Performance Test; Display Test; Resistance/Conductance Test - Fluke 8010A Instruction Manual

MAINTENANCE
PERFORMANCE
TEST
4-27.
PERFORMANCE
TEST
4-28.
The
performance
test
compares
the
performance
of
your Multimeter with
the
list
of
specifications
given
in
Section
1.
This
test
is
recommended
for
incoming
inspection, as
a preventive
maintenance
check,
and
to
verify the specifications.
If
the instrument
fails
any
part of
the
performance
test,
calibration
and/or
repair
is
indicated.
4-29.
Allow the instrument
to stabilize
and perform
the
test
at
an ambient temperature
of
23°C
+5°C
(73°
±9°F). During
the
performance
test
(and
the calibration
procedure)
your Multimeter
is
referred to as the
UUT
(Unit
Under
Test).
4-30.
Display Test
4-31.
Use
the
following procedure
to verify
the proper
operation of
the
LCD;
1.
On
the
UUT,
set
the
POWER
switch
to
the
ON
position.
2.
On
the
UUT,
select
the
kH
function,
2000
kfl
range. Verify that the overrange
indication
(1)
appears
on
the
LCD.
3.
On
the
UUT,
select
the
V
DC
function.
Verify a
display
reading of
"000".
4.
Connect
the
Low Ohms
Calibration
Lead
between
the
V/kO/S
and
COMMON
input
terminals.
5.
Refer
to
Table
4-2, verify
the
proper
position of
the
decimal point
for
each range shown.
6.
Remove
the
Low Ohms
Calibration Lead.
7.
Connect
the
HI
output
of the
DMM
Calibrator
to the
V/kD/S
input of the
UUT.
Connect
the
LO
output of the
DMM
Calibrator to the
COMMON
input
termmal
of the
UUT.

Use
the following procedure
to verify the
proper
operation
and performance
of the resistance
and
conductance
ranges:
1.
On
the
UUT,
connect
the
Low Ohms
Calibration
Lead
between
the
V/kfl/S and
COMMON
input
terminals.
2.
On
the
UUT,
select
the
kH
function,

range. Verify that the display reading
is
between
"00.0" and
"00.2".
3.
Remove
the
Low Ohms
Calibration Lead.
4.
On
the
UUT,
select the
S
function 200
nS
range.
Verify that the display reading
is
between
"00.0"
and "01.0".
5.
Connect
the
HI
output
of the
DMM
Calibrator
to the
V/kO/S
input terminal of
the
UUT.
Connect
the
LO
output
of the
Multimeter
Calibrator to the
COMMON
input terminal
of
the
UUT.
6.
For each
step in Table
4-3, select the range
shown and
adjust the
DMM
Calibrator
to the
required
UUT
resistance input,
then
verify that
the
UUT
display reading
is
within
limits.
