1. Įvadas ir saugos informacija
This manual provides essential instructions for the safe and effective operation, maintenance, and troubleshooting of your VOLTCRAFT VC851 Digital Multimeter. Please read this manual thoroughly before using the device and keep it for future reference.
1.1 Bendrieji saugos įspėjimai
Always adhere to the following safety precautions to prevent electric shock, injury, or damage to the meter or equipment under test:
- The VOLTCRAFT VC851 is rated for CAT III 1000 V and CAT IV 600 V. Ensure you understand these categories and their implications for safe measurement.
- Netepkite daugiau nei vardinis tūristage, kaip pažymėta ant skaitiklio, tarp gnybtų arba tarp bet kurio gnybto ir įžeminimo.
- Būkite atsargūs dirbdami su voltagesant didesnei nei 30 V AC RMS, 42 V pikinei vertei arba 60 V DC įtampai. Šios įtampostagtai kelia šoko pavojų.
- Before each use, inspect the test leads for damaged insulation or exposed metal. Replace damaged leads immediately.
- Ensure the rotary switch is in the correct position for the desired measurement before connecting the test leads to the circuit.
- Never use the meter if it appears damaged or if the case is open.
- Nenaudokite matuoklio sprogioje dujų, garų ar dulkių aplinkoje.
- Prieš keisdami funkciją arba diapazoną, visada atjunkite bandymo laidus nuo grandinės.
- Kad rodmenys būtų tikslūs, pakeiskite bateriją, kai tik pasirodys išsikrovusios baterijos indikatorius.

3.2 Bandymo laidų prijungimas
To prepare for measurements:
- Įkiškite juodą bandymo laidą į „COM“ (bendrą) įvesties lizdą.
- Įkiškite raudoną bandymo laidą į atitinkamą matavimo įvesties lizdą:
- "VΩHz" for voltage, resistance, frequency, capacitance, and diode tests.
- "mAµA" for milliampčia ir mikroampsrovės matavimai.
- "10A" for high current (up to 10A) measurements.

4. Naudojimo instrukcijos
The VOLTCRAFT VC851 features a rotary dial for selecting primary measurement functions and buttons for secondary functions and settings.
4.1 Funkcijos pasirinkimas
Turn the central rotary dial to select the desired measurement function (e.g., V for voltage, A for current, Ω for resistance). The meter will automatically select the appropriate range (Auto-Range) for most measurements.
4.2 Matavimo režimai
- ttage (V~ / V-): Matuokite kintamosios arba nuolatinės srovės įtampątage. Select the appropriate voltage range using the rotary dial.
- Current (A~ / A-): Measure AC or DC current. Ensure test leads are connected to the correct current input jacks (mAµA or 10A) and the rotary dial is set to the corresponding current range.
- Varža (Ω): Measure resistance in ohms.
- Tęstinumas: Test for continuity with an audible buzzer.
- Diodo testas: Test diodes for proper function.
- Talpa (F): Measure capacitance in farads.
- Dažnis (Hz): Measure frequency in hertz.
- Temperatūra (°C/°F): Measure temperature using the included temperature probe.
4.3 Ypatingos savybės
- Žibintuvėlis: Press the dedicated flashlight button to illuminate the work area.
- Ekrano apšvietimas: The display features backlighting for improved visibility in low-light conditions.
- Duomenų sulaikymas: Press the "HOLD" button to freeze the current reading on the display.
- Min/Max: Use the "MIN/MAX" function to record the minimum and maximum values during a measurement session.

5. Priežiūra
Proper maintenance ensures the longevity and accuracy of your VOLTCRAFT VC851 Digital Multimeter.
5.1 Valymas
- Always turn off the meter and disconnect test leads before cleaning.
- Nuvalykite dėklą su skelbimuamp audiniu ir švelniu plovikliu. Nenaudokite abrazyvinių ar tirpiklių.
- Ensure no moisture enters the case.
5.2 Akumuliatoriaus keitimas
Refer to Section 3.1 for detailed instructions on battery replacement. Replace batteries promptly when the low battery indicator appears to maintain measurement accuracy.
5.3 Saugiklio keitimas
If the current measurement function stops working, the fuse may need replacement. Fuses are critical safety components. Always replace with a fuse of the specified type and rating.
- Įsitikinkite, kad multimetras yra IŠJUNGTAS, ir atjunkite visus bandymo laidus.
