OUTPUT POWER TEST PROCEDURE

MICROWAVE OUTPUT POWER (IEC-705)

The power output of this oven is rated using the method specified by IEC-705. Full details of how to carry out this

procedure can be found in the Sharp Technical Training notes which is available from Sharp Parts Centre

(part number SERV-LITMW01).

The IEC-705 procedure must be carried out using laboratory-type procedures and equipment. These require-

ments make the procedure unsuitable for routine performance checks.

Note: The following test method gives an indication of the output power only, it cannot be used to establish the

actual/ rated output power. If the true output power is required, then the IEC-705 test method must be used.

Alternative simplified method:

1. Place 2 litres of cold water (between 12°C and 20°C) in a suitable container.

2. Stir the water and measure the temperature in °C. Note temperature as T1.

3. Place the container in the microwave and heat the water for 2 minutes on full power.

4. When the 2 minutes is completed, remove the container and stir the water. Note the water temperature as T2.

5. Calculate the output power using the following formula:

R.F. Power Output = (T2 - T1) x 80.

MICROWAVE LEAKAGE TEST

This oven should be tested for microwave leakage on completion of any repair or adjustment, following the

procedure described in the Sharp Technical Training notes (part number SERV-LITMW01). The maximum

leakage permitted in BS EN 60335-2-25 is 50W/m

any significant leakage, therefore, any leakage which is detected should be investigated.

It is essential that only leakage detectors with current calibration traceable to the National Physical Laboratories

are used.
