Connecting Test Leads

For voltage, resistance, and continuity measurements, connect the test leads to the corresponding ports on the meter:

• Insert the black test lead into the 'COM' (common) port.
• Insert the red test lead into the 'VΩ' (voltage/resistance) port.

Operating Instructions

General Operation

• Power On/Off: Long press the power button to turn the device on or off.
• Automatic Range: The meter automatically identifies the measurement type (AC/DC voltage, resistance) and selects the appropriate range, eliminating the need for manual dial switching.
• Automatic Shutdown: The device will automatically shut down after 15 minutes of no operation to conserve battery life.
• Low Power Prompt: A low power symbol will be displayed on the LCD when the batteries need to be replaced.
• Flashlight: Press and hold the data hold button to turn on the built-in flashlight for convenient use in dark environments.
• Data Retention (H): Short press the data hold button to freeze the current reading on the display. Press again to release.

Measurement Modes

The ANENG PN129 offers various measurement functions:

1. DC Current Measurement (0A-100A)

To measure DC current, switch to the DC current gear. Use the U-shaped clamp to measure a single strand of the conductor. Ensure the conductor is placed in the center of the clamp to avoid measurement errors. The meter will display the current value.

Figure 5: Measuring automotive DC current using the clamp function.

Figure 6: Important note on current measurement: only measure a single core line. Do not clamp multiple wires or bundled cables as this will result in incorrect readings.

2. AC Current Measurement (0A-100A)

For AC current measurement, the U-shaped jaw allows for non-contact measurement of AC current without needing to break the circuit. Simply clamp the single strand of the AC conductor. The meter will display the AC current value.

Figure 7: Non-contact AC current measurement on a single wire.

3. NCV Voltage Detection

To use the Non-Contact Voltage (NCV) detection feature, press the 'NCV' button. Bring the U-shaped jaw close to the conductor. If AC voltage is detected, the meter will beep and the display will show a visual indication.

4. DC Voltage Measurement (0V-400V, 600V)

Connect the test leads as described in the Setup section. The meter will automatically identify the voltage gear. Touch the test probes to both ends of the DC voltage source (e.g., battery terminals). The display will show the DC voltage, with a "-" sign for negative polarity.

5. AC Voltage Measurement (0V-400V, 600V)

Connect the test leads as described in the Setup section. The meter will automatically identify the voltage gear. Touch the test probes to the AC voltage source (e.g., household outlet). The display will show the AC voltage. The meter supports data retention mode for AC voltage measurements.

6. Resistance Measurement (0Ω-20MΩ)

Connect the test leads as described in the Setup section. The meter will automatically identify the resistance gear. Touch the test probes to both ends of the component to measure its resistance. The display will show the resistance value.

7. Continuity (Buzzer) Test

The meter automatically identifies the buzzer gear. Connect the test probes to the two points you wish to test for continuity. If there is continuity (low resistance), the meter will emit a beep sound, indicating a normal path.

Maintenance

• Cleaning: Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Storage: When not in use for a long time, remove the batteries to prevent battery corrosion and potential damage to internal components. Store the meter in its storage bag in a cool, dry place.
• Test Leads: Regularly inspect the test probes and leads for any damaged insulation or exposed metal. Replace them immediately if any damage is found to ensure personal safety and accurate measurements.

Troubleshooting

If the product is not operating properly, consider the following:

• No Power/Display Issues: Check if the batteries are correctly installed and have sufficient charge. Replace with new AAA batteries if necessary.
• Incorrect Readings: Ensure the test leads are properly connected and not damaged. For current measurements, verify that only a single strand of wire is clamped. For voltage or current measurements where the magnitude is unknown, start with the highest range and gradually reduce it to the appropriate range.
• Overload Indicator ("OL"): If "OL" is displayed, it indicates that the measured value exceeds the current range. For manual ranging, switch to a higher range. In auto-ranging mode, this may indicate a fault or a value beyond the meter's maximum capacity.

For persistent issues, please refer to the Warranty/Support section for further assistance.

Specifications

Usage Precautions

1. Do not touch the probes directly with your hands to avoid electric shock and ensure personal safety during testing.
2. Before use, inspect the test probes to ensure there is no damaged insulation or exposed metal.
3. Do not use the current and voltage ranges interchangeably to prevent damage to the instrument.
4. It is best to remove the batteries when not in use for a long time to prevent battery corrosion of other internal components of the instrument.
5. If you do not know the magnitude of the voltage or current to be measured, start with the highest range and then select the appropriate range based on the measured value.

User Tips

Based on user feedback, here are some helpful tips:

• Always ensure the meter is set to the correct measurement mode or allowed to auto-range for accurate readings.
• When measuring current, remember to clamp only a single conductor. Clamping multiple wires will result in an incorrect zero reading.
• The compact size makes it convenient for carrying and use in tight spaces.
• Utilize the flashlight feature when working in dimly lit environments.
