4. الإعداد والتثبيت

The DVM230W module is designed for recessed mounting. Ensure the mounting surface has an opening of 45 x 22 mm.

1. التركيب: Carefully insert the module into the prepared opening. The module is designed to snap into place. Ensure a snug fit to prevent movement. If the fit is too tight, minor adjustments to the opening or the use of a small amount of adhesive may be necessary.
2. التوصيلات الكهربائية: Connect the module to the male bars of your system. Refer to the wiring diagram provided with your specific application for correct polarity and signal connections.
3. Extending Measurement Range (Optional): لقياس الحجمtages or currents beyond the module's default range (e.g., 0-200 mV), external resistors (voltage splitter for voltage, shunt for current) must be connected in series.
4. Internal Configuration for Extended Range: If extending the measurement range, it is crucial to remove the 0 Ohm SMD resistor at position RA on the circuit board. Failure to do so before installing a voltage divider or shunt can damage the device. Consult the detailed circuit diagram for precise location of RA.
5. Unit and Decimal Adjustment: The module allows for adjustment of displayed units and decimal places. This is typically done via solder bridges or pin headers on the circuit board. Refer to the detailed internal diagram for specific configuration points.

5. تعليمات التشغيل

Once installed and powered, the DVM230W module will display the measured value on its digital screen.

• قراءة العرض: The 10 mm digits provide clear readings. The white backlight ensures visibility in various lighting conditions.
• إشارة الوحدة: The display will show the configured unit (e.g., V, mV, A, mA, Ohms, kOhms, MOhms, °C, °F) alongside the numerical value.
• Data-Hold Function: If equipped with a data-hold feature (check your specific model's pinout/buttons), activate it to freeze the current reading on the display.
• Battery Wear Indicator: The module includes a battery wear indicator. If this indicator activates, it suggests the internal power source (if applicable) or the external power supply is insufficient or failing.

6. الصيانة

The VOLTCRAFT DVM230W module requires minimal maintenance.

• تنظيف: استخدم قطعة قماش ناعمة وجافة لتنظيف الشاشة وasing. Do not use abrasive cleaners or solvents, as these can damage the plastic and display.
• تقتيش: Periodically inspect the connections for any signs of corrosion or loose wiring.
• الظروف البيئية: Ensure the module operates within its specified temperature and humidity ranges to prolong its lifespan.

7. استكشاف الأخطاء وإصلاحها

• No Display/Incorrect Reading:
  • تحقق من توصيلات مصدر الطاقة وتأكد من صحة الجهدtage.
  • Verify input signal connections for correct polarity and range.
  • If using an extended measurement range, confirm that the 0 Ohm SMD resistor at RA was correctly removed before installing external resistors. Incorrect configuration here can lead to erroneous readings or damage.
• عرض الخفقان:
  • تحقق من عدم استقرار مصدر الطاقة.
  • Ensure proper grounding to minimize electrical interference.
• Battery Wear Indicator Active:
  • If the module uses an internal battery, replace it.
  • If powered externally, check the stability and voltage of the external power source.
