RMS
Converter
Offset Test
4-39,
Use the following
procedure to verify the
proper
dc
offset
of the
rms converter:
1.
On
the
UUT,
select
the
AC V
function,
any
range.
2.
On
the
UUT,
connect the
Low Ohms
Calibration
Lead between the
V/kH/S
and
COMMON
terminals.
3.
On
the
UUT,
measure and record the voltage
level
on
TPl
with the
DMM.
NOTE
Refer
to
Figure 4-3 for
the location of
TPl
and
TPl.
4.
Verify that the voltage
level at
TPl
(in
Step
3)
is
between -20
mV
and
20
mV.
5.
Measure
the voltage level
on TP2.
Verify that
the voltage
level
on
TP2
is
within
1
mV
of the
level
recorded
in
Step
3
(at
TPl).
