3. البدء: الإعداد

تركيب البطارية

The Fluke 325 requires two AA batteries (included). To install or replace batteries:

1. تأكد من إيقاف تشغيل العداد.
2. حدد مكان حجرة البطارية في الجزء الخلفي من العداد.
3. استخدم مفك براغي لفتح غطاء حجرة البطارية.
4. Insert two AA batteries, observing correct polarity.
5. استبدل غطاء حجرة البطارية وثبته بالمسمار.

ربط خيوط الاختبار

للمجلدtage, resistance, continuity, frequency, temperature, and capacitance measurements, connect the test leads to the appropriate input jacks:

• Insert the black test lead into the COM (common) jack.
• Insert the red test lead into the VΩHz jack for most measurements.

The large yellow rotary dial on the front of the meter is used to select the desired measurement function. Turn the dial to the appropriate setting for your task.

قياس التيار المتردد/المستمر (Clamp)

To measure AC or DC current:

1. Turn the function dial to the ∼A (AC current) or =A (DC current) position.
2. افتح الكلamp jaws by pressing the lever.
3. Place the jaws around a single conductor. Ensure the jaws are fully closed.

المقاومة والاستمرارية

To measure resistance or check continuity:

1. Connect the test leads.
2. Turn the function dial to the Ω (resistance/continuity) position.
3. Touch the test probes across the component or circuit path.
4. For resistance, read the value on the display. For continuity, the meter will beep if a continuous path is detected.

Frequency, Temperature, and Capacitance

The Fluke 325 also offers specialized measurements:

• التردد (هرتز): Select the Hz function to measure the frequency of AC signals.
• درجة الحرارة (°مئوية/°فهرنهايت): Use the included temperature probe and select the temperature function to measure temperature.
• السعة: Select the capacitance function to measure the capacitance of components.

True-RMS Accuracy

The True-RMS feature ensures accurate measurements of AC voltage and current, even when waveforms are distorted or non-sinusoidal. This is crucial for modern electrical systems with non-linear loads.

الخلفية

The Fluke 325 features a backlit display for improved visibility in dimly lit environments. Press the backlight button to activate or deactivate the backlight.

5. الصيانة والعناية

تنظيف

To clean the meter, wipe it with a damp استخدم قطعة قماش ومنظفًا معتدلًا. لا تستخدم مواد كاشطة أو مذيبات. تأكد من جفاف الجهاز تمامًا قبل الاستخدام.

استبدال البطارية

When the battery indicator appears on the display, replace the batteries as described in the 'Battery Installation' section.

تخزين

Store the meter in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.

6. استكشاف المشكلات الشائعة وإصلاحها

• لا يوجد عرض/طاقة: تحقق من تركيب البطارية وتأكد من عدم نفاذ شحنها.
• قراءات غير دقيقة: Verify correct function and range selection. Ensure test leads are properly connected and not damaged. For current measurements, ensure the clamp jaws are fully closed around a single conductor.
• Continuity Beeper Not Working: Check if the function dial is set to continuity and test leads are making good contact.
• 'OL' on Display: This indicates an overload or out-of-range measurement. Select a higher range or ensure the measured value is within the meter's specifications.
