Fluke 8050A - 4-34. Linear Voltage Test; 4-36. dB Voltage Test

MAINTENANCE
LINEAR
VOLTAGE
TEST
4-34. Linear
Voltage
Test
4-35.
Use
the following procedure
to
verify the
proper
operation
of
the
ac
and
de
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 Voltage Test.
4-36.
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
/
kO/
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.
