D.MEASUREMENT WITH A FULLY ASSEMBLED OVEN

(1) After all components, including the outer panels, are fully assembled, measure for microwave energy leakage around the door viewing window, the exhaust opening and air inlet openings.

(2) Microwave energy leakage must not exceed the values prescribed below.

NOTES:

Leakage with the outer panels removed - less than 5mW/cm.sq. Leakage for a fully assembled oven (Before the latch switch (primary) is interrupted) with the door in a slightly opened position - less than

1mW/cm .sq.

E.NOTE WHEN MEASURING

(1)Do not exceed meter full scale deflection.

(2)The test probe must be removed no faster than 1 inch/sec (2.5cm/sec) along the shaded area, otherwise a false reading may result.

(3)The test probe must be held with the grip portion of the handle. A false reading may result if the operator’s hand is between the handle and the probe.

(4)When testing near a corner of the door, keep the probe perpendicular to the surface making sure the probe

is moved horizontally along the oven surface.

F.RECORD KEEPING AND NOTIFICATION AFTER MEASUREMENT

(1)After adjustment and repair of any microwave energy interruption or microwave energy blocking device, record the measured values for future reference. Also enter the information on the service invoice.

(2)Should the microwave energy leakage not be more than 1mW/cm.sq. after determining that all parts are in good condition, functioning properly and genuine replacement parts which are listed in this manual have been used.

(3)At least once a year, have the electromagnetic energy leakage monitor checked for calibration by its manufacturer.

G. POWER OUTPUT MEASUREMENT

(1)Fill the test beaker with 59 ˚F(15 ˚C) ~ 75 ˚F(24 ˚C) 1 liter tap water.

(2)Stir the water in the beaker with thermometer ( ˚F or ˚C) and measure temperature as T1.

(3)Place the beaker on the center of turntable.

(4)Set for one (1) minute and three (3) seconds and operate the oven at high power.

NOTE: The additional three (3) seconds is to allow the magnetron to begin generating power.

(5)When the heating is finished, stir the water again with thermometer and measure the temperature of water as T2.

(6)Subtract T1 from T2, this will give you the temperature rise.

(7)The microwave power output is within specification, if the temperature rise is as shown below:

 

Temperature Rise

 

 

 

Line Voltage

Degrees ˚F

Degrees ˚C

 

 

 

120 V

18.9 ~ 25.2

10.5 ~ 14

108 V

Min. 17.5

Min 9.7

(8)Power output will be influenced by line voltage of power supply. Consequently, correct power output must be measured within 120V AC ± 1 Volt while unit is operating.

SPECIAL TIP

• This oven used the button head screws.

Button Head (Torx style 2)

•When you remove the screws, using the tamper-resistant Torx driver have a pin-in-head.
