The results shown in Table 1 are the expected energy output in kW-sec obtained from the load power, 1.2 kW and time and energy output from measurement that is displayed by LCD after every 20 sec. A certain amount of power is supplied to the load, this power is maintained over a certain period of time and the energy consumption is calculated and finally displayed. The tests were done over a 3 minute period, measurements were taken every 20 sec and a very high accuracy level is observed particularly after longer periods of time.
