5. الإعداد

5.1 تركيب البطارية

The ETCR2100A+ requires four (4) 1.5V AA batteries (not included).

1. حدد موقع غطاء حجرة البطارية في الجزء الخلفي من الجهاز.
2. Use a suitable tool (if necessary) to open the battery compartment.
3. Insert four 1.5V AA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. أغلق غطاء حجرة البطارية جيدًا.

5.2 التشغيل المبدئي

بعد تركيب البطارية، اضغط على تشغيل/إيقاف button to power on the device. The LCD display will illuminate, indicating the device is ready for use.

6. تعليمات التشغيل

6.1 القياس الأساسي

To perform a grounding resistance test:

1. تأكد من تشغيل الجهاز.
2. افتح الكلamp فكّي الفكين بالضغط على الزناد.
3. ضع الكلamp around the grounding conductor or circuit to be measured. Ensure the jaws are fully closed around the conductor.
4. The resistance value will be displayed on the LCD screen. The device features fully automatic shifting.
5. The single measurement time is approximately 0.5 seconds.

6.2 Single Point Grounding System, Auxiliary Measurement

For single point grounding systems where direct clamp measurement of the lead wire is not feasible, auxiliary methods can be used. The two-point method is illustrated below:

Image 6.2: Diagram showing the two-point method for auxiliary grounding resistance measurement. It depicts a grounding rod (RA) connected to a single point, with a wire extending to a natural grounding point (e.g., water pipe, buried metal) for measurement.

لاستخدام هذه الطريقة:

• Identify a natural grounding point with a low resistance value near the grounding point to be measured. Examples include a water pipe, fire hydrant, or other deeply buried metal structure.
• Connect a wire from the point to be measured to this auxiliary grounding point.
• Clamp the ETCR2100A+ around the connecting wire to perform the measurement.

6.3 تخزين البيانات واسترجاعها

يمكن للجهاز تخزين ما يصل إلى 99 مجموعة من بيانات القياس.

• To store data: After a measurement, press the ميم button to save the current reading.
• To retrieve data: Press the ميم button repeatedly to cycle through stored data.

6.4 وظيفة الإنذار

The ETCR2100A+ features an audible and visual alarm for out-of-range measurements.

• To activate/deactivate the alarm: Press the AL زر.
• To set alarm thresholds: Refer to the device's on-screen menu or specific instructions for setting resistance (1-199 Ω) and current (1-499mA) alarm limits.
