Qparatien.
The
ac voltmeter
section of the
Model
339A Option 001
measures
the
true rms value
of
input
voltages from
. 1
mV full
scale
to 300V full
scale in fourteen
ranges.
Frequency range of
the meter
section is
1 0Hz to 80kHz for
the
. 1 mV and .3mV input
ranges,
and 1 0Hz
to
1
1
0kHz
for the .00
1
V to 300V input ranges.
