EXCESSIVE MICROWAVE ENERGY
(a) Do not operate or allow the oven to be operated with the door open.
(b) Make the following safety checks on all ovens to be serviced before activating the magnetron or other
microwave source, and make repairs as necessary :
(1) Interlock operation, (2) proper door closing, (3) seal and sealing surfaces (arcing, wear, and other damage),
(4) damage to or loosening of hinges and latches, (5) evidence of dropping or abuse.
(c) Before turning on microwave power for any service test or inspection within the microwave generating
compartments, check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity,
and connections.
(d) Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and
transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before
the oven is released to the owner.

Ovens.
It requires that the power density of the microwave

the owner should be told not to use the microwave oven

If a microwave oven is found to operate with the door open,
report to Dept. of Service, the manufacturer and CDRH*
immediately. Also tell the owner not to use the oven.
*CDRH : Center for Device and Radiological Health.

in measurement with IEC, when measured with the following
power output.
(1) Fill two beakers (glass or plastic) with each one liter of
tap water (about 20°C) and measure the water temperature.
(Use a thermometer with a 1/10 degree gauge).
(2) Place the beakers side by side in the center of the glass tray.
(3) Close the door, set the “TIME” for two minutes. (“200” in
the display window). Touch the “START” key and heat
the water exactly for two minutes.
(4) Take the beakers out, immediately stir the water and
measure the water temperature respectively.
(5) Calculate the temperature rise of water in each beaker.
Then calculate the average value of two temperature rises.
Output power can be calculated by the equation :
Power Output (W) = 70 x ∆t
Where ∆t is an average temperature rise in degrees
Centigrade.
(6) Power Output shall be in the following range :
(7) Power Output is affected by the line voltage under load.
For correct Power Output measurement, the line voltage
under load must be 120±1 volts.
