2. Saugos informacija

WARNING: To avoid electrical shock or personal injury, read and understand all instructions before using this meter. Always operate with the battery cover securely closed.

• Prieš naudodami visada patikrinkite, ar matuoklis ir bandymo laidai nėra pažeisti. Nenaudokite, jei pažeisti.
• 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.
• Visada atjunkite grandinės maitinimą ir iškraukite visus didelės įtampos krūvius.tage kondensatoriai prieš išbandydami varžą, tęstinumą, diodus ar talpą.
• Nenaudokite matuoklio šalia sprogių dujų, garų ar dulkių.
• Ensure the rotary switch is in the correct position for the desired measurement before connecting the test leads to the circuit.
• When making current measurements, ensure the circuit is de-energized before clamping the meter around the conductor.

5.1 Akumuliatoriaus įdėjimas

1. Įsitikinkite, kad skaitiklis yra IŠJUNGTAS.
2. Raskite baterijų skyrių matuoklio gale.
3. Baterijų skyriaus dangteliui atidaryti naudokite atsuktuvą.
4. Insert three (3) 1.5V AAA batteries, observing the correct polarity (+/-).
5. Uždėkite akumuliatoriaus skyriaus dangtelį ir pritvirtinkite jį varžtu.

Note: The meter will display a low battery indicator when the batteries need replacement.

6. Naudojimo instrukcijos

The MS2138 features a rotary switch to select measurement functions and buttons for additional controls.

6.1 Pagrindinės operacijos

• Maitinimo įjungimas/išjungimas: Rotate the central dial from 'OFF' to any desired function to power on. Rotate back to 'OFF' to power off. The meter features auto power off to conserve battery life.
• Funkcijų pasirinkimas: Use the rotary switch to select the primary measurement type (e.g., V~ for AC Voltage, A~ for AC Current).
• 'FUNC' Button: Press this button to cycle through sub-functions within a rotary switch position (e.g., AC/DC voltage, resistance/continuity/diode/capacitance).
• 'RANGE' Button: Toggles between auto-ranging and manual ranging. In manual ranging, press repeatedly to select desired range.
• 'REL' Button (Relative Measurement): Stores the current reading as a reference value. Subsequent measurements will display the difference from this reference.
• 'Hz/%' Button (Frequency/Duty Cycle): Used to measure frequency or duty cycle in relevant modes.
• 'HOLD' Button: Įšaldo dabartinį rodmenį ekrane. Paspauskite dar kartą, kad atleistumėte.
• 'MAX/MIN' Button: Records the maximum and minimum values during a measurement session. Press and hold for 2 seconds to activate.
• Backlight/Work Light: The meter features a display backlight for low-light conditions and a work light near the clamp žandikaulis.

6.2 Measuring AC/DC Current (Clamp Funkcija)

1. Rotate the dial to the 'A~' (AC Current) or 'A=' (DC Current) position.
2. Atidarykite klamp žandikaulį paspausdami gaiduką.
3. Padėkite klamp around a single conductor (not a cable containing multiple conductors) of the circuit you wish to measure.
4. Ensure the jaw is fully closed.
5. Nuskaitykite dabartinę vertę ekrane.

Example of using the clamp meter to measure frequency from an electrical outlet.

6.3 AC/DC matavimas Voltage

1. Insert the red test lead into the 'VΩHz' input terminal and the black test lead into the 'COM' terminal.
2. Rotate the dial to the 'V~' (AC Voltage) arba „V=“ (nuolatinės srovės tūriotage) padėtis.
3. Prijunkite bandymo laidus prie matuojamos grandinės arba komponento.
4. Perskaitykite ttage reikšmė ekrane.

6.4 Measuring Resistance, Continuity, Diode, and Capacitance

1. Insert the red test lead into the 'VΩHz' input terminal and the black test lead into the 'COM' terminal.
2. Rotate the dial to the 'Ω' (Resistance/Continuity/Diode/Capacitance) position.
3. Press the 'FUNC' button to cycle through Resistance (Ω), Continuity (Buzzer icon), Diode (Diode icon), and Capacitance (F).
4. Connect the test leads to the component. For resistance and capacitance, ensure the component is de-energized.
5. Read the measurement on the display. For continuity, the buzzer will sound if resistance is below 50±20Ω.

8. Priežiūra

8.1 Valymas

Nuvalykite skaitiklį reklamaamp šluoste ir švelniu plovikliu. Nenaudokite abrazyvinių medžiagų ar tirpiklių. Saugokite įvesties gnybtus nuo purvo ir drėgmės.

8.2 Akumuliatoriaus keitimas

When the low battery indicator appears on the display, replace the batteries as described in the 'Battery Installation' section (5.1). Always use three new 1.5V AAA batteries.

8.3 Saugykla

If the meter is not to be used for an extended period, remove the batteries to prevent leakage and damage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.

Jokių konkrečių naudotojų patarimų iš re nebuvo pateikta.views or Q&A for this product at this time. However, general tips for clamp meter users include:

• Visada užtikrinkite, kad clamp jaw is fully closed for accurate current measurements.
• When measuring current, clamp around only one conductor. Clamping around a multi-conductor cable will result in a zero reading as the magnetic fields cancel each other out.
• For stable readings, especially in noisy electrical environments, use the 'HOLD' function to capture a momentary value.
• The 'REL' function is useful for nulling out test lead resistance when measuring small resistances or for comparing measurements against a known baseline.
