Infinite Wire Harness Test continuity of wires Indicates continuity Power Test (Traditional Test Method) Test equipment required is Amana power test kit R0157397(Fahrenheit), or Menumaster power test kit M95D5 (Celsius). 1. Fill the plastic container to the bottom of the 1000 ml. line with cool tap water. 2. Using the thermometer; stir the water, measure and record the water temperature. Initial water temperature should be approximately 60°F (20°C). 3. Place container on the center of the oven shelf and heat the water for 62 seconds. NOTE: Use a watch second hand, not the oven timer. 4. Stir the water, measure and record the temperature of the water after heating time is complete. 5. Subtract the starting water temperature (Step 2), from the ending water temperature (Step 4) to obtain the temperature rise. 6. See the Temperature Chart provided below. NOTES: The IEC-705 test method requires precision measurements and equipment. It is not practical to perform the IEC test in the field. To convert the traditional power test results to the approximate IEC-705 rating, take the traditional power test results and add 100 watts per magnetron for the unit being tested. Example: 930 watts output using the traditional power test for model RCS10MP + 100 watts (1 magnetrons X 100 watts) 1030 Approximate IEC-705 results Always perform power test three times for accuracy, changing the water after each test is performed. Variation or errors in the test procedure will cause a variance in the temperature rise. Additional power tests should be made if temperature rise appears marginal. Low line voltage will cause lower temperature rise.
