Figure
2-8 describes
how
to
operate your
Multimeter
for
conductance measurements.
When
S=l/n
is
selected,
three ranges of
measurements
are
available, 2
mS,
20
juS,
and
200
nS.
To
select
a range,
press
both range switches (above the grey-shaded
area)
simultaneously.

Diode Test
2-35.
Figure
2-9
describes
how
to operate
your
Multimeter for
diode
tests.
The
three resistance ranges
with the diode
symbol
beside the
range value provide a
measurement voltage
sufficient to
cause a
silicon
junction
to
conduct.
These ranges
(2 kfi,
200
kfl,
and
20
MH)
can
be used to
check
silicon
diodes
and
transistors.
The
2
kO
resistance
range
is
the preferred diode
and
transistor
testing
range
and
is
labeled with the
largest
diode
symbol
(-N-).
For a
silicon
diode, the
typical
forward
bias
voltage (on the 2 kfl
-W-
range)
is
0.6V.
A
reversed
bias
silicon
diode should display the overrange indicator (on
the
2
kfl
"I—
range).

INITIAL
CHECKOUT PROCEDURE
2-3 7
.
The
following procedure, allows
you
to verify that
the
Multimeter
is
operating correctly for
most
functions.
The
only
test
equipment required
is
a
set of
test
leads
and
access to a standard
wall
socket..
This procedure checks
for
general operation only
and
is
not intended
to verify
instrument accuracy.
Performance
tests
and
calibration
adjustments are contained
in
Section 4 of
this
manual
for
the
purpose
of Testing
and
correcting
instrument
accuracy.
2-38.
Use
the following
procedure
to verify
that
most
of
the functions of
your Multimeter
are
operating
correctly:
1.
Select the
AC V
function
on
the
Multimeter.
2.
Set the
Multimeter
to
the
750V
range.
WARNING
THE LOCAL
LINE
VOLTAGE
IS
BEING
MEASURED
IN
THE FOLLOWING
STEP.
DO
NOT TOUCH THE PROBE
TIPS
OR ALLOW
THE PROBE
TIPS
TO
COME
IN
CONTACT
WITH
EACH OTHER
WHILE
PREFORMING
THE FOLLOWING
STEP.
3.
Insert
the
probe
tips
into
a standard wall
socket.
Note
the
preceding warning.
The
display
should read the local
line
voltage.
4.
Momentarily
set
the
instrument to the
20V
range.
The
overrange indicator
should be
displayed.
5.
Remove
the
test leads
from the wall socket.
