Safety Information

Please read and understand all safety warnings and operating instructions before using this product. Failure to do so may result in electric shock, fire, or serious injury.

• Maximum Allowable Voltage: Do not exceed 1000V DC or 750V AC (RMS) between the measuring terminal and earth.
• Safe Voltage: Voltage below 36V is generally considered a safe voltage. Exercise extreme caution when working with higher voltages.
• Probe Handling: When the meter is connected to the measurement circuit, do not touch the metal part of the probe tips. During measurement, if the measured voltage is higher than 60V DC or 30V AC (effective value), keep your fingers behind the watch pen finger guard device.
• Function/Range Changes: When changing functions and ranges, the test leads should be moved away from the test point.
• Resistance/Continuity/Capacitance/Temperature Measurement: Do not attempt to measure resistance, line connection, capacitance, or temperature on a live circuit or when the device is charging.
• Current Measurement: Current measurements must be performed with the multimeter connected IN SERIES with the circuit. Failure to do so can damage the multimeter and the circuit.

Specific Measurements

AC Voltage Measurement

The multimeter automatically identifies AC voltage. Insert the test leads into the appropriate jacks (COM and VΩHz) and touch the probes to the AC source. The screen will display the voltage and frequency.

Figure: Measuring AC Voltage

DC Voltage Measurement

The multimeter automatically identifies DC voltage. Insert the test leads into the appropriate jacks (COM and VΩHz) and touch the probes to the DC source (e.g., battery terminals). Ensure correct polarity for accurate readings.

Figure: Measuring DC Voltage

AC/DC Current Measurement

IMPORTANT: Current measurements must be performed with the multimeter connected IN SERIES with the circuit. Failure to do so can damage the multimeter and the circuit.

1. Turn off power to the circuit.
2. Break the circuit at the point where you want to measure current.
3. Insert the red test lead into the 10A current input jack (5) and the black test lead into the COM jack (6).
4. Connect the multimeter in series with the circuit, ensuring the current flows through the multimeter.
5. Restore power to the circuit. The multimeter will automatically identify and display the AC or DC current.

Figure: Correct Series Connection for Current Measurement

Resistance Measurement

Insert the test leads into the COM (6) and VΩHz (7) jacks. Touch the probes to the component to measure resistance. The multimeter will display the resistance value.

Figure: Measuring Resistance

Diode Test

Insert the test leads into the COM (6) and VΩHz (7) jacks. Select the diode test function. Touch the probes to the diode. The multimeter will display the forward voltage drop. For LEDs, it will light up if functioning correctly.

Capacitance Measurement

WARNING: Before measuring capacitance, ensure the capacitor is fully discharged by short-circuiting its terminals. Insert the test leads into the COM (6) and VΩHz (7) jacks. Select the capacitance function and touch the probes to the capacitor terminals. The multimeter will display the capacitance value.

Figure: Measuring Capacitance

Frequency/Duty Cycle Measurement

Insert the test leads into the COM (6) and VΩHz (7) jacks. Select the frequency function. Connect the probes to the signal source. The multimeter will display the frequency (Hz) and duty cycle (%).

Figure: Measuring Frequency

Temperature Measurement

Plug the temperature probe into the COM (6) and VΩHz (7) jacks. Select the temperature function. Place the tip of the probe on the object whose temperature you wish to measure. The display will show the temperature in both Celsius and Fahrenheit.

Figure: Measuring Temperature

NCV (Non-Contact Voltage) Sensing

Long press the HOLD Button (2) to activate NCV mode. Move the multimeter's NCV sensing region (8) close to a live wire or electrical outlet. The device will detect AC voltage without physical contact, indicated by an alarm and visual cues on the screen.

Operating Instructions (B05 Screwdriver Electric Pen)

Zero Live Wire Determination

Touch the top metal cap of the pen with your hand. Insert the pen tip into a socket. If the green light illuminates, it indicates a zero line. If both red and green lights illuminate, it indicates a live wire (FireWire).

Figure: Zero Live Wire Detection

Non-Contact Voltage Sensing

Hold the screwdriver pen near an AC voltage source without direct contact. The LED green light in the middle of the pen will light up if AC voltage is detected.

Figure: Non-Contact Voltage Sensing

Line Breakpoint Judgment

To find a breakpoint in a wire, trace along the wire with the screwdriver pen. Where the green light is on, the line is continuous. If the light is not on, it indicates a line disconnection point (breakpoint).

Maintenance

• Cleaning: Use a soft, dry cloth to clean the multimeter and screwdriver pen. Do not use abrasive cleaners or solvents.
• Storage: Store the devices in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove batteries from the B05 Screwdriver Electric Pen.
• Battery Care (Multimeter): Recharge the multimeter regularly to maintain battery health. Avoid fully discharging the battery for long periods.
• Battery Care (Screwdriver Pen): Replace LR41 button batteries as needed. Refer to the "B05 Screwdriver Electric Pen Battery Replacement" section for instructions.

Troubleshooting

If you encounter issues with your ANENG multimeter or screwdriver pen, refer to the following common problems and solutions:

• Multimeter Not Powering On:
  • Ensure the battery is charged. Connect the Type-C cable and check for the "CHG" indicator.
  • Long press the power button firmly.
• Inaccurate Readings:
  • Check that the test leads are securely inserted into the correct jacks for the selected measurement.
  • Ensure the correct function is selected for the measurement type (e.g., AC for AC voltage, DC for DC voltage).
  • Verify that the component or circuit being measured is not live when performing resistance, capacitance, or diode tests.
  • For current measurements, ensure the multimeter is connected in series.
• "OL" or "-OL" Display: This indicates an over-range condition. The measured value exceeds the maximum range of the multimeter for the selected function.
• Screwdriver Pen Not Lighting Up:
  • Check and replace the LR41 button batteries if necessary.
  • Ensure your hand is touching the top metal cap for zero live wire determination.
• Multimeter Burn Out Warning:
  • NEVER connect the multimeter directly across a power supply in current measurement mode.
  • NEVER connect the multimeter to the current input jacks when measuring voltage.
