5.3 Ìwọ̀n Ìṣàn DC (A–)

Used for measuring direct current flowing through a circuit.

1. Pataki: Disconnect power to the circuit before connecting the multimeter in series.
2. Set the rotary switch to the desired DC Current (A–) range (e.g., 2000uA, 20mA, 200mA, 10A).
3. Insert the red test lead into the appropriate current input jack ('VΩmA' for low current, '10A MAX' for high current).
4. Connect the multimeter in series with the circuit, ensuring the current flows through the meter.
