Procedure For Measuring Radiation Leakage - Panasonic NE-C1153 Service Manual

temperature. (Record as T1)
2. Place the beaker in the center of cook plate.
Set the oven for High power and heat for exactly one
minute.
3. After completion of the heating cycle, stir the water again
with the thermometer and note the temperature. (Record as
T2).
The normal temperature rise (T2-T1), for these models should
be more than 16.8°F/9.4°C using the High power selection with
the oven operating at the specified line voltage.

12 PROCEDURE FOR MEASURING RADIATION LEAKAGE

WARNING
Check for radiation leakage after every servicing.
Should the leakage be more than 2 mW/square centimeter
(1mW/square centimeter for Canada) inform PASC, PSC, or PCI
immediately. After repairing or replacing any radiation safety device,
keep a written record for future reference, as required by D.H.H.S. and
Health and Welfare Canada regulation. This requirement must be
strictly observed. In addition, the leakage reading must be recorded on
the service repair ticket while in the customer's home.
NOTE:
The U.S. government
centimeter while in the customer's home. 2mw/square
centimeter stated here is Panasonic's own voluntary
standard.
12.1. Equipment
· Electromagnetic radiation monitor
· Glass thermometer 212°F or 100°C
· 600cc glass beaker
standard is 5mw/square
RATED OUTPUT
1100W (IEC-705)
12.2. Procedure for measuring
radiation leakage
Note before measuring
1. Do not exceed meter full scale deflection Leakage monitor
should initially be set to the highest scale.
2. To prevent false readings the test probe should be held by
the grip portion of the handle only and moved along the
shaded area shown in Figure right no faster than 1 inch/sec
(2.5cm/sec)
3. Leakage with the outer panel
5mw/square centimeter
4. Leakage for a fully assembled oven with door normally
closed less than 2mw/square centimeter
5. Leakage for a fully assembled oven [Before the interlock
switch (primary) is interrupted] while pulling the door less
than 2mw/square centimeter
1. Pour 275±15cc (9ozs ±1/2oz) of 20 ± 5°C (68 ± 9°F) water
