A digital clamp meter is also called a clamp meter, which is an instrument that can clamp a wire and perform current detection without cutting the wire. The digital clamp meter can measure the current of the wire only by clamping the sheath of the wire, which makes the operation easier and safer.
How to use the digital clamp meter:
1. Mechanical zero adjustment must be performed before measurement;
2. Next, you need to choose the appropriate range, according to the principle of selecting a large range first and then a small range, or you can estimate it according to the nameplate value of the electrical appliance;
3. When using the minimum range for measurement, the reading may not be obvious. At this time, the wire to be measured needs to be wound a few turns, and the number of turns should be based on the number of turns in the center of the jaw. In this case The reading is: reading = indicated value × range / full deviation × number of turns;
4. When measuring, the wire to be measured should be located in the center of the jaws, and the jaws should be in a closed state, which can effectively reduce errors;
5. When the measurement is completed, switch the replacement switch to the maximum range.
Precautions for the use of digital clamp meters
1. The voltage of the line to be measured must be the rated voltage of the lion clamp meter;
2. When measuring the current of high-voltage lines, be sure to wear insulating gloves, insulating shoes and stand on insulating pads to ensure safety;
3. The jaws of the digital clamp meter must be closed tightly, and measurement cannot be performed under the condition of electrification.
