How to use a clamp meter right? Use should pay attention to what matters?

1 before measuring, should first check whether intact core rubber insulated clamp. The jaw should be clean and free of rust, and there is no obvious gap after closure.2 when measuring, the current should be measured and the proper range should be chosen. If you can't estimate, you can select a larger number of courses, then reduce the number of files to the appropriate gear. When converting the range gear, it must be done in the case of no electricity or under the opening of the jaw so as not to damage the meter.3 measurement, the measured wire should be placed in the middle of the jaw with jaw, face such as noise, should be re opening and closing time, still have the noise, should handle the joint surface, in order to make accurate readings. In addition, not at the same time around the two wires.4 measurement of the electric current is less than 5A, to get more accurate readings, when conditions permit, the wire around a few more laps, into the jaw measurement, the actual current value should be put into the meter reading divided by the number of jaw root wire.5 before and after each measurement, the switch of regulating current range should be placed in the most advanced position, so as not to damage the meter when measuring the frequency range without selecting the next time.
