Clamp Multimeter the use of the following:
1, in the measurement of the work of the equipment in the work of the current, the clamp mouth open, and then the power supply to be measured by a wire stuck in the jaws of the jaws (can not be carded at the same time, two or more lines) and then close the jaws, the clamp multimeter can be displayed on the current value. The value of the current can be displayed on the clamp multimeter.
2, measurement to ensure that the contact surface between the two jaws tight. Start with a large range, according to the reading and then select the appropriate range, which can improve the accuracy of the reading. If it is a pointer type clamp multimeter, you should try to let the pointer close to the slow scale.
3, the nameplate of each device are labeled with its rated current, in the measurement can be used as a reference. If the measured current and the nameplate on the rated current difference is very large, indicating that the equipment has a fault, to analyze the causes of troubleshooting.
