SECTION 72
OPERATOR'S SECTION
2-1 GENERAL
The
Model
60004
Mutual
Conductance
tube
tester
can
test
vacuum
tubes,
rectifier
tubes,
thyratrons,
transistors,
diodes,
and
rectifiers.
It
can
measure
Mutual
Conductance,
Grid
Current,
Filament
Continuity,
Shorts,
and
Leakage
currents
for
all
vacuum
tubes.
It
also
provides
"GOOD-BAD"'
quality
tests
for
NPN
and
PNP
transistors
and
a
forward
conduction
efficiency
test
on
semiconductor
diodes.
2-2 INSPECTION AND ADJUSTMENT
Before
placing
the
Model
6000A
into
operation,
visually
inspect
it
for
any
physical
damage
such
as
broken
or
loose
knobs,
broken
meter
cover,
etc.
All
damage
claims
must
be
made
to
the
carrier
within
48
hours
of
receipt
of
the
equipment.
A
damage
report
sheet
is
included
with
this
manual
giving
detailed
instructions
for
filing
a
damage
report.
All
calibration
controls
have
been
preset
at
the
factory,
therefore
no
adjustment
of
the
Model
6000A
is
necessary
prior
to
operation.
2-3
FRONT
PANEL
CONTROLS
AND
CONNECTORS
Personnel
should
become
familiar
with
the
controls
and
operating
features
of
the
Model
6000A
before
attempting
to
put
it
into
operation.
The
front
panel
controls
are
explained
below:
a.
FILAMENT
VOLTAGE
SELECTOR
-
20
position
switch
-
per-
mits
selection
of
filament
voltage
to
correspond
with
data
on
roll
chart.
To
be
positioned
according
to
roll
chart
data.
b.
POWER
LINE
ADJUST
-
A
rheostat
that
has
two
purposes:
First,
it
acts
as
an
ON-OFF
switch,
and
second,
it
provides
standardization
of
test
voltages.
c.
BIAS
CONTROL
-
Permits
adjustment
of
the
bias
voltage
(from
0-40
volts)
for
the
tube
under
test.
d.
SHUNT
CONTROL
-
Controls
the
sensitivity
of
the
test
meter.
e.
FUNCTION
SELECTOR
SWITCH
-
8
position
switch.
Permits
selection
of
the
proper
test
circuit
for
the
different
tube
types
under
test.
To
be
positioned
according
to
roll
chart
data.
