Linear Voltage
T
est
4-35.
Use
the following procedure
to verify
the proper
operation of the ac
and
dc voltage
measurement
functions:
1.
Connect
the
DMM
Calibrator
to
the
8050A
as
follows:
HI
to the
V
/
kO/
S input
connector and
LO
to the
COMMON
input connector.
2.
For each
step
in
Table
4-4, select
the switch
positions
shown and
adjust the
DMM
Calibrator to the required
8050A
voltage input
level
and
frequency,
then
verify that the
8050A
display reading
is
within
limits.
3.
This concludes the Linear
Voltage
Test.
If
desired
proceed
directly to the
dB
V
oltage Test.

dB
Voltage Test
4-37.
Use
the
following procedure
to verify the
proper
operation of
the
dB
voltage
measurement
function:
1.
Complete
the Linear Voltage Test.
2.
Select the
AC
dB
function,
200mV
range.
3.
Connect
the
DMM
Calibrator
to the
8050A
as
follows:
HI
to the
V/kn/S
input connector and
LO
to the
COMMON
input connector.
4.
For each
step
in
Table
4-5,
adjust the
DMM
Calibrator to the required
8050A
voltage input
level
and
frequency, then
verify that the 8050A
display reading
is
within
limits.
