4. Persediaan

4.1. Pemasangan Bateri

The VOLTCRAFT VC-440 E requires one 9V battery (included). To install or replace the battery:

1. Ensure the multimeter is turned OFF and all test leads are disconnected from the device and any circuit.
2. Locate the battery compartment on the back of the multimeter (refer to Figure 3.2).
3. Unscrew the retaining screw(s) for the battery cover.
4. Tanggalkan penutup bateri dengan berhati-hati.
5. Sambungkan bateri 9V ke klip bateri, perhatikan polariti yang betul.
6. Letakkan bateri ke dalam petak.
7. Gantikan penutup bateri dan kencangkannya dengan skru.

Note: A low battery indicator will appear on the display when the battery needs replacement.

5. Arahan Operasi

Before any measurement, ensure the test leads are correctly inserted into the appropriate input jacks and the rotary switch is set to the desired function.

5.1. Mengukur DC Voltage (V-)

1. Insert the red test lead into the VΩHz jack and the black test lead into the COM jack.
2. Turn the rotary switch to the V- position.
3. Sambungkan wayar ujian merentasi komponen atau litar yang hendak diukur.
4. Baca voltagnilai e pada paparan.

5.2. Mengukur Vol ACtage (V~)

1. Insert the red test lead into the VΩHz jack and the black test lead into the COM jack.
2. Turn the rotary switch to the V~ position.
3. Sambungkan wayar ujian merentasi komponen atau litar yang hendak diukur.
4. Baca voltagnilai e pada paparan.

5.3. Mengukur Rintangan (Ω)

1. Pastikan litar dinyahtenagakan sebelum mengukur rintangan.
2. Insert the red test lead into the VΩHz jack and the black test lead into the COM jack.
3. Turn the rotary switch to the Ω position. If necessary, press SELECT to cycle to resistance measurement.
4. Sambungkan petunjuk ujian merentasi komponen.
5. Baca nilai rintangan pada paparan.

5.4. Measuring Current (A~ / A-)

AWAS: Jangan sekali-kali sambungkan multimeter selari dengan voltage source when measuring current. Always connect it in series with the load.

1. De-energize the circuit and open it at the point where current is to be measured.
2. For currents up to 600mA, insert the red test lead into the mAµA jack. For currents up to 10A, insert the red test lead into the 10A jack. Insert the black test lead into the COM jack.
3. Turn the rotary switch to the appropriate A~ or A- position. Use SELECT to choose AC or DC current if needed.
4. Sambungkan petunjuk ujian secara bersiri dengan litar.
5. Tenagakan semula litar dan baca nilai semasa pada paparan.

5.5. Mengukur Kekerapan (Hz)

1. Insert the red test lead into the VΩHz jack and the black test lead into the COM jack.
2. Putar suis berputar ke kedudukan Hz.
3. Sambungkan wayar ujian merentasi sumber isyarat.
4. Baca nilai kekerapan pada paparan.

6. Penyelenggaraan

6.1. Pembersihan

Lap multimeter casing dengan iklanamp kain dan detergen yang lembut. Jangan gunakan bahan kasar atau pelarut. Pastikan peranti kering sepenuhnya sebelum digunakan.

6.2. Penggantian Bateri

Refer to Section 4.1 for detailed instructions on battery replacement. Always use a fresh 9V battery.

6.3. Penggantian fius

The current input jacks (mAµA and 10A) are protected by fuses. If current measurements fail, the fuse may need replacement. Fuse replacement should only be performed by qualified personnel. Refer to the full technical manual for fuse specifications and replacement procedures.

7. Penyelesaian masalah

• Tiada paparan atau paparan samar: Check battery charge. Replace the 9V battery if necessary.
• Bacaan yang salah:
  • Ensure test leads are correctly inserted and making good contact.
  • Verify the rotary switch is set to the correct function and range.
  • Periksa petunjuk ujian yang rosak.
  • Ensure the circuit is de-energized for resistance measurements.
• Pengukuran semasa tidak berfungsi: Check the fuse for the relevant current input (mAµA or 10A). Replace if blown (refer to Section 6.3).
• "OL" or "OVERLOAD" on display: The measured value exceeds the selected range. Switch to a higher range or ensure the input is within the device's maximum specifications.
