Clamp current can measure the actual power consumption of electrical
Clamp current meter to measure the current only part clamp meter can also measure the voltage, but also can only be measured;
The voltage measurement is simple, correct selection of AC voltage clamp meter stalls (about 220V), two two hole probes are respectively inserted into the socket can read voltage.
In addition to power voltage and current, and power factor, clamp meter can not measure. In general, the power factor of the computer is relatively high, and the power factor can be taken as 1.Power P=U*I.
The current measurement is trouble, you need to find a way to separate the line, power line and zero line separated by a wire clamp meter clamp, clamp meter AC current gear suitable position (about 1A~5A). You can read the current.
