The
M3 readout display (RMS voltage) should
appear in the upper graticu le division. and the
vertical
sensitivity in volts
per
division should
appear

the
lower
graticule division.
8.
The
readout should read
within
the limits of
.000
V
to
.001 V, and
the
vertical sensitivity
should
read
100
mV
.
9.
