Step Activities
1 Put Inspection - 200cc A cup of w ater on the Tray center.
* If sensing valeue is less them (or equal) to 15(Hexadecimal), repeat 2~3times from
step 1 to step 4 until display show s more than 16(Hexadecimal).
If you fail to have more than 16(hexadecimal), replace Ass'y Sensor PCB or M agnetron.
Then;
-. Leave unit in room temperature about 20 minutes for cooling.
-. Calibrate Easy Sensor from the beginning step of calibration method.
-. Check Easy Sensor Voltage again.
