4. Setup

4.1 Battery Installation

The ANENG A3015 requires two 1.5V AAA batteries (not included) for operation.

1. Using the provided Phillips screwdriver, unscrew and remove the back cover of the multimeter.
2. Insert two AAA batteries, ensuring correct polarity (+/-).
3. Replace the back cover and secure it with the screw.

Figure 4: Battery installation for the multimeter.

4.2 Connecting Test Leads

Connect the spring test pen line to the COM jack at the bottom of the multimeter. The spring test pen line is retractable and can stretch up to approximately 1.6 meters (62.99 inches), providing flexibility during measurements.

5. Operating Instructions

5.1 Power On/Off and Backlight

• Power On: Long press the Power button (6) for 2 seconds. The display will show "Auto" indicating automatic mode.
• Power Off: Long press the Power button (6) for 2 seconds.
• Backlight: Short press the Power button (6) to turn the LCD backlight on or off for convenient night reading.

5.2 Automatic Identification Mode

When powered on, the multimeter defaults to automatic identification mode, which can automatically recognize and measure AC/DC voltage, resistance, and continuity.

• AC/DC Voltage Detection: Connect the probe to the circuit. The meter will automatically display the voltage and identify if it's AC or DC. For DC voltage, it differentiates between positive and negative poles.
• Resistance Testing: Connect the probe across the component. The meter will automatically display the resistance value.
• On-Off Beep (Continuity): Connect the probe across the circuit. If the resistance of the tested line is less than 50Ω, the buzzer will sound, and the backlight will turn bright red. This is useful for checking car line fuses.

5.3 Live/Naught Line Detection

To perform live/naught line detection:

1. Press the Function switch key (5) until "LIVE" is displayed.
2. Touch the probe to the live line: The screen will display "---H" with a beep and flash red.
3. Touch the probe to the naught line: The screen will display "Live" without a beep.

5.4 NCV Voltage Induction (Non-Contact Voltage)

To detect AC voltage without direct contact:

1. Press the Function switch key (5) until "NCV" is displayed.
2. Move the probe close to the wire or electrical field.
3. The stronger the electric field, the more frequently the screen will flash red and beep.
4. Press the H/L LIVE key (4) to switch between high (HI) and low (LO) sensitivity for NCV detection. High sensitivity allows detection from a farther distance.

5.5 Phase Sequence Detection

To determine the phase sequence of a three-phase electricity line:

1. Press the Function switch key (5) until "Phase" is displayed.
2. Touch the tip of the probe to the first line (A) of the three-phase system. Wait for the buzzer to beep.
3. Touch the tip of the probe to the second line (B). Wait for the buzzer to beep.
4. Touch the tip of the probe to the third line (C). Wait for the buzzer to beep.
5. The multimeter will indicate whether the phase sequence is forward or reverse.

5.6 Line Breakpoint Lookup

Use the NCV mode to locate breakpoints in a line:

• Switch to NCV mode.
• Move the probe along the wire.
• A strong alarm indicates a continuous line.
• A weak or absent signal indicates the position where the line is disconnected (breakpoint).

5.7 Automotive Circuit Measurement

The ANENG A3015 is suitable for various automotive circuit detection tasks, including automatic recognition of AC/DC voltage, resistance, and on-off test functions for troubleshooting fuses and other components.

5.8 Data Hold Function

Press the HOLD button (3) to freeze the current reading on the display. Press it again to release the hold function.

5.9 Automatic Shutdown

The multimeter will automatically shut down after 15 minutes of no operation to conserve battery life.

6. Specifications

Note: The parameters are for reference only, and the actual measurement of the specific equipment shall prevail.

7. Maintenance

• Cleaning: Wipe the multimeter with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace batteries when the low power prompt appears on the display. Refer to section 4.1 for battery installation instructions.
• Storage: Store the multimeter in a cool, dry place away from direct sunlight and extreme temperatures. Always place the protective cap on the probe when not in use to prevent injuries.

8. Troubleshooting

• Multimeter does not power on: Check if the batteries are installed correctly and have sufficient charge. Replace batteries if necessary.
• Inaccurate readings: Ensure the probes are making good contact with the circuit. Verify the correct function mode is selected (though automatic mode handles most common measurements).
• No NCV detection: Ensure the multimeter is in NCV mode and try switching between high and low sensitivity.
• Buzzer not sounding during continuity test: Check if the circuit resistance is above 50Ω, or if the multimeter is not in the correct mode.

If you encounter persistent issues, please refer to the warranty and support section for further assistance.

9. User Tips

• The compact size of the ANENG A3015 makes it ideal for carrying in a pocket or tool belt for quick diagnostics on the go.
• Leverage the automatic identification feature to simplify measurements; it reduces the need to manually select ranges for common tasks like voltage and resistance.
• Always utilize the LCD backlight for clear readings, especially when working in dimly lit environments or at night.
• The retractable spring wire offers excellent flexibility and reach, making it convenient for testing in tight spaces or across longer distances without tangling.
