4. الإعداد

4.1 تركيب البطارية

1. تأكد من إيقاف تشغيل العداد.
2. حدد مكان حجرة البطارية في الجزء الخلفي من العداد.
3. Remove the screw(s) securing the battery cover and lift the cover off.
4. Connect a new 9-volt battery to the battery clips, observing correct polarity.
5. ضع البطارية في الحجرة وأعد الغطاء، وثبته بالبرغي (البراغي).

4.2 توصيل أسلاك الاختبار

• بالنسبة لمعظم المجلداتtage, resistance, and temperature measurements, insert the black test lead into the كوم (common) jack and the red test lead into the فولتا هرتز جاك.
• لإجراء قياسات التيار حتى 400 مللي أمبير، أدخل سلك الاختبار الأحمر في mA جاك.
• For high current measurements up to 20A, insert the red test lead into the 20 أمبير جاك.
• تأكد من أن جميع التوصيلات ثابتة وآمنة.

5. تعليمات التشغيل

5.1 التشغيل العام

• تشغيل/إيقاف التشغيل: Rotate the function switch from OFF to any desired measurement function to turn the meter on. Rotate back to OFF to power off. The meter also features an Auto Power Off function to conserve battery life.
• النطاق التلقائي: The ESI 590 Pro is an auto-ranging DMM, meaning it automatically selects the appropriate measurement range. This simplifies operation, but some measurements may take a moment to stabilize.
• الإضاءة الخلفية: Press the backlight button (often integrated with the HOLD button or a separate button) to illuminate the display for better visibility in low-light conditions.
• امسك المعلومات: اضغط على يمسك button to freeze the current reading on the display. Press it again to release.
• Relative Change Function (REL): اضغط على ريل button to store the current reading as a reference value. Subsequent readings will be displayed as the difference from this reference. Press again to exit relative mode.

5.2 وظائف القياس

Select the desired function by rotating the central switch.

• المجلدtage (V DC/AC): Connect leads as described in Section 4.2. Select the V DC or V AC position on the rotary switch. The meter will auto-range.
• Current (A DC/AC, mA DC/AC): Connect leads to the appropriate current jacks (mA or 20A) and select the corresponding current function on the rotary switch. Ensure the meter is connected in series with the circuit.
• المقاومة (Ω): Connect leads to COM and VΩHz. Select the Ω function. Ensure the circuit is de-energized before measuring resistance.
• Capacitance (CAP): Connect leads to COM and VΩHz. Select the CAP function. Discharge capacitors before testing.
• التردد (هرتز) / دورة التشغيل (%): Connect leads to COM and VΩHz. Select the Hz/% function.
• درجة الحرارة (°مئوية/°فهرنهايت): Connect the temperature probe to the appropriate jacks (usually COM and VΩHz, or dedicated temperature jacks if present). Select the °C or °F function.
• دورة في الدقيقة (الثورات في الدقيقة): Use the inductive RPM pick-up. Connect it to the designated RPM input. Select the RPM function. The inductive pick-up features a five-position adjustable sensitivity switch for optimal signal detection.
• Ms Pulse Width: This function is specifically designed to measure the on-time of fuel injectors. Connect the meter according to the specific instructions for pulse width measurement (refer to advanced automotive diagnostics guides if needed). Select the Ms-PULSE function.
• يسكن: Select the DWELL function to measure the dwell angle in ignition systems.

6. الصيانة

6.1 التنظيف

امسح غلاف العداد بالإعلانamp cloth and a mild detergent. Do not use abrasives or solvents. Keep the display clean and free from scratches.

6.2 استبدال البطارية

When the low battery indicator appears on the display, replace the 9-volt battery as described in Section 4.1. Prompt battery replacement ensures continued accuracy and proper operation.

6.3 استبدال الصمامات

The ESI 590 Pro DMM is protected by internal fuses for current measurement ranges. If the meter fails to read current, the fuse may be blown. Refer to the meter's internal markings for fuse specifications (e.g., 20A fused, 400mA fused) and replace with fuses of identical type and rating. Fuse replacement typically involves opening the meter's back casing, similar to battery replacement, but may require additional steps. Consult a qualified technician if unsure.

6.4 التخزين

When not in use for extended periods, store the meter in its carrying case in a cool, dry environment. Remove the battery if storing for several months to prevent leakage.

7. استكشاف الأخطاء وإصلاحها

• لا يعمل العداد: تحقق من تركيب البطارية وتأكد من شحنها بشكل كافٍ. استبدلها إذا لزم الأمر.
• Inaccurate or unstable readings:
  • Ensure test leads are properly connected and making good contact.
  • تأكد من تحديد الوظيفة والنطاق الصحيحين.
  • Check for external electrical interference.
  • Allow the auto-ranging function sufficient time to stabilize, especially for initial readings.
• Display shows 'OL' (Overload): This indicates the measured value exceeds the selected range. For auto-ranging meters, it means the value is beyond the meter's maximum capability for that function. Ensure the meter is connected correctly and the value is within the meter's specifications.
• No current reading: Check the fuses as described in Section 6.3. Ensure the test leads are connected to the correct current input jacks (mA or 20A) and the meter is in series with the circuit.
• Tachometer not working correctly: Ensure the inductive RPM pick-up is properly connected and positioned. Adjust the five-position sensitivity switch on the pick-up to optimize signal detection. Verify the engine is running and producing a consistent signal.
