Three common questions about digital clamp meters
Through the use of digital clamp meters, we can know how to use digital clamp meters correctly;
It can help reduce the occurrence of faults and errors, while also effectively improving work efficiency and improving measurement accuracy.
Therefore, understanding how to use a digital clamp meter is very effective and convenient for our use.
How to use a digital clamp meter:
1. When using a high-voltage clamp meter, pay attention to the voltage level of the clamp ammeter. It is strictly forbidden to use a low-voltage clamp meter to measure the current of a high-voltage circuit.
When measuring with a high-voltage clamp meter, it should be operated by two people, and non-duty personnel should also fill in a work ticket when measuring;
When measuring, you should wear insulating gloves, stand on an insulating pad, and do not touch other equipment to prevent short circuit or grounding.
2. When observing the timing of the meter, special attention should be paid to keeping the distance between the head and the live parts. The distance between any part of the human body and the live body shall not be less than the entire length of the clamp meter.
3. When measuring on a high-voltage circuit, it is prohibited to use wires from the clamp-type ammeter to another meter for measurement.
When measuring the current of each phase of a high-voltage cable, the distance between the cable heads should be more than 300mm and the insulation should be good. The measurement can only be carried out when it is deemed convenient.
4. When measuring the current of low-voltage fusible fuses or horizontally arranged low-voltage busbars, each phase fusible fuse or busbar should be protected and isolated with insulating materials before measurement to avoid short circuit between phases.
5. When one phase of the cable is grounded, measurement is strictly prohibited.
Prevent personal injury from ground breakdown and explosion due to low insulation level of the cable head.
6. After the measurement of the clamp ammeter is completed, pull the switch to the range position to avoid inadvertent overcurrent the next time it is used; and it should be stored in a dry room.
