12.10 Microwave power determination
Microwave power available in the chamber can be determined by the 'water beaker test'.
This furnace does not have a mode stirrer, so the power level may vary within the chamber.
Power W = Delta T °C X 50. Delta T°C is for 2 X 1/2Ltr plastic beakers of water for 87*
second of microwave. The water temperature at the start of the test should be between
16°C and 22°C.
*Note: Allow for the 10 second delay after the timer starts before the MW power is switched
on.
