Persediaan

Pemasangan Bateri

The Fluke 355 requires six 1.5V AA batteries for operation. These are typically included with your purchase.

1. Cari penutup petak bateri di bahagian belakang peranti.
2. Gunakan pemutar skru untuk membuka penutup.
3. Insert the six AA batteries, ensuring correct polarity (+/-).
4. Gantikan penutup petak bateri dan selamatkannya.

Pemeriksaan Awal

Before first use, inspect the clamp-meter, test leads, and accessories for any signs of damage. Do not use the device if any damage is observed.

Arahan Operasi

Menghidupkan/Mematikan

Turn the rotary switch to any measurement function to power on the device. Turn the rotary switch to "OFF" to power off. The device will automatically power off after 20 minutes of inactivity to conserve battery life.

Measuring AC/DC Current (Clamp Fungsi)

1. Turn the rotary switch to the "A AC+DC" position.
2. Tekan tuil pelepas rahang untuk membuka penutupamp rahang.
3. Letakkan clamp jaws around a single conductor. Ensure the jaws are fully closed.
4. Baca nilai semasa pada LCD.

Mengukur Voltage (AC/DC)

1. Connect the test leads to the appropriate input jacks (COM and V).
2. Turn the rotary switch to the "V AC+DC" position.
3. Sambungkan kuar ujian merentasi litar atau komponen yang hendak diukur.
4. Baca voltagnilai e pada LCD.

Mengukur Rintangan (Ω)

1. Connect the test leads to the appropriate input jacks (COM and Ω).
2. Putar suis putar ke kedudukan "Ω".
3. Pastikan litar dinyahtenagakan sebelum mengukur rintangan.
4. Sambungkan kuar ujian merentasi komponen yang hendak diukur.
5. Baca nilai rintangan pada LCD.

Fungsi Lain

• RANGE: Manually select the measurement range if auto-ranging is not desired.
• DIBERI: Tekan untuk membekukan bacaan semasa pada paparan. Tekan sekali lagi untuk melepaskan.
• SIFAR: Used to zero out DC current readings or resistance readings for lead compensation.
• Hz: Measures frequency.
• MASUK: Measures the peak current during motor startup.
• MIN MAX: Toggles through minimum, maximum, and average readings captured during a measurement session.
• PENAPIS: Activates a low-pass filter to reduce electrical noise for stable readings.

Penyelenggaraan

Pembersihan

Bersihkan meter casing dengan iklanamp kain dan detergen lembut. Jangan gunakan bahan kasar atau pelarut. Pastikan paparan bersih dan kering.

Penggantian Bateri

When the low-battery indicator appears on the display, replace all six AA batteries promptly to ensure accurate measurements. Follow the battery installation steps outlined in the Setup section.

Penyimpanan

Simpan clamp-meter in its soft carrying case in a dry, dust-free environment when not in use. Remove batteries if storing for extended periods to prevent leakage.

Menyelesaikan masalah

If the Fluke 355 Clamp-Meter is not functioning as expected, consider the following:

• Tiada Paparan/Kuasa: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary. Ensure the rotary switch is not in the "OFF" position.
• Bacaan Tidak Tepat: Verify that the correct measurement function is selected. Ensure test leads are properly connected and not damaged. For current measurements, ensure the clamp jaws are fully closed around a single conductor.
• Continuity Buzzer Not Working: Ensure the device is in the continuity measurement mode and the circuit is de-energized.

For persistent issues, refer to the official Fluke support resources or contact customer service.
