5. Podešavanje

5.1. Instalacija baterije

The VAR TECH V92S requires 4 AAA batteries for operation. If batteries are not pre-installed, or if replacement is needed:

1. Provjerite je li multimetar isključen iz napajanja.
2. Pronađite odeljak za baterije na poleđini uređaja.
3. Koristite odvijač da otvorite poklopac pretinca za baterije.
4. Umetnite 4 AAA baterije, pazeći na ispravan polaritet (+/-) kao što je naznačeno unutar odjeljka.
5. Sigurno zatvorite poklopac odjeljka za baterije.

5.2. Povezivanje ispitnih vodova

Pravilno spajanje mjernih kabela je ključno za tačna i sigurna mjerenja.

• Insert the black test lead into the “COM” (Common) jack.
• Za većinu volumenatage, resistance, continuity, capacitance, frequency, and temperature measurements, insert the red test lead into the “INPUT” jack.
• For current measurements (mA/A), insert the red test lead into the “mA/A” jack.

Figure 5.1: The input jack prompt light feature. When turning on or changing ranges, the corresponding input socket light flashes to indicate where to insert the probe.

6. Uputstvo za upotrebu

6.1. Uključivanje/isključivanje

Pritisnite Snaga button (red circle with line) to turn the multimeter on or off.

6.2. Odabir funkcije

The V92S features an auto-ranging function, automatically detecting the measurement type in “SMART” mode. For specific functions, use the SEL i FUNC dugmad:

• Dugme SEL (Odabir): Used to switch between different measurement types within a primary mode (e.g., AC Voltage i DC Voltage, or Diode and Continuity).
• FUNC (Function) Buttons: Used to directly select specific measurement functions like Capacitance, Frequency, or Temperature.

6.3. Načini mjerenja

Ensure test leads are correctly inserted for the desired measurement.

6.3.1. svtagMjerenje (AC/DC)

1. Insert the red lead into the “INPUT” jack and the black lead into the “COM” jack.
2. Turn on the multimeter. It will typically default to auto-ranging voltage mjerenje.
3. Ako je potrebno, pritisnite SEL to switch between AC and DC voltage.
4. Connect the test probes in parallel to the circuit or component to be measured.

6.3.2. Mjerenje struje (AC/DC)

1. Insert the red lead into the “mA/A” jack and the black lead into the “COM” jack.
2. Turn on the multimeter. The device automatically enters the current measurement function when the probe is inserted into the mA/A socket.
3. Ako je potrebno, pritisnite SEL to switch between AC and DC current.
4. Connect the test probes in series with the circuit to be measured.

Figure 6.1: Automatic identification of current measurement. The multimeter automatically adjusts to the current measurement function when the probe is inserted into the mA/A socket.

6.3.3. Resistance, Capacitance, Frequency, Temperature, Diode, Continuity

For these measurements, ensure the red lead is in the “INPUT” jack and the black lead in the “COM” jack. Use the SEL or FUNC buttons to select the desired mode. Connect probes to the component or circuit as appropriate for each measurement type.

6.3.4. NCV (Non-Contact Voltage) Test

NCV funkcija omogućava detekciju AC volumnatage bez direktnog kontakta sa provodnicima.

1. Select the NCV function using the appropriate button.
2. Bring the top of the multimeter near the conductor or outlet.
3. The instrument will emit an audible beep and the alarm indicator light will illuminate when AC signals are detected. A “-H” display indicates a strong signal, while “-L” indicates a weak signal.

8. Otkrivanje problema

If you encounter issues with your VAR TECH V92S, refer to the following common problems and solutions:

• Bez prikaza: Provjerite jesu li baterije ispravno postavljene i uvjerite se da nisu ispražnjene. Zamijenite ih ako je potrebno.
• Netačna očitanja: Verify test lead connections. Ensure the correct measurement function is selected. Check if the fuse is intact for current measurements.
• “OL” or Overload Indication: The measured value exceeds the range of the selected function. Select a higher range if available, or ensure the input is within the multimeter’s capabilities.
• “FUSE” Display: The fuse has blown. Refer to Section 7.3 for fuse replacement.

If the problem persists, contact VAR TECH customer support for assistance.
