Page 108 10 Tests Microwave Leakage test Follow these instructions when measuring:  Make sure that the survey meter you are using has been calibrated and is suitable for measuring frequencies of 2,450 MHz.  Do not exceed meter full scale deflection. The leakage meter should initially be set to the highest scale, then adjusted down as necessary to ensure that low readings are measured on the most sensitive range.
Page 109 10 Tests Move the survey meter probe across all casework joins and vent areas including those marked in yellow, shown opposite. When the magnetron circuit stops after 30 seconds, change the water and re-select the test to continue. Select the red ‘X’ on the display to stop the test at any time. Readings must be below 5 mW/cm².
Page 110 10 Tests Temperature Control test: measuring the cavity temperature NOTE: Re-calibrating the temperature sensor / thermocouple with the SRB is normally only required when the thermocouple has been replaced or the appliance is under or over cooking. Place the probe of a temperature reader onto a heat sink or a metal plate in the centre of the oven cavity and close the door.
Page 111 10 Tests If the temperature reading is different to the maximum set point, scroll up to select TEMP. COMP. (Temperature Compensation) and enter the password. Enter the figure from the temperature reader on the keypad and select OK to calibrate the SRB to the temperature sensor (ther- mocouple).
Page 112 10 Tests If the temperature reading is unstable: Disconnect and isolate the appliance from the electricity supply. Take protective measures to ensure the power cannot be switched on again. Allow the appliance to cool down. Remove the side and top panels of the casing. Check the cavity temperature sensor wire and connections.
