The VOLTCRAFT VC-750 E is a versatile digital clamp meter designed for non-contact AC/DC current measurement and comprehensive multimeter functions. This device allows for current measurements without interrupting the circuit, making it ideal for electricians, technicians, and service personnel. Its robust, splash-proof (IP54) design ensures reliable operation in demanding environments.

2. Maklumat Keselamatan

Always adhere to safety precautions when operating electrical measuring devices. Failure to do so may result in injury or damage to the device. This device is rated CAT IV 600 V, indicating its suitability for measurements at the source of the low-voltage pemasangan, seperti meter elektrik dan peranti perlindungan arus lebih utama.

• Pastikan peranti berada dalam keadaan baik sebelum digunakan.
• Jangan melebihi nilai input maksimum untuk sebarang fungsi.
• Use only the provided test leads or equivalent safety-rated accessories.
• Avoid contact with live circuits.
• Do not operate the device in wet conditions or explosive atmospheres. The IP54 rating protects against dust and splashing water, but not immersion.
• Gantikan bateri apabila penunjuk bateri lemah muncul.

6. Arahan Operasi

6.1 Hidupkan/Mati Kuasa

Turn the rotary switch from the OFF position to the desired measurement function to power on the device. Turn it back to OFF to power off.

6.2 Pengukuran Arus AC/DC (Clamp Fungsi)

This function allows non-contact current measurement.

1. Set the rotary switch to the “A” (Ampere) range for AC or DC current.
2. Tekan clamp pencetus untuk membuka clamp Rahang.
3. Sertakan konduktor tunggal dengan clamp rahang. Pastikan rahang ditutup sepenuhnya.
4. Baca nilai semasa pada paparan.

6.3 Jldtage Pengukuran (AC/DC)

1. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 5.2.
2. Set the rotary switch to the “V” (Voltage) range for AC or DC voltage.
3. Sambungkan prob ujian secara selari dengan litar atau komponen yang hendak diukur.
4. Baca voltagnilai e pada paparan.

6.4 Pengukuran Rintangan

1. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 5.2.
2. Set the rotary switch to the “Ω” (Ohm) range.
3. Pastikan litar atau komponen dinyahtenagakan sebelum mengukur rintangan.
4. Sambungkan kuar ujian merentasi komponen.
5. Baca nilai rintangan pada paparan.

6.5 Pengukuran Kapasitansi

1. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 5.2.
2. Set the rotary switch to the “CAP” (Capacitance) range.
3. Pastikan kapasitor dinyahcas sepenuhnya sebelum pengukuran.
4. Sambungkan kuar ujian merentasi kapasitor.
5. Baca nilai kapasitans pada paparan.

6.6 Diode Test and Continuity

1. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 5.2.
2. Set the rotary switch to the “Ω” (Ohm) range and use the function button to select Diode Test or Continuity.
3. For diode test, connect the probes across the diode. The forward voltage drop akan dipaparkan.
4. For continuity, connect the probes across the circuit. An audible tone indicates continuity.

6.7 Fungsi Khas

• TrueRMS Measurement: The VC-750 E provides TrueRMS measurements for accurate readings of non-sinusoidal AC waveforms.
• 3-Phase Rotation Tester with Low-Pass Filter: Use this function for testing 3-phase systems. Refer to the specific instructions in the full manual for detailed usage.
• Paparan Graf Bar: The 31-segment bar graph provides a quick visual indication of measurement trends.
• Pegangan Data: Press the HOLD button (refer to Figure 4.2) to freeze the current reading on the display. Press again to release.

7. Penyelenggaraan

7.1 Pembersihan

Clean the device regularly with a dry, lint-free cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and test leads are disconnected before cleaning.
