Abstract We put forward a method which connecting the WT210 digital power meter
and DR230 hybrid recorder, and with the helping of computer to inspect and record. We
can accurately measure the power of intermittent operated heating appliance such as
electric iron. At the same time we analysis the measurement uncertainty of the test
equipments and connection ways that used in the method, and in the end we give the
evaluation and expression on the test result.
