pengenalan

This user manual provides essential information for the safe and effective operation of your DigiTech Cat III Multimeter with Temperature, model QM1323. Please read this manual thoroughly before use and retain it for future reference.

The DigiTech QM1323 is a compact, battery-powered multimeter designed for various electrical measurements, including voltage, current, resistance, frequency, capacitance, and temperature. It is rated for CAT III applications, ensuring safety for measurements in building installations.

Maklumat Keselamatan

Always adhere to the following safety precautions to prevent personal injury or damage to the multimeter:

• Jangan melebihi had input maksimum untuk sebarang fungsi.
• Berhati-hati apabila bekerja dengan voltagadalah melebihi 30V AC RMS, puncak 42V atau 60V DC. Ini voltagia menimbulkan bahaya kejutan.
• Ensure the test leads are in good condition and properly seated in the input jacks.
• Jangan kendalikan multimeter jika ia kelihatan rosak atau jika bekasnya terbuka.
• Always turn off power to the circuit under test before connecting or disconnecting test leads for current measurements.
• Gantikan bateri apabila penunjuk bateri rendah muncul untuk memastikan bacaan yang tepat.

Persediaan

Pemasangan Bateri:

The DigiTech QM1323 requires one 9V battery (included). To install or replace the battery:

1. Pastikan multimeter dimatikan.
2. Cari petak bateri di bahagian belakang unit.
3. Tanggalkan skru penahan dan tanggalkan penutup bateri.
4. Sambungkan bateri 9V ke klip bateri, perhatikan polariti yang betul.
5. Letakkan bateri ke dalam petak dan gantikan penutup, selamatkannya dengan skru.

Menghubungkan Petunjuk Ujian:

Sentiasa sambungkan petunjuk ujian hitam ke COM jack. Connect the red test lead to the appropriate input jack based on the measurement type:

• VΩTemp: Untuk voltage, resistance, continuity, diode, capacitance, frequency, and temperature measurements.
• mAµA: For current measurements up to 400mA.
• 10A: Untuk pengukuran arus sehingga 10A.

Arahan Operasi

This section details how to perform common measurements with your multimeter.

Mengukur DC Voltage:

1. Putar dail fungsi ke V position. The display will show "DC".
2. Sambungkan plumbum ujian hitam ke COM bicu dan ujian merah membawa kepada VΩTemp jek.
3. Sambungkan petunjuk ujian secara selari merentasi vol DCtage sumber atau komponen yang hendak diukur.
4. Baca voltagnilai e pada paparan LCD.

Mengukur Vol ACtage:

1. Putar dail fungsi ke V kedudukan.
2. Tekan ke MODE button to toggle to "AC".
3. Sambungkan plumbum ujian hitam ke COM bicu dan ujian merah membawa kepada VΩTemp jek.
4. Sambungkan petunjuk ujian secara selari merentasi vol ACtage sumber atau komponen yang hendak diukur.
5. Baca voltagnilai e pada paparan LCD.

Mengukur Rintangan:

1. Putar dail fungsi ke Ω kedudukan.
2. Sambungkan plumbum ujian hitam ke COM bicu dan ujian merah membawa kepada VΩTemp jek.
3. Pastikan litar atau komponen dinyahtenagakan sebelum menyambungkan petunjuk ujian.
4. Connect the test leads across the component whose resistance is to be measured.
5. Baca nilai rintangan pada paparan LCD.

Mengukur Suhu:

1. Putar dail fungsi ke Temp kedudukan.
2. Connect the temperature probe (if included) to the COM dan VΩTemp bicu, memerhati kekutuban.
3. Letakkan hujung probe suhu pada atau berhampiran objek yang suhunya hendak diukur.
4. Read the temperature value on the LCD display. The unit may be switchable between Celsius and Fahrenheit using the MODE button.

Penyelenggaraan

Pembersihan:

Untuk membersihkan multimeter, lap bekas dengan iklanamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the unit is completely dry before use.

Penggantian fius:

If the current measurement function (10A or mAµA) stops working, the internal fuse may need replacement. Refer to the specifications for the correct fuse type and rating. Fuse replacement typically involves opening the back case of the multimeter. If unsure, consult a qualified technician.

Storan:

When not in use for extended periods, turn the multimeter OFF and remove the battery to prevent leakage. Store the multimeter in a cool, dry place, ideally in its protective case.
