3. Maklumat Keselamatan

To ensure safe operation and prevent damage to the meter, please read and follow all safety instructions carefully.

• Always ensure the meter is in good working condition before use. Do not use if the casing is damaged or if the test leads are frayed.
• Never exceed the maximum input limits for any measurement range. Refer to the specifications section for details.
• Berhati-hati apabila bekerja dengan voltagadalah melebihi 30V AC RMS, puncak 42V atau 60V DC. Ini voltagia menimbulkan bahaya kejutan.
• Sentiasa putuskan sambungan kuasa ke litar dan nyahcas semua voltan tinggitagkapasitor sebelum melakukan pengukuran rintangan, kesinambungan, diod atau kapasitans.
• Ensure the correct function and range are selected before connecting the test leads to the circuit.
• Connect the common (COM) test lead first, then the live test lead. Disconnect the live test lead first, then the common test lead.
• Gantikan bateri dengan segera apabila penunjuk bateri lemah muncul untuk memastikan bacaan yang tepat.
• Jangan kendalikan meter dalam gas meletup, wap atau persekitaran berdebu.

6.1. Pemasangan Bateri

The RuoShui 9205D Multimeter operates on a 9V battery. To install or replace the battery:

1. Pastikan multimeter dimatikan dan petunjuk ujian diputuskan.
2. Cari penutup petak bateri di belakang meter.
3. Tanggalkan skru penahan dan tanggalkan penutup.
4. Connect a new 9V battery to the battery clip, observing correct polarity.
5. Letakkan bateri di dalam petak dan gantikan penutup, selamatkannya dengan skru.

7.1. General Measurement Procedure

1. Insert the black test lead into the COM jack.
2. Insert the red test lead into the appropriate input jack (VΩmA or 10A) for the desired measurement.
3. Turn the rotary switch to the desired function and range. If the value is unknown, start with the highest range and decrease as necessary.
4. Sambungkan probe ujian ke litar atau komponen yang sedang diuji.
5. Baca nilai ukuran pada LCD.
6. Disconnect the test probes from the circuit.

7.2. Fungsi Pengukuran Khusus

• Voltage Measurement (DCV/ACV): Select the 'V—' for DC voltage or 'V~' for AC voltage. Connect probes in parallel with the circuit.
• Current Measurement (DCA/ACA): Select the 'A—' for DC current or 'A~' for AC current. Connect probes in series with the circuit. Use the 10A jack for high currents.
• Resistance Measurement (Ω): Select the 'Ω' range. Ensure the circuit is de-energized. Connect probes across the component.
• Pengukuran Kapasitans (F): Select the 'F' range. Ensure the capacitor is discharged before connecting probes.
• Inductance Measurement (H): Select the 'H' range. Connect probes across the inductor.
• Ujian Diod: Select the diode symbol. Connect the red probe to the anode and black probe to the cathode.
• Triode Test (hFE): Insert the transistor into the hFE socket, ensuring correct EBC/PNP/NPN configuration.
• Ujian Kesinambungan: Select the continuity symbol (buzzer). If resistance is below a certain threshold, the buzzer will sound.

7.3. Single Pen Live Wire Judgment

This function allows you to quickly check for the presence of AC voltage without needing both test leads.

1. Set the rotary switch to the 'Live' position.
2. Hold the multimeter firmly and touch the tip of the red test probe to the suspected live wire or terminal.
3. The display will indicate the presence of AC voltage, often with an 'L' or a specific symbol, and may emit an audible alert.
