د بیټرۍ تنظیم او نصب کول
The multimeter requires one 9V battery for operation. Ensure the battery is correctly installed before first use.
- د ملټي میټر شاته د بیټرۍ کڅوړه ومومئ.
- د بیټرۍ کمپارټ پوښ خلاص کړئ.
- یو نوی 9V بیټرۍ دننه کړئ، سم قطبي حالت (+/-) وګورئ.
- د بیټرۍ کمپارټ پوښ په خوندي ډول وتړئ.
Connect the included test leads to the appropriate jacks on the multimeter. The red lead typically connects to the positive (+) or VΩmA jack, and the black lead connects to the common (COM) jack.
عملیاتي لارښوونې
To operate the multimeter, turn the rotary switch to the desired function and range. The digital display will show the measurement. Always select a range higher than the expected measurement to avoid damaging the device.
د اندازه کولو دندې:
- DC Voltagای (ډي سي وي): Used for measuring direct current voltage. Select the appropriate DCV range (e.g., 200mV, 2V, 20V, 200V, 250V).
- AC Voltage (ACV): Used for measuring alternating current voltage. Select the appropriate ACV range (e.g., 200V, 250V).
- د ډي سي جریان (DCA): Used for measuring direct current. Select the appropriate DCA range (e.g., 200µA, 2mA, 20mA, 200mA, 5A).
- مقاومت (Ω): Used for measuring electrical resistance in ohms. Select the appropriate Ohm range (e.g., 200Ω, 2KΩ, 20KΩ, 200KΩ, 2000KΩ).
- د ډایډ ټیسټ: Used to check the functionality of diodes.
- Transistor (hFE) Test: Used to measure the DC current gain of transistors.
For detailed instructions on specific measurement procedures, refer to specialized electrical guides or instructional videos. Always ensure proper safety precautions are followed when working with electricity.
ساتنه
د خپل ملټي میټر د اوږدوالي او دقت ډاډمن کولو لپاره، د ساتنې دا لارښوونې تعقیب کړئ:
- ملټي میټر پاک او وچ وساتئ. د نرم، ډ سره مسح کړئamp ټوکر؛ د کثافاتو پاکوونکي یا محلول مه کاروئ.
- Replace the 9V battery when the low battery indicator appears on the display to ensure accurate readings.
- The circuit is fuse and diode protected. If the multimeter stops functioning correctly, check the internal fuse (refer to a qualified technician for fuse replacement if necessary).
- ملټي میټر په یخ او وچ ځای کې د مستقیم لمر وړانګو او سختې تودوخې څخه لرې وساتئ.
د ستونزو حل کول
If you encounter issues with your multimeter, consider the following common solutions:
- هیڅ ښودنه یا تیاره ښودنه نشته: د 9V بیټرۍ وګورئ او بدله یې کړئ.
- "OL" or Overrange Indicator: The measured value exceeds the selected range. Switch to a higher range setting.
- ناسم لوستل: Ensure test leads are properly connected, the correct function and range are selected, and the battery is not low.
- No continuity/resistance reading: Check if the test leads are damaged or if the internal fuse has blown.
For persistent issues or complex repairs, it is recommended to consult a qualified electrician or technician.
