WARNING
°
Make
sure
to
check
the
microwave
leakage
after
repair
or
adjustment.
*
Always,
start
measuring
of
an
unknown
field
to
assure.
Safety
for
operating
personnel
from
microwave
energy.
*
Do
not
place
your
hands
into
any
suspected
microwave
radiation
field
unless
the
safe
density
level
is known.
e
Care
should
be
taken
not
to
place
the
eyes
in
direct
line
with
the
source
of
microwave
energy.
¢
Slowly:
approach
the
unit
under
test
funtil
the
radiometer
reads
an
appreaciable
microwave
leakage
from
the
unit
under
the
test.
:
Procedure
A)
Prepare
Microwave
Energy
Survey
Meter,
600cc
glass
breaker,
glass
thermometer
100°C
or
212°F.
B)
Pour
275cc
+
15cc
of
tap
water
initially
at
20+5°C
(68+
9°F)
in
the
600cc
beaker
with
a
inside
diameter
of
approx.
8.5cm.
C) Place it at the center of the tray and set it in a cavity.
D) Close the. door and operate the oven.
E)
Measure
the
leakage
by
using
microwave
energy
survery
meter
with
dual
ranges,
set
to
2,450
MHz.
—Measured
radiation
leakage
must
not
exceed
the
values
prescribed
below.
¢
Leakage
for
a
fully
assembled
oven
with
door
normally
closed
must
be
less
than
4mWicm?.
—When measuring the leakage, always use the
2 in (cm) space cone with probe. Hold the
probe perpendicular to the cabinet, door.
Place the space cone of the probe on the
door, cabinet, door seam, along the seam,
the door viewing window, the exhaust air
vents, the suction air vents.
—Measuring should be in a counter-clockwise
direction at a rate of 1 inch/sec. If the leak-
age of the cabinet door seam is unknow,
move the probe more slowly.
—When measuring near a corner of the door,
keep the probe perpendicular to the areas
making sure the probe end at the base of
the cone does not get closer than 2 inches
from any metal.
lf it does, erroneous reading may result.
