LARIAU TS58 Digital Insulation Resistance Tester

1. المقدمة

The LARIAU TS58 is a digital insulation resistance tester designed for measuring insulation resistance in various electrical equipment and insulating materials. This includes transformers, motors, cables, switches, and other electrical appliances. It is suitable for maintenance, repair, and testing applications.

This instrument features automatic voltage release, high stability, and reliability. It offers a maximum display count of 2000, 100 groups of data storage, and an insulation resistance measurement range of 0.1 MΩ to 10 GΩ. It also includes AC/DC voltage measurement capabilities and advanced DAR (Dielectric Absorption Ratio) and PI (Polarization Index) measurements for more accurate insulation assessment.

4. الإعداد

4.1 تركيب البطارية

The TS58 is powered by 8 x 1.5V AA/LR6 batteries (not supplied). To install or replace batteries:

1. حدد موقع حجرة البطارية في الجزء الخلفي من الجهاز.
2. افتح غطاء حجرة البطارية.
3. Insert 8 AA/LR6 batteries, ensuring correct polarity (+/-).
4. أغلق غطاء حجرة البطارية جيدًا.

A low battery indication will appear on the display when batteries need replacement.

5. تعليمات التشغيل

The TS58 is designed for measuring insulation resistance and AC/DC voltage. Always ensure the test leads are securely connected to the instrument and the circuit under test.

5.1 قياس مقاومة العزل

1. Connect the test leads to the appropriate terminals on the TS58 and to the equipment under test.
2. قم بتشغيل الصك.
3. Use the 'SELECT' button to choose the insulation resistance measurement mode.
4. ضبط حجم الإخراجtage (50V/100V/250V/500V/1000V) using the up/down buttons as required for your test.
5. Press the 'TEST' button to initiate the measurement. The high voltagسيضيء المؤشر الإلكتروني.
6. Read the insulation resistance value on the LCD screen.
7. After the test, the instrument automatically discharges the circuit.

2. قم بتشغيل الصك.
3. Use the 'SELECT' button to choose the AC or DC voltagوضع القياس ه.
4. اقرأ المجلدtage value on the LCD screen. The measurement range is 10V-600V.

5.3 DAR and PI Index Measurement

The DAR (Dielectric Absorption Ratio) and PI (Polarization Index) measurements help assess the quality and aging status of insulation, mitigating the effects of temperature, humidity, and interference currents.

1. Perform an insulation resistance test as described in section 5.1.
2. Press the 'PI/DAR' button. The instrument will automatically compute and display the DAR and PI values.
3. Refer to industry standards for interpreting DAR and PI values to evaluate insulation condition.

5.4 تخزين البيانات واسترجاعها

The TS58 can store up to 100 groups of measurement data.

• To save data: After a measurement, press the 'HOLD*' button to hold the current reading, then press 'MEM READ' to save it. (Note: The exact sequence might vary; refer to the full manual for precise steps if available).
• To recall data: Press the 'MEM READ' button and use the up/down arrows to navigate through stored data groups.

6. الصيانة

6.1 التنظيف

Wipe the instrument's exterior with a soft, damp قطعة قماش. لا تستخدم منظفات كاشطة أو مذيبات. تأكد من عدم دخول أي رطوبة إلى الجهاز.

6.2 التخزين

When not in use for extended periods, remove the batteries to prevent leakage. Store the instrument in its zipper carry bag in a dry environment, away from direct sunlight and extreme temperatures. The recommended storage environment is -10~50℃, <75%RH.

7. استكشاف الأخطاء وإصلاحها

• الجهاز لا يعمل: تحقق من تركيب البطارية وتأكد من عدم نفاذ شحنها. استبدلها إذا لزم الأمر.
• قراءات غير دقيقة:
  • تأكد من توصيل أسلاك الاختبار بشكل صحيح وعدم تلفها.
  • Verify the correct measurement mode and output voltage are selected.
  • Consider environmental factors like temperature and humidity, especially for insulation resistance measurements.
• حجم كبيرtage warning persists after test: The instrument has an automatic voltage release function. If the warning persists, ensure the circuit under test is fully discharged before handling.
