l Make sure to check the microwave leakage before and after repair of adjustment.
l Always start measuring of an unknown field to assure safety for operating

personnel from microwave energy.

l Do not place your hands into any suspected microwave radiation field unless the

safe density level is known.

l Care should be taken not to place the eyes in direct line with the source of

microwave energy.

l Slowly approach the unit under test until the radiometer reads an appreciable

microwave leakage from the unit under the test.

A) Prepare Microwave Energy Survey
   Meter, 600cc glass beaker, and glass
   thermometer 100°C (212°F ).

B) Pour 275cc ±15cc of tap water initially

at 20 ± 5 °C (68 ± 9°F) in the 600 cc
glass beaker with an inside diameter of
approx. 95 mm(3.5 in.).

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 Survey Meter with
   dual ranges, set to 2450MHz.
- Measured radiation leakage must not

exceed the value prescribed below.
Leakage for a fully assembled oven
with door normally closed must be less
than 4mW/cm2.

- When measuring the leakage, always use the 5 cm (2 in.) space cone with probe.

Hold the probe perpendicular to the cabinet and door. Place the space cone of the
probe on the door, cabinet, door seem, door viewing screen, the exhaust air vents
and the suction air vents.

- Measuring should be in a counter-clockwise direction at a rate of 1 in./sec. If the

leakage of the cabinet door seem is unknown, 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 in. from any metal. If it does not, erroneous reading may result.
