Full
Range Checks (1mV

at
1MHz)
N.B. These
verification
checks
are
not
fully traceable.
The
verified
output values
of
IV
on
the
IV
Range, and
lOV
on
the
lOV
Range;
are
used
to
measure
the
4708
linearity
error
at
IV
on
the
lOV
Range.
From
the
linearity
measurement
a
T0%
of Range'
Linearity
and
Scaling Factor
'C
is
derived.
This
factor
is
subsequently
used
to correct the
4708
output
setting at
10%
of
range,
to
standardize
a
DVM
for verification
of
the
next range
down.
