Safety issues that should be paid attention to in measurement
1. Check the instrument comprehensively before measurement, and select the file correctly;
2. Wear gloves (insulated gloves or clean and dry wire gloves) during the test, and set up monitoring if necessary;
3. When it is necessary to change the gear for measurement, the wire should be pulled out from the jaws first, and then the wire should be clamped for measurement after changing the gear;
4. Do not measure the current on the bare conductor;
5. When measuring, pay attention to keep a safe distance from nearby charged objects (not less than 0.1 meters, be careful not to cause phase-to-phase short-circuit and phase-to-ground short-circuit, to prevent personal shock from electric shock;
6. It is not allowed to measure on the moving contact of the switch or the fuse;
7. After use, the gear should be adjusted to the current. If there is a cover, put it into the cover and store it in a dry, dust-free, corrosive gas-free, and vibration-free place.
