2. Turvallisuustiedot

Always adhere to basic safety precautions when using this multimeter to prevent personal injury or damage to the instrument. Improper use can result in electric shock or fire.

• Älä ylitä kullekin toiminnolle määritettyjä enimmäissyöttöarvoja.
• Ensure test leads are properly connected and in good condition before making measurements.
• Do not use the multimeter if it appears damaged or if the battery cover is not securely closed.
• Ole erittäin varovainen, kun työskentelet voltagyli 60 V DC:n tai 30 V AC:n RMS-jännitteille, koska ne aiheuttavat sähköiskun vaaran.
• Katkaise aina virta testattavasta piiristä ennen resistanssin, kapasitanssin tai jatkuvuuden mittaamista.
• Vaihda paristot viipymättä, kun heikon pariston varoitusvalo tulee näkyviin, jotta mittaustulokset ovat tarkkoja.
• Do not operate the multimeter in explosive atmospheres or near flammable materials.

5. Asennus

5.1. Akun asennus

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

1. Varmista, että yleismittari on sammutettu.
2. Paikanna paristolokero laitteen takana.
3. Avaa paristolokeron kansi ruuvimeisselillä.
4. Aseta 4 AAA-paristoa lokeroon ja huomioi oikea napaisuus (+/-) lokeron sisällä olevien merkkien mukaisesti.
5. Sulje paristolokeron kansi kunnolla.

5.2. Testijohtojen liittäminen

Mittausjohtojen oikea kytkentä on ratkaisevan tärkeää tarkkojen ja turvallisten mittausten kannalta.

• Insert the black test lead into the “COM” (Common) jack.
• Useimmille volyymeilletage, 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. Käyttöohjeet

6.1. Virta päälle/pois

Paina Tehoa button (red circle with line) to turn the multimeter on or off.

6.2. Toiminnon valinta

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

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

6.3. Mittaustilat

Ensure test leads are correctly inserted for the desired measurement.

6.3.1. VoitagMittaus (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 mittaus.
3. Tarvittaessa paina SEL to switch between AC and DC voltage.
4. Kytke mittausjohtimet rinnan mitattavan piirin tai komponentin kanssa.

6.3.2. Virran mittaus (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. Tarvittaessa paina SEL to switch between AC and DC current.
4. Kytke mittausjohdot sarjaan mitattavan virtapiirin kanssa.
