Oven Tests
All ACP Microwave Oven Power Outputs are rated using the IEC705 standards Using the IEC705 test method
requires precision measurements and equipment that is not practical to be performed in the field. Using the following
tests will indicate if the oven is performing satisfactorily
Power Test
Set Up:
• Oven MUST be at room temperature for accurate results
• Service Test Mode: Both Magnetrons
Equipment:
• 1000ml test container
• Thermometer
Procedure:
1 Fill the test container with cool tap water, as close to 60°F (16°C) as possible
2 Using the thermometer, stir the water for 10 seconds; measure and record the temperature
3 Place the container of water in the center of the oven and close the door
4 Heat the water on full power for 33 seconds
5 At the end of the cycle, remove the container from the oven
6 Once again, stir the water for 10 seconds, take another measurement and record
7 Subtract the starting water temperature from the ending water temperature to obtain the temperature rise
8 If the temperature rise meets or exceeds the nominal microwave energy output rating found on the oven’s
model/serial tag, the test is complete
9 If the temperature rise fails to meet the minimum, test the incoming line voltage to verify it is correct
10 Before retesting replace the water as in Step 1
Repeat Steps 2 – 7 If the temperature rise fails to meet the minimum, the oven needs to be serviced
