1. المقدمة

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. معلومات السلامة

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. الإعداد

4.1 تركيب البطارية

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

1. حدد مكان غطاء حجرة البطارية على الجزء الخلفي للجهاز.
2. Use a suitable tool (e.g., a small screwdriver) to open the cover.
3. قم بإدخال البطاريات الثلاث AAA، مع التأكد من القطبية الصحيحة (+/-).
4. أغلق غطاء حجرة البطارية بإحكام.

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.

5.1 المجلدtagالقياس (التيار المتردد/المستمر)

لقياس الحجمtage:

1. Connect both test probes to the circuit or component you wish to measure.
2. المجلدtage 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. يكتشف الجهاز تلقائيًا جهد التيار المتردد أو التيار المستمرtage.

5.2 اختبار الاستمرارية

لإجراء اختبار الاستمرارية:

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. الصيانة

• تنظيف: Clean the device regularly with a dry, lint-free cloth. Do not use abrasive cleaners or solvents.
• تخزين: 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.
• استبدال البطارية: Replace batteries when the low battery indicator appears on the LCD.

7. استكشاف الأخطاء وإصلاحها

• لا يوجد عرض/لا يوجد طاقة: تحقق من تركيب البطارية وتأكد من عدم نفاذ شحنها. استبدلها إذا لزم الأمر.
• قراءات غير دقيقة: Ensure probes are making good contact with the test points. Verify the tester on a known voltagالمصدر هـ.
• No Continuity Indication: Ensure the circuit is de-energized. Check for open circuits or high resistance.
• Tester Not Responding: Remove batteries, wait a few seconds, and reinsert them. If the issue persists, contact customer support.
