5.1. Akumuliatoriaus įdėjimas

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

1. Įsitikinkite, kad multimetras yra išjungtas.
2. Suraskite akumuliatoriaus skyrių įrenginio gale.
3. Baterijų skyriaus dangteliui atidaryti naudokite atsuktuvą.
4. Įdėkite 4 AAA baterijas, laikydamiesi teisingo poliškumo (+/-), kaip nurodyta skyrelio viduje.
5. Saugiai uždarykite akumuliatoriaus skyriaus dangtelį.

5.2. Bandymo laidų prijungimas

Tinkamas bandymo laidų prijungimas yra labai svarbus norint atlikti tikslius ir saugius matavimus.

• Insert the black test lead into the “COM” (Common) jack.
• Daugumai tūriųtage, 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. Naudojimo instrukcijos

6.1. Maitinimo įjungimas/išjungimas

Paspauskite Galia button (red circle with line) to turn the multimeter on or off.

6.2. Funkcijos pasirinkimas

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

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

6.3. Matavimo režimai

Ensure test leads are correctly inserted for the desired measurement.

6.3.1. ttagMatavimas (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 matavimas.
3. Jei reikia, paspauskite SEL to switch between AC and DC voltage.
4. Prijunkite bandymo zondus lygiagrečiai prie matuojamos grandinės arba komponento.

6.3.2. Srovės matavimas (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. Jei reikia, paspauskite 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.
