- Connect the test probes in parallel to the circuit or component under test.
- Read the voltage value on the display.
4.3. AC/DC Current Measurement
Caution: Never connect the meter in parallel to a voltage source when measuring current. This can damage the meter and the circuit.
- Connect the black test lead to the COM jack.
- For currents up to 600mA, connect the red test lead to the µA/mA jack. For currents up to 10A, connect the red test lead to the 10A jack.
- Rotate the Range Switch to the 'A~' (AC Current) or 'A-' (DC Current) position.
- Open the circuit where current is to be measured and connect the meter in series with the load.
- Read the current value on the display.
4.4. Resistance Measurement
- Connect the red test lead to the VΩHz jack and the black test lead to the COM jack.
- Rotate the Range Switch to the 'Ω' (Resistance) position.
- Ensure the circuit or component under test is de-energized.
- Connect the test probes across the component to measure its resistance.
