b. Set the Multimeter function to ACV (~ V) and range
to 2 V.
c. Set the AC Calibrator frequency to 40 Hz and adjust
the output amplitude for a Multimeter display of 1.0000.
d. Remove the jumper from the 1 Mf2 resistor. The
Multimeter display should indicate .4975 to .5025 verifying
an input impedance resistive component of 1 Mf2 ± 1%.
e. Maintain the AC Calibrator at 40 Hz and adjust the
output amplitude for a Multimeter display of 1.0000.
f. Change the AC Calibrator frequency to 3183 Hz. The
Multimeter display should indicate .7071 to 1.0000 verify
ing a shunt capacitance less than 100 pF.
