OPERATION
APPLICATIONS
2-55. Transistor
Tester
2-56. The
transistor
tester
described
in
the
following
paragraphs
provides
approximate
test
information.
Beta
is
tested
usinga
VcEof2V
and an I cof
about
200
^uA.
This
transistor
tester is
useful for
checking
the
proper
operation of transistors and approximate
beta
values
for
comparative measurements.
2-57.
The transistor tester
fixture
is
described
in
Figure
2-13.
When
assembled and
coimected
to the
V/kO/S
and
the
COMMON
input connector,
the
Multimeter
can
be
used to
determine
the following
information
about
transistors:
•
Transistor
type (NPN
or PNP)
•
Defective
transistors
(shorted
or
open)
•
Collector-to-emitter
leakage
(Ices)
•
Beta
from
10
to
1000 in a
single
range.
2-58.
Transistor
type
is determined
by setting the switch
on
the
test fixture
to
BETA, setting
the
Multimeter to the
2
mS
range, and
observing the
display reading.
If
a low
reading
(<
0.010)
is
displayed,
reverse
the test fixture
at
the input connectors.
If
the
collector
of the transistor
is
now connected to the
COMMON
input
connector
the
transistor is a PNP type.
An NPN type
will have its
collector connected to the
V/kO/S
input connector.
2-59.
DEFECTIVE
TRANSISTORS
2-60.
If the
transistor
is
defective, the
following
indications
will appear,
regardless
of transistor
type
or
test position:
1. An
open
transistor
will
produce
a display
reading
of
0.001 or
less.
2. A shorted
transistor
will produce an
overrange
indication
on the
display.
