Precautions and daily maintenance of clamp meter
1. When measuring current, disconnect the test leads from the meter and place your finger behind the touch shield.
2. When measuring current, only the current of one phase wire can be measured at a time, and the wire to be tested should be placed in the center of the clamp window, and multi-phase wires cannot be clamped into the window for measurement.
3. When measuring voltage, use the test probes with your fingers behind the finger guard.
4. When measuring resistance and continuity, make sure the circuit is powered off and all capacitors are discharged.
5. Use the correct terminal, function file and range when measuring. Before measuring with clamp meter, you should first estimate the magnitude of the measured current, and then decide which range to use. If it is impossible to estimate, you can first use the maximum range file and then change it to a smaller one to get an accurate reading. It is not possible to use the low current gear to measure large currents. to prevent damage to the meter
6. The voltage of the circuit under test cannot exceed the value marked on the clamp meter, otherwise it may easily cause a grounding accident or cause an electric shock hazard
