4.1 د بیټرۍ نصب کول

The multimeter requires a 9V battery (included). To install or replace the battery:

1. د میټر په شا کې د بیټرۍ کڅوړه ومومئ.
2. Use the included screwdriver to remove the screw securing the battery cover.
3. Insert the 9V battery, observing correct polarity.
4. د بیټرۍ پوښ بدل کړئ او د سکرو سره یې خوندي کړئ.

۶.۲ د ټیسټ لیډونو نښلول

Connect the red and black test leads to the appropriate input jacks on the multimeter. The black lead typically connects to the 'COM' (common) jack, and the red lead connects to the jack corresponding to the desired measurement function (e.g., VΩmA for voltage, resistance, or small current measurements).

5. عملیاتي لارښوونې

۸ پاور آن/بند

فشار ورکړئ پاور button to turn the multimeter on. To turn it off, press the پاور button again or wait for the auto-off function to activate.

5.2 Capacitance Measurement (C)

The GC-4070L can measure capacitance from 2000pF to 200µF.

1. Rotate the function switch to the desired 'C' (Capacitance) range (e.g., 2000pF, 20nF, 200nF, 2µF, 20µF, 200µF).
2. مهم: Before measuring, ensure the capacitor is fully discharged to avoid damage to the meter.
3. Connect the test leads to the capacitor terminals. The reading will appear on the LCD display.

5.3 Inductance Measurement (L)

The GC-4070L can measure inductance from 20mH to 20H.

1. Rotate the function switch to the desired 'L' (Inductance) range (e.g., 20mH, 200mH, 2H, 20H).
2. Connect the test leads to the inductor terminals. The reading will appear on the LCD display.

۵.۲ د مقاومت اندازه کول (Ω)

The GC-4070L can measure resistance from 20Ω to 2000MΩ.

1. Rotate the function switch to the desired 'Ω' (Resistance) range (e.g., 20Ω, 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ, 20MΩ, 200MΩ, 2000MΩ).
2. Connect the test leads to the resistor terminals. The reading will appear on the LCD display.

5.5 hFE Test

The hFE test function allows for testing of transistor gain.

1. Rotate the function switch to the 'hFE' position.
2. Insert the transistor leads into the appropriate sockets on the meter (E, B, C for Emitter, Base, Collector, and PNP/NPN type).
3. The hFE value will be displayed on the LCD.

5.6 Backlight and Auto-Off

• شاته رڼا: فشار ورکړئ شاته څراغ button to illuminate the LCD display. Press it again to turn off the backlight.
• اتومات بند: میټر به د بیټرۍ د ژوند د خوندي کولو لپاره د شاوخوا 10 دقیقو غیر فعال کیدو وروسته په اتوماتيک ډول بند شي.

6. ساتنه

• پاکول: میټر په وچ او نرم ټوکر سره پاک کړئ. د کثافاتو یا محلولونو څخه کار مه اخلئ.
• د بیټرۍ بدلول: کله چې د ټیټ بیټرۍ شاخص په ډسپلې کې څرګند شي، د 9V بیټرۍ بدله کړئ لکه څنګه چې په 4.1 برخه کې تشریح شوي.
• ذخیره کول: If the meter is not used for a long period, remove the battery to prevent leakage and damage. Store in a cool, dry place.

7. ستونزه حل کول

• نه ښودنه: د بیټرۍ نصب کول وګورئ او ډاډ ترلاسه کړئ چې بیټرۍ کافي چارج لري.
• ناسم لوستل: Verify that the function switch is set to the correct range and that test leads are properly connected. Ensure the component under test is correctly prepared (e.g., discharged capacitors).
• "OL" یا "1" په ښودنه کې: This indicates an overload or out-of-range measurement. Select a higher range or check the circuit.
