1. Set the Function/Range switch to the A=/A\~ position.
2. Press the trigger to open the transformer jaws and clamp them around a conductor. Jaws should be completely closed before taking a reading.
3. The most accurate reading will be obtained by keeping the conductor across center of the transformer jaws.
4. The reading will be indicated on the display.
5. Reduce the range setting if set too high until a satisfactory be st resolution reading is obtained.

Resistance measurements

1. Set the Function/Range switch to the "Ω" position.
2. Turn off power to the circuit under test. External Voltage across the components causes invalid reading.
3. Connect the red test lead to the "VΩ" jack and the black test lead to the "COM" jack.
4. Connect the test leads to the points of measurements and read the value from the display.

Continuity measurements

1. Set the Funtion switch to the "◆" position.
2. Turn off power to the circuit under test. External Voltage across the components causes invalid reading.
