.
Werk
e . Change the Vc voltage to + . Adjust the Vc until the
negative peaks are at the center graticule line . Note the Vc
voltage .
f . The sum
of the
absolute values of the
voltages
in
steps d and e is the actual p - p voltage plus the offset of the
FG 5010 .

Check
that the p - p
amplitude is :
