2. Saugos informacija

Norėdami užtikrinti saugų skaitiklio veikimą ir aptarnavimą, vadovaukitės šiomis instrukcijomis. Nesilaikant šių įspėjimų galima sunkiai susižeisti arba mirtis.

• Prieš keisdami funkcijas, visada atjunkite bandymo laidus nuo grandinės.
• 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 kintamosios srovės RMS įtampai, 42 V pikinei vertei arba 60 V nuolatinės srovės įtampai. Tokia įtampatagtai kelia šoko pavojų.
• Matavimams visada naudokite tinkamus gnybtus, funkciją ir diapazoną.
• Nenaudokite matuoklio, jei jis atrodo pažeistas arba jei korpusas yra atidarytas.
• Kad išvengtumėte neteisingų rodmenų, pakeiskite bateriją, kai tik pasirodys išsikrovusios baterijos indikatorius.
• Nenaudokite matuoklio sprogioje dujų, garų ar dulkių aplinkoje.
• Ensure test leads are in good condition, with no damaged insulation.

4. Naudojimo instrukcijos

4.1 Maitinimo įjungimas/išjungimas

Turn the rotary dial from the OFF position to any measurement function to power on the multimeter. To power off, turn the dial back to the OFF position. The multimeter also features an automatic power-off function to conserve battery life.

4.2 Funkcijos pasirinkimas

Rotate the central dial to select the desired measurement function (e.g., V~ for AC Voltage, V – nuolatinės srovės įtampaitage, Ω for Resistance, A~ for AC Current, A- for DC Current, Temp for Temperature, etc.).

4.3 Mygtukų funkcijos

• DIAPAZONAS: Switches between automatic and manual ranging. In manual range, press repeatedly to cycle through available ranges.
• LAIKYTI/☀: Press once to hold the current reading on the display. Press again to release. Long press to activate/deactivate the backlight.
• REL△: Relative measurement mode. Displays the difference between the current reading and a stored reference value.
• MAX/MIN: Records and displays the maximum and minimum values measured during a session.
• Hz %: For frequency and duty cycle measurements.
• SEL/NCV: Selects between different sub-functions within a dial position (e.g., AC/DC, Diode/Continuity). Long press to activate Non-Contact Voltage (NCV) aptikimas.

4.4 Matavimų atlikimas

Always ensure the test leads are connected to the correct jacks and the function dial is set to the appropriate measurement type before connecting to a circuit.

1. ttagMatavimas (kintamoji/nuolatinė): Select V~ for AC or V- for DC. Connect test leads in parallel with the circuit or component.
2. Srovės matavimas (AC/DC): Select A~ for AC or A- for DC. Connect test leads in series with the circuit. Ensure the correct current jack (mAµA or 10A) is used.
3. Varžos matavimas (Ω): Select Ω. Connect test leads across the component when it is de-energized.
4. Talpos matavimas: Select the capacitance function. Connect test leads across the capacitor when it is de-energized.
5. Diodo testas: Select the diode function. Connect test leads across the diode.
6. Tęstinumo testas: Select the continuity function. Connect test leads across the circuit. A beep indicates continuity.
7. Dažnis (Hz) / Darbo ciklas (%): Select the Hz% function. Connect test leads to the signal source.
8. Temperatūros matavimas: Connect the temperature probe to the appropriate jacks (usually VΩHz and COM). Select the temperature function.
9. Nekontaktinis ttage (NCV): Long press the SEL/NCV button. Bring the top of the multimeter near an AC voltage source. The meter will indicate the presence of voltage be tiesioginio kontakto.
