2. Maklumat Keselamatan

Always read and understand all safety warnings and operating instructions before using this multimeter. Failure to do so may result in injury or damage to the instrument.

• Jangan melebihi nilai input maksimum untuk sebarang julat.
• Gunakan sangat 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, without any damaged insulation.
• Always connect the common (black) test lead first, then the live (red) test lead. Disconnect the live test lead first.
• Do not use the multimeter if it appears damaged or is not operating correctly.
• Gantikan bateri dengan segera apabila penunjuk bateri lemah muncul untuk memastikan bacaan yang tepat.
• Simpan jari di belakang pelindung jari pada probe ujian semasa pengukuran.

1. Magnetoelectric DC Ammeter Dial: Displays measurement readings using a needle.
2. Mechanical Zero Adjuster: Knob used to set the needle to the zero position when no input is applied.
3. Resistance Zero Adjuster (Ω ADJ): Knob used to zero the needle for resistance measurements.
4. Support Design: A built-in stand at the back for convenient placement during use.
5. Pelabuhan Input: Terminal untuk menyambungkan petunjuk ujian.

3.2 Display Dial

The multimeter features a clear analog dial with multiple scales for different measurement types. Familiarize yourself with these scales before operation.

Rajah 3.2: Terperinci view of the analog display dial.

• OHMS Scale: Used for resistance measurements.
• DC/AC Scales: Used for DC and AC voltage dan ukuran semasa.
• dB Scale: Used for decibel measurements.
• hFE Scale: Used for transistor gain measurements.

4. Persediaan

4.1 Pemasangan Bateri

The RuoShui 3010 requires 2 AAA batteries and 1 9V battery for operation. These are typically included.

1. Cari penutup petak bateri di belakang multimeter.
2. Tanggalkan skru penahan dan tanggalkan penutup.
3. Insert the batteries, observing correct polarity (+ and -).
4. Replace the cover and secure it with the screw(s).

4.2 Connecting Test Probes

Connect the red and black test probes to the appropriate input jacks on the multimeter.

• Sambungkan hitam ujian membawa kepada -COM (Umum) jek.
• Sambungkan merah ujian membawa kepada VΩmA+ jack for most voltage, resistance, and current measurements. For high current (10A) measurements, use the dedicated 10A jack if available and specified on the device.

4.3 Mechanical Zero Adjustment

Before taking any measurements, ensure the needle is aligned with the zero mark on the scale. If not, use the mechanical zero adjuster knob (usually a small screw below the dial) to carefully align it.

4.4 Resistance Zero Adjustment

For resistance measurements, after selecting the OHM range, short the red and black test leads together. The needle should move to the zero mark on the OHMS scale. If it does not, use the Ω ADJ knob to adjust it to zero. This must be done for each resistance range selected.

5. Arahan Operasi

Always select the appropriate measurement function and range before connecting the test leads to the circuit under test. If the value is unknown, start with the highest range and work downwards.

Figure 5.1: Rotary switch for selecting measurement functions and ranges.

5.1 DC Jldtage Pengukuran (DCV)

1. Set the rotary switch to the desired DCV range (e.g., 10V, 50V, 250V, 1000V).
2. Sambungkan petunjuk ujian merah ke sisi positif (+) litar dan petunjuk ujian hitam ke sisi negatif (-).
3. Baca voltage value from the DCV scale on the display.

5.2 AC Jldtage Pengukuran (ACV)

1. Set the rotary switch to the desired ACV range (e.g., 10V, 50V, 250V, 1000V).
2. Sambungkan petunjuk ujian merentasi vol ACtage sumber.
3. Baca voltage value from the ACV scale on the display.

5.3 Pengukuran Arus DC (DCA)

Caution: Never connect the multimeter in parallel with a voltage source when measuring current. This can damage the multimeter and the circuit.

1. Set the rotary switch to the desired DCA range (e.g., 50µA, 2.5mA, 50mA, 500mA, 10A).
2. Pecah litar and connect the multimeter in series with the load. The current must flow through the multimeter.
3. Read the current value from the DCA scale on the display.

5.4 Pengukuran Rintangan (Ω)

1. Pastikan litar yang diuji adalah hilang tenaga sebelum mengukur rintangan.
2. Set the rotary switch to the desired OHMS (Ω) range (e.g., x1, x10, x100, x1k, x10k).
3. Perform the resistance zero adjustment as described in Section 4.4.
4. Sambungkan wayar ujian merentasi komponen atau litar yang hendak diukur.
5. Read the resistance value from the OHMS scale. Multiply the reading by the selected range multiplier.

5.5 Transistor (hFE) Test

This function is used to measure the DC current gain (hFE) of NPN and PNP transistors.

1. Tetapkan suis putar ke hFE kedudukan.
2. Insert the transistor leads into the corresponding NPN or PNP sockets on the multimeter.
3. Read the hFE value from the hFE scale on the display.

6. Penyelenggaraan

6.1 Pembersihan

Lap multimeter casing dengan iklanamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is dry before use.

6.2 Penggantian Bateri

Replace batteries when the low battery indicator appears or if the multimeter does not power on. Refer to Section 4.1 for battery installation instructions.

6.3 Penyimpanan

Apabila tidak digunakan untuk tempoh yang lama, tanggalkan bateri untuk mengelakkan kebocoran. Simpan multimeter di tempat yang sejuk dan kering, jauh daripada cahaya matahari langsung dan suhu yang melampau.

7. Penyelesaian masalah

• Tiada masalah paparan/Kuasa: Periksa pemasangan bateri dan cas. Gantikan bateri jika perlu.
• Bacaan yang salah: Ensure the correct function and range are selected. Check test lead connections. Perform mechanical and resistance zero adjustments.
• No continuity/resistance reading: Pastikan litar dinyahtenagakan. Periksa petunjuk ujian untuk kerosakan.
