How to use the clamp meter
1. Perform mechanical zero adjustment before measurement;
2. Determine the appropriate range according to the range selection principle of "large first and then small", or estimate according to the nameplate of the electrical appliance;
3. Use the minimum range. When the reading is not obvious, you need to wind the wire under test a few turns, and the number of turns in the center of the jaw shall prevail. At this time, reading = indicated value × range / full deviation × number of turns;
4. In order to effectively reduce the error, the conductor to be measured should be located in the center of the jaw during measurement, and the jaw should be tightly closed;
5. After the measurement, turn the transfer switch to the maximum range;
