6. Instruccions de funcionament

Before taking any measurement, ensure the test leads are correctly connected and the rotary switch is set to the desired function and range.

6.1 Mesurar DC Voltage (V=)

1. Introduïu el cable de prova vermell al VΩmAµA jack and the black test lead into the COM jack.
2. Turn the rotary switch to the desired V= (DC Voltage) range (e.g., 200mV, 2000mV, 20V, 200V, 600V). If the voltage is unknown, start with the highest range and decrease as needed.
3. Connecteu les sondes de prova al component o circuit que s'ha de mesurar.
4. Llegeix el voltage valor a la pantalla.

6.2 Mesurar AC Voltage (V~)

1. Introduïu el cable de prova vermell al VΩmAµA jack and the black test lead into the COM jack.
2. Turn the rotary switch to the desired V~ (Volum AC)tage) range (e.g., 200V, 600V).
3. Connecteu les sondes de prova a través del voltatge de CAtage font.
4. Llegeix el voltage valor a la pantalla.

6.3 Measuring DC Current (A=)

CAUTION: Never connect the multimeter in parallel with a voltage source when measuring current. This can blow the fuse or damage the multimeter.

1. For currents up to 200mA, insert the red test lead into the VΩmAµA jack. For currents up to 10A, insert the red test lead into the 10A MÀX jack. Always insert the black test lead into the COM jack.
2. Turn the rotary switch to the desired A= (DC Current) range (e.g., 2000µA, 20mA, 200mA, 10A).
3. Open the circuit where the current is to be measured and connect the multimeter in series with the circuit.
4. Llegiu el valor actual a la pantalla.
