3.6 Utensil test
Never operate the microwave oven empty. The only exception is the utensil test described in the follow-
ing section. Some certain non-metal utensils may not be suitable for using in microwave. If you are not
sure whether your utensil is suitable for microwave, you can perform the following test.
1. Place the empty utensil to be tested into the microwave oven together with a microwave-compatible
glass filled with 250 ml water.
2. Operate the microwave oven at max power for 1 minute.
3. Check carefully the temperature of the utensil being tested. If it is warmed up, it is not suitable for
use in microwave.
4. Never exceed the operating time limit of 1 minute. If you notice arcing during 1 minute of operation,
stop the microwave. Utensils causing arcing are not suitable for use in microwave.
Following list is a general guide that would help you in selecting the right utensil.
