n
Set voltage of POWER SUPPLY to 60V and current of it to 0.8A.
o
Connect the output terminal of POWER SUPPLY to a DMM in 2A range in series. Hook up the DMM
with the input terminal of the electronic load.
p
Test the input terminal of the load by the 200V range of a DMM. Press SHIFT and C.V. MODE, then key in
