How to check the steam-sensor function.

To determine if this function is working ok, do the following:
1. Place a water load of 150 cc in the oven.
2. Press the sensor re-heat pad.
3. Press start.
Note: Steam is normally detected approximately 1.5 to 4 minutes after
pressing power. This period is named "The detection period T1".
After going through this period, the unit automatically jumps to another
period called "The remaining cooking time period T2". The T2 time ranges
from 8 seconds to 23 seconds.
4. "The steam sensor function" is normal, if after jumping to the T2 period,
the "remaining cooking time" (8sec. ~ 23 sec.) appears in the display
window.
