V with the
instrument termination set to 50 Ω, 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 generator
settings ≤5 V at termination setting 50 Ω and for any voltages at a
termination setting of 1 MΩ.
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:
