2 Calibrator: Select a 0.001 volt ae signal at
I kHz
(use the
"Wideband" output on the Fluke 5700A).
3
External Multimeter: Select the 10 Vde range with 5\.2 digits of
resolution.
4 Remove only the top cover from the HP 3400B (it is important
that you
do
Mt remove the side or bottom covers). Adjust
Ral6
until the de voltage measured at the rear-panel de output jaek is
within the limits shown in the table above.
Note Since the full scale and tenth scale aqjustments are interdependent,
you slwuld repeat both aqjustments again. Repeat the procedures again,
slorting with step 1 for the full scale aqjustment, on page
