7.
When the countdown has finished, remove the container from the
cavity.
Immediately stir with a plastic implement and measure the water
temperature.
8.
Calculate the temperature rise of the water (end temperature
minus the start temperature).
The temperature rise should be 14.3°C (25.7°F) ±10% for the
1000W (1 magnetron) variant.
The temperature rise should be 28.5°C (51.4°F) ±10% for the
2000W (2 magnetrons) variant.
If the temperature rise is outside these limits check the micro-
wave circuit and components.
Replace the magnetron and/or high voltage diode board / rectifier
if required.
