5. Impostazione

5.1. Installazione della batteria

The VOLTCRAFT VC292 is powered by batteries. Ensure they are correctly installed before first use.

1. Spegnere il multimetro e scollegare tutti i puntali di prova.
2. Individuare il vano batteria sul retro del dispositivo.
3. Utilizzare un cacciavite per aprire il coperchio del vano batteria.
4. Insert 3x 1.5V AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Riposizionare il coperchio del vano batteria e fissarlo con la vite.

5.2. Collegamento dei puntali di prova

Il corretto collegamento dei puntali è fondamentale per ottenere misurazioni precise e sicure.

• Inserire il puntale di prova nero nel jack di ingresso "COM" (comune).
• Per la maggior parte dei volumitage, resistance, continuity, diode, and frequency measurements, insert the red test lead into the "VΩHz%" input jack.
• For current measurements (mA/µA), insert the red test lead into the "mAµA" input jack.
• For higher current measurements (A), insert the red test lead into the "A" input jack.

6. Istruzioni per l'uso

6.1. Accensione/spegnimento

Rotate the central function dial from the "OFF" position to any desired measurement function to turn on the multimeter. To turn off, rotate the dial back to the "OFF" position.

6.2. Selezione della funzione

The large rotary dial is used to select the desired measurement function. Press the "SEL" button to cycle through sub-functions within a single dial position (e.g., AC/DC voltage, resistenza/continuità/diodo).

6.3. Modalità di misurazione

Below are common measurement modes and their applications:

• Voltage Misurazione (V~ / V-):

  Select V~ for AC voltage o V- per DC voltage. Connect test leads in parallel with the circuit or component to be measured. Ensure the red lead is in the VΩHz% jack.
• Current Measurement (mAµA / A):

  Select the appropriate current range (mAµA or A). Connect the multimeter in series with the circuit. Ensure the red lead is in the corresponding mAµA or A jack. Attenzione: Never connect the multimeter in parallel for current measurement, as this can damage the device or blow the fuse.

• Misurazione della resistenza (Ω):

  Select the Ω function. Ensure the circuit is de-energized before measuring resistance. Connect test leads across the component.

• Continuity Test (audible beep symbol):

  Select the continuity function. The multimeter will emit an audible beep if the resistance between the probes is below a certain threshold, indicating continuity.
• Diode Test (diode symbol):

  Select the diode function. Use to test the forward voltagla caduta di un diodo.

• Misurazione della frequenza (Hz):

  Select the Hz function. Measures the frequency of an AC signal.

• Capacitance Measurement (capacitance symbol):

  Select the capacitance function. Measures the capacitance of a capacitor. Ensure the capacitor is fully discharged before testing.
• Volume senza contattotage(NCV):

  Select the NCV function. Hold the top of the multimeter near a live AC voltage source. The device will beep and the NCV indicator will light up if voltage viene rilevato.

• LoZ (Low Impedance) Measurement:

  This function helps to detect and eliminate ghost voltages. Refer to the display for the LoZ indicator.

7. Manutenzione

7.1. Pulizia

Pulisci la custodia con l'adamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is off and leads are disconnected before cleaning.

7.2. Sostituzione della batteria

When the battery indicator appears on the display, replace the batteries as described in Section 5.1. Use only 3x 1.5V AAA batteries.

7.3. Sostituzione del fusibile

If the multimeter fails to measure current, the fuse may be blown. Refer to the specifications for the correct fuse type and rating. Fuse replacement typically involves opening the battery compartment or a separate fuse compartment. Always replace with a fuse of the identical type and rating.

7.4. Conservazione

If the multimeter is not used for an extended period, remove the batteries to prevent leakage. Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
