3.2. Measurementofmicrowaveoutput
Theoutputpowerofthemagnetron canbedeterminedbyperforming IECstandard test
procedures. However,duetothecomplexityofIECtestprocedures, itisrecommendedtotestthe
magnetron using thesimplemethod outlinedbelow.
NecessaryEquipment:
*1literbeaker*Glass thermometer/ *Wristwatchor stopwatch
NOTE:
Check thelinevoltageunderload.Low voltagewill lowerthe
magnetron output. Take thetemperaturereadingsand heating time
as accuratelyas possible.
1. Fill thebeakerwithexactlyoneliteroftapwater.Stirthewater
using thethermometerand recordthewatertemperature.
(recordedas T1).
2. Place thebeakeron thecenterofglass tray. / Set theovenforHigh
powerand heat itforexactlyoneminute.
3. Stirthewateragainand readthetemperatureofthewater.
(recordedas T2).
4. Thenormal temperaturerise at High powerlevel foreachmodel is
as shownintable.
