AC Current Measurement Note: 1) Turn the function dial to A~, , or position. The current measurement should be taken within 0°C~40°C. Do not suddenly 2) Press the trigger to open clamp jaws and fully enclose one conductor (only release the trigger, as the impact may change the reading for a short time. one conductor can be measured at a time).

When measuring resistance above 1MΩ, it is normal to take a few seconds to 7. Resistance Measurement (Picture 9) stablize reading. Use caution when working with voltage above AC 30Vrms, 42Vpeak or DC 60V. Those voltages may pose shock hazard. After completing the measurement, disconnect the test leads from the circuit under test.
