4.1 Akumuliatoriaus įdėjimas

The Meco 2250-HZ Auto Digital Clamp Meter requires batteries for operation. Batteries are not included with the product. To install or replace batteries:

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

A low battery indication will appear on the display when the battery voltage is low, signaling the need for replacement.

5. Naudojimo instrukcijos

5.1 Bendras veikimas

• Turn the function dial to the desired measurement setting.
• Connect test leads to the appropriate input terminals (COM and VΩ) for voltage, resistance, continuity, or diode tests.
• Srovės matavimams naudokite clamp žandikaulis aplink vieną laidininką.
• Paspauskite PASIRINKTI button to toggle between AC/DC modes or other sub-functions if available for the selected range.
• Paspauskite DUOMENŲ LAIKYMAS mygtuką, kad sustabdytumėte dabartinį rodmenį ekrane. Paspauskite dar kartą, kad atleistumėte.

5.2 AC/DC ttage Matavimas

1. Set the function dial to the "VOLTS" position.
2. Connect the black test lead to the COM terminal and the red test lead to the VΩ terminal.
3. Paspauskite PASIRINKTI button to choose between AC or DC voltage measurement. The display will indicate "AC" or "DC".
4. Prijunkite bandymo laidus lygiagrečiai prie bandomosios grandinės arba komponento.
5. Perskaitykite ttage reikšmė LCD ekrane.

5.3 Kintamosios srovės matavimas (Clamp)

1. Set the function dial to the desired AC current range (40A, 400A, or 1000A).
2. Atidarykite klamp žandikaulį paspausdami gaiduką.
3. Į laidą įdėkite tik vieną grandinės laidininką.amp žandikaulis. Įsitikinkite, kad žandikaulis yra visiškai uždarytas.
4. Nuskaitykite kintamosios srovės vertę LCD ekrane.

5.4 Frequency (Hz) Measurement

1. Set the function dial to the "Hz" position.
2. Connect the black test lead to the COM terminal and the red test lead to the VΩ terminal.
3. Connect the test leads in parallel to the circuit where frequency needs to be measured.
4. Read the frequency value in Hertz (Hz) on the LCD display.

5.5 Audible Continuity Check

1. Set the function dial to the continuity/diode symbol (often shared with resistance).
2. Connect the black test lead to the COM terminal and the red test lead to the VΩ terminal.
3. Touch the test probes across the component or circuit to be tested.
4. If continuity exists (low resistance), the meter will emit an audible beep.

5.6 Diodų bandymas

1. Set the function dial to the continuity/diode symbol.
2. Connect the black test lead to the COM terminal and the red test lead to the VΩ terminal.
3. Connect the red test lead to the anode of the diode and the black test lead to the cathode. The display will show the forward voltage lašas.
4. Reverse the test leads. The display should show "OL" (overload) for a good diode.
