2. Per a la majoria de volumstage, resistance, continuity, diode, and capacitance measurements, insert the vermell cable de prova a la VΩHzCAP presa d'entrada.
3. For current measurements (mA/A), insert the vermell test lead into the appropriate current input jack (e.g., mA/A or 10A FUSIBLE), depending on the expected current level. Refer to the multimeter's faceplate for specific jack labels.

5. Instruccions de funcionament

5.1 Funcionament general

1. Encès/apagat: Rotate the central dial from the OFF position to any desired measurement function to turn the meter on. Rotate back to OFF to power off.
2. Selecció de la funció: Use the central rotary dial to select the desired measurement function (e.g., V~ for AC Voltage, V- per a volúmenes de corrent continutage, Ω per a la resistència).
3. Botó d'interval: Premeu el botó GAMMA button to manually select a measurement range if auto-ranging is not desired. Press again to cycle through ranges or hold to return to auto-ranging.
4. Botó HOLD: Premeu el botó MANTENIM per congelar la lectura actual a la pantalla. Premeu-la de nou per alliberar-la.
5. Botó de retroil·luminació: Press the backlight button (sun icon) to illuminate the display in low-light conditions.

5.2 Funcions de mesura

5.2.1 AC/DC Voltage Mesura

1. Gireu el dial giratori cap a V~ (Volum AC)tage) o V- (DC Voltagi).
2. Connect the black test lead to the COM terminal and the red test lead to the VΩHzCAP terminal.
3. Carefully touch the test probes to the points where voltage is to be measured (in parallel with the circuit).
4. Llegeix el voltage valor a la pantalla.

5.2.2 Mesura de corrent AC/DC

Precaució: Always ensure the circuit is de-energized before connecting the multimeter in series for current measurements. Incorrect connection can blow the fuse or damage the meter.

1. Gireu el dial giratori cap a A~ (corrent altern) o A- (DC Current).
2. Connecteu el cable de prova negre al terminal COM.
3. For currents up to 400mA, connect the red test lead to the mA/A terminal. For currents up to 10A, connect the red test lead to the 10A FUSIBLE terminal.
4. Obriu el circuit on es vol mesurar el corrent i connecteu el multímetre en sèrie.
5. Re-energize the circuit and read the current value on the display.

5.2.3 Mesura de la Resistència

1. Gireu el dial giratori cap a Ω (Resistance).
2. Connect the black test lead to COM and the red test lead to VΩHzCAP.
3. Ensure the component or circuit under test is de-energized.
4. Toqueu les sondes de prova a través del component o circuit.
5. Llegiu el valor de resistència a la pantalla.

5.2.4 Prova de continuïtat

1. Gireu el dial giratori cap a Continuïtat symbol (looks like a sound wave).
2. Connect the black test lead to COM and the red test lead to VΩHzCAP.
3. Assegureu-vos que el circuit que s'està provant estigui desenergitzat.
