3. Operating Instructions

The ANENG A3004 features a rotary table for function selection and buttons for additional controls like data retention, range switching, and unit switching.

General Operation:

Power On/Off: The device has an 'Auto Power Off' feature. To manually turn on, rotate the dial.
Rotary Table: Use the red rotary switch to select the desired measurement function (AC voltage, DC voltage, Capacitance/Buzzer/Diode/Resistance, NCV tests, Current (mA)).
HOLD/* Button: Press to retain the current data reading on the display. Long press for backlight.
RANGE Button: Press to switch between manual and auto ranging modes.
SELECT Button: Press to switch between different units or sub-functions within a mode (e.g., Diode, Buzzer, Capacitance).

Specific Measurement Modes:

DC Voltage Measurement

Rotate the dial to the DC voltage (V=) position. Connect the test leads to the circuit or component. The display will show the DC voltage reading. For example, when measuring a 9V battery, the display will show approximately 9V.

Measuring DC voltage of a 9V battery with the multimeter — Figure 4: Measuring DC voltage of a 9V battery. The display shows 0.960V, indicating a low battery.

Resistance Measurement

Rotate the dial to the Capacitance/Buzzer/Diode/Resistance (Ω) position. Touch one end of the stylus to one side of the resistor and the other test lead to the other side. The display will show the resistance value.

Measuring resistance of a component with the multimeter — Figure 8: Measuring resistance. The display shows 0.202Ω.

Diode Measurement

Rotate the dial to the Capacitance/Buzzer/Diode/Resistance (Ω) position and press the SELECT button to switch to diode mode. Connect the test leads to the positive and negative poles of the diode. The display will show the forward voltage drop.

Measuring a diode with the multimeter — Figure 9: Measuring a diode. The display shows 1.439V.

Capacitance Measurement

Rotate the dial to the Capacitance/Buzzer/Diode/Resistance (Ω) position and press the SELECT button to switch to capacitance mode. Touch the two sides of the capacitor with the test leads. The display will show the capacitance value.

Measuring capacitance of a capacitor with the multimeter — Figure 10: Measuring capacitance. The display shows 67.01uF.

Video: Capacitance Measurement Demonstration

NCV (Non-Contact Voltage) Detection

Rotate the dial to the NCV position. Bring the tip of the multimeter close to the object to be tested (e.g., a wall socket). If voltage is detected, the screen will sound a buzzer alarm and the indicator light will flash.

Performing an NCV test on a wall socket — Figure 11: NCV test on a wall socket. The device detects voltage and emits a sound.

Video: NCV Test Demonstration

Buzzer (Continuity) Measurement

Rotate the dial to the Capacitance/Buzzer/Diode/Resistance (Ω) position and press the SELECT button to switch to buzzer mode. Touch the test leads to the two points you want to check for continuity. If continuity is detected, the multimeter will make a "beep" sound.

Performing a buzzer (continuity) test with the multimeter — Figure 12: Buzzer test. The device beeps when continuity is detected.

Video: Buzzer Measurement Demonstration

Zero Fire Detection

Rotate the dial to the NCV position. Insert the gauge pen into the row insert of a power outlet. If it's the live wire (fire line), the multimeter will emit an alarm sound. If it's the neutral wire (zero line), there will be no alarm sound.

4. Maintenance

Cleaning: Use a soft, dry cloth to clean the multimeter. Do not use abrasive cleaners or solvents.
Battery Replacement: Replace batteries promptly when the low battery indicator appears on the display to ensure accurate readings. Refer to the 'Battery Installation' section for instructions.
Storage: When not in use for extended periods, remove the batteries and store the multimeter in a cool, dry place away from direct sunlight and extreme temperatures.

5. Troubleshooting

No Power: Check if batteries are correctly installed and have sufficient charge. Replace if necessary.
Inaccurate Readings: Ensure the correct measurement mode is selected and test leads are properly connected. Check for damaged test leads.
Display shows 'OL' or 'OVER': This indicates that the measured value is outside the selected range. Switch to a higher range or a different measurement function if applicable.
No NCV detection: Ensure the NCV function is selected and the tip is close enough to the voltage source.

If you encounter persistent issues, please contact ANENG customer service for assistance.

8. User Tips

Always ensure the multimeter is set to the correct function and range before making any measurements to prevent damage to the device or the circuit.
When measuring current, always connect the multimeter in series with the circuit.
For voltage measurements, connect the multimeter in parallel with the component.
Utilize the 'HOLD' function to freeze readings on the display, especially in hard-to-read situations.
The automatic shutdown feature helps conserve battery life; remember to turn the dial to 'OFF' when finished for longer storage.
