2. Maklumat Keselamatan
WARNING: Always exercise extreme caution when working with electricity. This device is an indicator and should not be solely relied upon for verifying the absence of voltage in critical safety situations. Always follow local electrical safety codes and use appropriate personal protective equipment.
- Jangan gunakan peranti jika ia kelihatan rosak atau tidak beroperasi dengan betul.
- Pastikan petak bateri ditutup dengan selamat sebelum digunakan.
- Jangan cuba mengukur voltages exceeding the specified range (1000V AC).
- Jauhkan peranti daripada air dan kelembapan.
- The laser light should not be pointed directly at eyes or reflective surfaces.

4.1 Pemasangan Bateri
The HANMATEK AC2 requires 2 AAA batteries (included). Ensure correct polarity when inserting.
- Unscrew the battery cover at the top of the device.
- Insert two AAA batteries according to the polarity markings (+/-) inside the compartment.
- Replace the battery cover and screw it tightly to secure.

5. Arahan Operasi
5.1 Hidupkan/Mati Kuasa
Tekan ke Butang Kuasa (green circle) to turn the device on. Press and hold the Power Button to turn it off.
5.2 Jldtage Pengesanan (Mod NCV)
The device automatically enters NCV (Non-Contact Voltage) detection mode upon power-on.
- Hold the device with the NCV probe tip near the conductor, socket, or wire you wish to test.
- Sekiranya AC voltage is detected, the Voltage Signal Indicator will light up (red), and an audible buzzer will sound. The LCD display will show the detected signal strength (H for High, L for Low).
- The intensity of the light and sound indicates the strength of the detected voltage.

5.3 Pelarasan Sensitiviti
The HANMATEK AC2 offers 9 levels of sensitivity, allowing detection from 12V AC to 1000V AC.
- Tekan ke Sensitivity Up Key (up arrow) to increase sensitivity.
- Tekan ke Sensitivity Down Key (down arrow) to decrease sensitivity.
- The LCD will display the current sensitivity level (1-9). Higher numbers indicate higher sensitivity, allowing detection of weaker signals or through thicker insulation.

5.4 Live/Neutral Wire Differentiation
When testing a live socket or wire, the device can help differentiate between live and neutral lines:
- Set the sensitivity to a lower level (e.g., 1 or 2) for more precise detection.
- Place the NCV probe near each terminal or wire.
- The live wire will typically trigger a stronger and more consistent indication (faster flashing light, louder buzzer) compared to the neutral wire.
5.5 Fungsi Lampu Suluh LED
Tekan ke Butang Lampu Suluh (light bulb icon) to turn the integrated LED flashlight on or off. This is useful for working in dimly lit areas.
5.6 Laser Pointer Function
Tekan ke Suis Laser (star icon) to activate the red laser pointer. Press it again to turn it off. This feature can be used for pointing or indicating specific areas.

5.7 Penutupan Automatik
To conserve battery life, the device will automatically shut down after approximately 3 minutes of inactivity or no signal detection.
5.8 Petunjuk Bateri Rendah
Jika bateri voltage drops below approximately 2.6V, the operating display will flash three times, and the buzzer will sound before the device automatically shuts down. Replace the batteries promptly when this occurs.
6. Penyelenggaraan
6.1 Penggantian Bateri
When the low battery indicator appears or the device fails to power on, replace the batteries as described in Section 4.1. Always use fresh AAA batteries.
6.2 Pembersihan
Lap peranti dengan kain kering dan lembut. Jangan gunakan pembersih atau pelarut yang kasar. Pastikan tiada kelembapan memasuki peranti.
6.3 Penyimpanan
If the device will not be used for an extended period, remove the batteries to prevent leakage and damage. Store in a cool, dry place away from direct sunlight.
7. Penyelesaian masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Peranti tidak dihidupkan. | Bateri mati atau tidak dipasang dengan betul. | Gantikan bateri, pastikan polariti yang betul. |
| Tiada jilidtage detected, but power is present. | Low sensitivity setting; device too far from source; very weak signal. | Increase sensitivity using the Up Key; move closer to the conductor. |
| False positive detection (detects voltage di mana tiada satu pun yang wujud). | High sensitivity setting; interference from nearby electrical fields. | Decrease sensitivity using the Down Key; ensure no other strong electrical sources are nearby. |
| Low battery indicator flashes. | Bateri hampir habis. | Gantikan bateri dengan segera. |
