TheoutputpowerofthemagnetroncanbedeterminedbyperformingIECstandardtestprocedures.
However,duetothecomplexityofIECtestprocedures,itisrecommendedtotestthemagnetronusingthesimple
methodoutlinedbelow.
NecessaryEquipment:
*1literbeaker*Glassthermometer
*Wristwatchorstopwatch
NOTE:
Checkthelinevoltageunderload.Lowvoltagewilllowerthemagnetronoutput.Takethetemperaturereadings
andheatingtimeasaccuratelyaspossible.
1.Fillthebeakerwithexactlyoneliteroftapwater.Stirthewaterusingthethermometerandrecordthe
water’stemperature.(recordedasT1).
2.Placethebeakeronthecenterofglasstray.
SettheovenforHighpowerandheatitforexactlyoneminute.
3.Stirthewateragainandreadthetemperatureofthewater.(recordedasT2).
4.ThenormaltemperatureriseatHighpowerlevelforeachmodel,isasshownintable.
