4. After test, immediately remove Micro Tester from microwave oven
— Holding Micro Tester upright, look straight down at pointer gauge for reading
5. Pour out water from Micro Tester after each test
Green Zone
 For OnCue™ microwave ovens, if pointer is between 1400 and 2400 (the green
area), the microwave oven wattage is acceptable
 For other microwave ovens, if pointer is between 1240 and 1816 (the green area),
the microwave oven wattage is acceptable
Red Zone
 For OnCue™ microwave ovens, if pointer is below 1474 or above 2483, the
microwave oven being tested needs immediate servicing
 For other microwave ovens, if pointer is below 1240 or above 1816, the
microwave oven being tested needs immediate servicing
 Note: If reading is in the red zone, test a second time to validate first reading
Magnetron Replacement
 For OnCue™ microwave ovens, a warning message will appear in the display if a
magnetron is not working
 For other microwave ovens, if pointer gauge is pointing to the number 736 in the
red zone (or very close to it), 1 of the 2 magnetrons is not working
Weekly Microwave Check
Other Microwave Ovens OnCue™ Microwave Oven
Tools required:
 Calibrated thermometer
 Measuring cup
 1-liter (33.8-oz.) wide-mouth plastic bowl with lid
Tools required:
 Calibrated thermometer
 Measuring cup
 Plastic microwave wattage testing bowl with lid
To check wattage:
1. Fill the bowl with exactly 1 liter (33.8 oz.) of cool
(approximately 70°F/21°C) tap water and tightly
cover with the lid
2. Insert the thermometer probe through the lid and
record the temperature
3. Remove the probe
4. Place the bowl in the center of the microwave
5. Close the door
6. Push the Wattage Check Button (gray “W”/green
“V”)
7. Remove the bowl and gently shake to mix the
water, to avoid “hot spot” readings
8. Insert the probe through the lid and record the
peak temperature reading
9. Subtract the first reading from the second reading
and multiply the difference by:
— 38.8 (Fahrenheit temperature readings)
— 70 (Celsius temperature readings)
To check wattage:

2. Insert the thermometer probe through the lid and
record the temperature
3. Remove the probe
4. Place the bowl in the center of the microwave
5. Close the door
6. Push the Wattage Check Button (gray “W”)
7. Heat the water for 30 seconds
8. Remove the bowl and gently shake to mix the
water, to avoid “hot spot” readings
9. Insert the probe through the lid and record the
peak temperature reading
10. Subtract the first reading from the second reading
and multiply the difference by:
— 77.6 (Fahrenheit temperature readings)
— 140 (Celsius temperature readings)
Example Wattage Check °F °C
Water temperature after heating 100°F 38°C
Subtract water temperature before heating -(65°F) -(18°C)
Difference 35°F 20°C
Multiply by x 38.8 x 70
Wattage output 1358 1400
Example Wattage Check °F °C
Water temperature after heating 91°F 33°C
Subtract water temperature before heating -(65°F) -(18°C)
Difference 26°F 15°C
Multiply by x 77.6 x 140
Wattage output 2017 2100
