Medición DC Voltage (VDC)

1. Conecte o cable de proba negro ao COM conector e o cable de proba vermello para o VΩmA jack.
2. Turn the function switch to the desired VDC range (e.g., 200mV, 2V, 20V, 200V, 600V). If unsure, start with the highest range and decrease as needed.
3. Conecte os cables de proba en paralelo a través do compoñente ou circuíto que se vai medir.
4. Le o voltago valor da pantalla LCD.

Medición AC Voltage (VAC)

1. Conecte o cable de proba negro ao COM conector e o cable de proba vermello para o VΩmA jack.
2. Turn the function switch to the desired VAC range (e.g., 200V, 600V).
3. Conecte os cables de proba en paralelo a través do voltaxe de CAtage fonte.
4. Le o voltago valor da pantalla LCD.

Measuring DC Current (ADC)

PRECAUCIÓN: Never connect the multimeter in parallel when measuring current. Always connect it in series with the circuit. Improper connection can damage the multimeter or the circuit.

1. Apague o circuíto.
2. For currents up to 200mA, connect the black test lead to the COM conector e o cable de proba vermello para o VΩmA jack.
