VOLTCRAFT VC-55 LCD 2-Pole Voltage Manual Arahan Penguji

1. Pengenalan

This manual provides essential information for the safe and effective use of your VOLTCRAFT VC-55 LCD 2-Pole Voltage Tester. This device is designed for reliable voltage testing, continuity checks, unipolar phase testing, and rotating field testing. It features both an LCD and LED display for clear readings and is built to meet EN 61243-3 and VDE0682 standards, ensuring high safety and performance.

2. Maklumat Keselamatan

WARNING: Electrical testing can be hazardous. Always follow safety precautions to prevent injury or damage.

• Always inspect the tester for damage before use. Do not use if the housing, test leads, or probes are damaged.
• Ensure the device is rated for the voltage and current levels you intend to measure. This tester is rated CAT III 1000 V and CAT IV 600 V.
• Never touch live conductors with bare hands. Use appropriate personal protective equipment (PPE).
• Do not use the tester in wet conditions or in explosive atmospheres.
• Verify the tester's functionality on a known live source before and after each use.
• If you are unsure about any procedure, consult a qualified electrician.

4. Persediaan

4.1 Pemasangan Bateri

The VC-55 LCD requires 2 AAA batteries (included) for operation. To install or replace batteries:

1. Cari penutup petak bateri di bahagian belakang peranti.
2. Use a suitable tool (e.g., a small screwdriver) to open the cover.
3. Masukkan 2 bateri AAA, pastikan kekutuban (+/-) yang betul.
4. Tutup penutup petak bateri dengan selamat.

4.2 Probe Preparation

The test probes come with protective caps and interchangeable tips. For most applications, the standard tips are suitable. For testing in sockets with child protection, screw-on round tips are provided.

5. Arahan Operasi

5.1 Jldtage Pengukuran (AC/DC)

Untuk mengukur voltage:

1. Connect both test probes to the circuit or component you wish to measure.
2. Jilidtage value will be displayed on the LCD screen.
3. Corresponding LEDs will illuminate to indicate the voltage range (12V, 24V, 50V, 120V, 230V, 400V, 690V).
4. The device automatically detects AC or DC voltage.

5.2 Ujian Kesinambungan

Untuk melakukan ujian kesinambungan:

1. Ensure the circuit is de-energized before testing for continuity.
2. Touch the two test probes to the ends of the circuit or component you want to test.
3. If continuity exists (low resistance), an acoustic signal will sound, and a dedicated LED will illuminate.

5.3 Unipolar Phase Test

To test for phase (live wire) in AC circuits:

1. Hold the main body of the tester firmly.
2. Touch only one test probe to the conductor you suspect is live.
3. If the conductor is live, the phase indicator (usually an 'R' or similar symbol) on the display will light up.

5.4 Rotating Field Test

To determine the phase sequence in three-phase systems:

1. Connect the test probes to two phases of the three-phase system.
2. The tester will indicate the direction of the rotating field (e.g., 'L' for left, 'R' for right, or arrows).

6. Penyelenggaraan

• Pembersihan: Clean the device regularly with a dry, lint-free cloth. Do not use abrasive cleaners or solvents.
• Storan: Store the tester in a dry, cool place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
• Penggantian Bateri: Gantikan bateri apabila penunjuk bateri rendah muncul pada LCD.

7. Penyelesaian masalah

• Tiada Paparan/Tiada Kuasa: Periksa pemasangan bateri dan pastikan bateri tidak habis. Gantikan jika perlu.
• Bacaan Tidak Tepat: Ensure probes are making good contact with the test points. Verify the tester on a known voltage sumber.
• Tiada Petunjuk Kesinambungan: Pastikan litar dinyahtenagakan. Semak litar terbuka atau rintangan tinggi.
• Tester Not Responding: Remove batteries, wait a few seconds, and reinsert them. If the issue persists, contact customer support.
