Three Common Problems of Digital Clamp Meter
By using the digital clamp meter, we can know how to use the digital clamp meter correctly;
It can help to reduce the occurrence of faults and errors, and can also effectively improve work efficiency and improve measurement accuracy.
Therefore, it is very effective and convenient for us to understand how to use the digital clamp meter.
How to use the digital clamp meter:
1. When using a high-voltage clamp meter, attention should be paid to the voltage level of the clamp ammeter, and it is strictly forbidden to use a low-voltage clamp meter to measure the current of the 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 for measurement;
Wear insulating gloves when measuring, stand on an insulating pad, and do not touch other equipment to prevent short circuit or grounding.
2. When observing the timing of the watch, special attention should be paid to keeping the distance between the head and the charged part. The distance between any part of the human body and the charged body should not be less than the entire length of the clamp meter.
3. When measuring on the high-voltage circuit, it is forbidden to use wires to connect the clamp ammeter to the meter for measurement.
When measuring the current of each phase of the high-voltage cable, the distance between the cable ends should be more than 300mm, and the insulation should be good, and the measurement can only be carried out when it is considered convenient.
4. When measuring the current of low-voltage fusible fuses or horizontally arranged low-voltage busbars, the fusible fuses or busbars of each phase 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, it is strictly forbidden to measure.
Prevent personal injury due to ground breakdown explosion due to low insulation level of the cable head.
6. After the measurement of the clamp ammeter, pull the switch to the limit position to avoid accidental overcurrent during the next use; and it should be stored in a dry room.
