6.2 Nyambungkeun Test Leads

Sambungkeun kabel tés kalayan leres pikeun pangukuran anu akurat sareng aman:

1. Selapkeun lead test hideung kana COM (common) jack.
2. Kanggo sabagéan ageung pangukuran (voltage, resistance, diode, hFE, and current up to 200mA), insert the red test lead into the VΩmA jack.
3. Pikeun pangukuran arus tinggi (nepi ka 10A), selapkeun lead test beureum kana 10A jack.

7. Parentah Operasi

Before making any measurement, ensure the test leads are correctly connected and the rotary switch is set to the appropriate function and range.

7.1 Ngukur DC Voltage (V=)

1. Selapkeun kalungguhan beureum kana VΩmA jack and the black lead into the COM jack.
2. Setel saklar puteran kana Voltase DC anu dipikahoyongtage (V=) range. Start with the highest range if the voltage teu kanyahoan.
3. Connect the test leads across the component or circuit to be measured (in parallel).
4. Baca voltage value on the LCD display. The display will show the correct polarity.

7.2 Ngukur AC Voltage (V~)

1. Selapkeun kalungguhan beureum kana VΩmA jack and the black lead into the COM jack.
2. Setel saklar puteran kana Voltase AC anu dipikahoyongtage (V~) range. Start with the highest range if the voltage teu kanyahoan.
3. Connect the test leads across the component or circuit to be measured (in parallel).
4. Baca voltage nilai dina tampilan LCD.

7.3 Measuring DC Current (A=)

Caution: Never connect the multimeter in parallel with a voltage sumber nalika ngukur arus, sakumaha ieu bisa niup sekering atawa ngaruksak méter.

1. Determine the expected current. For currents up to 200mA, insert the red lead into the VΩmA jack. For currents up to 10A, insert the red lead into the 10A jack. Always insert the black lead into the COM jack.
2. Set the rotary switch to the appropriate DC Current (A=) range. Start with the highest range if the current is unknown.

3. Sambungkeun kabel beureum ka anoda sareng kabel hideung ka katoda dioda. Layar bakal nunjukkeun voltase majutage drop (typically 0.5V to 0.8V for silicon diodes).
4. Reverse the leads. The display should show 'OL' (Overload) for a good diode. If it shows a reading in both directions or 'OL' in both directions, the diode may be faulty.

7.6 Transistor (hFE) Test

Caution: Ensure the transistor is disconnected from the circuit before testing.

1. Selapkeun kalungguhan beureum kana VΩmA jack and the black lead into the COM jack.
2. Atur switch Rotary ka posisi hFE.
3. Identify if the transistor is NPN or PNP. Insert the transistor's emitter, base, and collector leads into the corresponding holes in the hFE socket on the multimeter.
4. Read the hFE (DC current gain) value on the LCD display.

• Teu aya tampilan atanapi tampilan anu samar: Pariksa batréna. Ganti upami diperyogikeun.
• Bacaan anu salah:
• Ensure the rotary switch is set to the correct function and range.
• Pariksa batré voltage; replace if low.
• Pastikeun lead test disambungkeun leres tur teu ruksak.
• For resistance measurements, ensure the circuit is de-energized.
• 'OL' (Overload) ditampilkeun: The measured value exceeds the selected range. Select a higher range or ensure the circuit is within the meter's capabilities.
• Fuse blown (during current measurement): If the meter stops measuring current, the internal fuse may have blown. Refer to a qualified technician for fuse replacement.
