2. Saugos informacija

ĮSPĖJIMAS: Kad išvengtumėte galimo elektros smūgio, gaisro ar sužalojimo, prieš naudodami gaminį, perskaitykite visą saugos informaciją.

• Prieš atlikdami matavimus, visada įsitikinkite, kad multimetras yra tinkamoje funkcijoje ir diapazone.
• 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. Šie įtampų lygiaitagtai kelia šoko pavojų.
• Before measuring current, ensure the circuit is de-energized and the meter is connected in series with the load.
• Never measure resistance, continuity, or diode on a live circuit.
• Prieš naudodami patikrinkite bandymo laidus, ar nėra pažeistos izoliacijos arba atviro metalo. Jei pažeista, pakeiskite.
• Nenaudokite skaitiklio, jei jis atrodo pažeistas arba jei korpusas yra atidarytas.
• Remove test leads from the meter before opening the battery cover or fuse cover.
• Kad rodmenys būtų tikslūs, pakeiskite bateriją, kai tik pasirodys išsikrovusios baterijos indikatorius.
• Laikykitės vietinių ir nacionalinių saugos taisyklių.

4.1 Akumuliatoriaus įdėjimas

The ANENG V7 Multimeter typically uses standard batteries (e.g., AA or 9V, check the battery compartment for specifics). To install or replace batteries:

1. Įsitikinkite, kad multimetras yra IŠJUNGTAS, ir atjunkite visus bandymo laidus nuo įvesties gnybtų.
2. Įrenginio gale suraskite baterijų skyriaus dangtelį.
3. Atsuktuvu atidarykite akumuliatoriaus skyrių.
4. Insert new batteries, observing the correct polarity (+ and -).
5. Uždėkite akumuliatoriaus skyriaus dangtelį ir pritvirtinkite jį varžtu.

4.2 Bandymo laidų prijungimas

Always connect the black test lead to the "COM" (common) jack. Connect the red test lead to the appropriate input jack based on the measurement you intend to make:

• Dėl ttage, Resistance, Capacitance, Frequency, Diode, Continuity, and Temperature measurements: Connect the red lead to the "VΩHz-II+" jack.
• For Current (mA/µA) measurements: Connect the red lead to the "mAµA" jack.
• For High Current (A) measurements: Connect the red lead to the "20A" jack.

5. Naudojimo instrukcijos

The ANENG V7 features both auto-ranging and manual mode capabilities. The intelligent recognition function simplifies operation for common measurements.

Figure 5.1: The intelligent anti-burn feature with smart recognition helps prevent damage from incorrect settings, especially when the rotary dial is set to 'AUTO'.

5.1 Pagrindiniai matavimo žingsniai

1. Turn the rotary dial to the desired function (e.g., V~ for AC Voltage, V – nuolatinės srovės įtampaitage, Ω for Resistance, etc.). For most common measurements, the "AUTO" setting will automatically detect the type of measurement.
2. Connect the test leads to the circuit or component you wish to measure, ensuring correct polarity and connection points.
3. Nuskaitykite matavimo vertę LCD ekrane.
4. After measurement, disconnect the test leads from the circuit, then from the multimeter.
5. Turn the rotary dial to "OFF" when not in use to conserve battery life.

5.2 Specifinės matavimo funkcijos

• DC/AC ttage Measurement (V-, V~):

  Set the rotary dial to V- (DC) or V~ (AC) or AUTO. Connect test leads in parallel to the circuit. The meter will display the voltage vertė.

• DC/AC Current Measurement (A, mA, µA):

  Set the rotary dial to the appropriate current range (A, mA, or µA). Connect the meter in series with the circuit. Ensure the circuit is de-energized before connecting the meter.

• Varžos matavimas (Ω):

  Set the rotary dial to Ω or AUTO. Ensure the circuit is de-energized. Connect test leads across the component. The meter will display the resistance value.
• Capacitance Measurement (F):

  Set the rotary dial to F or AUTO. Ensure the capacitor is discharged before measurement. Connect test leads across the capacitor terminals.

• Dažnio matavimas (Hz):

  Set the rotary dial to Hz or AUTO. Connect test leads to the signal source. The meter will display the frequency.

• Diodo testas (→|):

  Set the rotary dial to the diode symbol. Connect the red lead to the anode and the black lead to the cathode. The meter displays the forward voltage lašas.
• Tęstinumo testas ()))):

  Set the rotary dial to the continuity symbol. Connect test leads across the circuit or component. A built-in buzzer will sound if the resistance is below a certain threshold (typically <50Ω).

• Temperatūros matavimas (°C/°F):

  Set the rotary dial to TEMP. Connect the temperature probe (thermocouple) to the input jacks. Place the probe on the object to be measured.

• No Display / Power On Issue:

  Check battery installation and ensure batteries are not depleted. Replace if necessary. Ensure the rotary dial is not in the "OFF" position.

• Neteisingi skaitymai:

  Verify the correct function and range are selected. Check test lead connections. Ensure batteries are not low. Calibrate if necessary (advanced users only).

• Current Measurement Not Working:

  Check if the fuse for the current input is blown. Replace if necessary (refer to Section 6.3).
• Continuity Buzzer Not Sounding:
