4. Operating Instructions
The ANENG PN129 offers various measurement functions. Ensure the test leads are properly connected to the corresponding ports (red to positive, black to common) for voltage, resistance, and continuity measurements.
4.1 DC Current Measurement
The U-shaped jaw allows for non-contact DC current measurement. Current and capacitance gears can be cleared to zero before measurement for accuracy.
- Switch the meter to the DC current gear.
- Use the pliers to clamp around a single strand of the wire you wish to measure.
- Read the DC current value displayed on the screen.

4.2 AC Current Measurement
Similar to DC current, AC current can be measured non-contact using the U-shaped jaw.
- After booting, the meter defaults to AC current measurement.
- Simply clamp the U-shaped jaw around a single live wire to measure AC current.

4.3 NCV (Non-Contact Voltage) Induction
The NCV function allows for quick and safe detection of voltage without direct contact, enhancing user safety.
- Press and hold the SELECT button to choose the NCV function.
- Bring the clamp head close to the wire or circuit you want to test.
- The meter will emit a beep when it detects an electromagnetic field, indicating the presence of voltage.

4.4 DC Voltage Measurement
The meter automatically identifies the voltage gear when test leads are connected.
- Connect the watch pen (test leads) to the corresponding ports on the meter.
- Touch both ends of the battery or DC source with the test leads.
- The meter will display the DC voltage.

4.5 AC Voltage Measurement
The meter automatically identifies the voltage gear for AC voltage measurements.
- Connect the test leads to the meter.
- Insert the test leads into the AC outlet or touch the AC source.
- The meter will display the AC voltage. Household AC voltage is typically around 220V.

4.6 Resistance Measurement
The meter automatically identifies the resistance gear.
- Connect the test leads to the meter.
- Contact both ends of the resistor or circuit component with the test leads.
- The meter will display the resistance value.

4.7 Continuity (Buzzer) Test
The meter automatically identifies the buzzer gear for continuity testing.
- Connect the test leads to the meter.
- Touch the test leads to the two points you want to check for continuity.
- If there is continuity, the meter will issue a beep, indicating normal patency.

5. Maintenance
To ensure the longevity and accuracy of your ANENG PN129 Clamp Meter, follow these maintenance guidelines:
- Cleaning: Wipe the meter with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears to ensure accurate readings and proper operation.
- Avoid Drops: While designed for durability, avoid dropping the meter to prevent internal damage.
6. Troubleshooting
If you encounter issues with your ANENG PN129, consider the following common solutions:
- No Power: Check if the batteries are installed correctly and have sufficient charge. Replace them if necessary.
- Inaccurate Readings: Ensure test leads are properly connected and not damaged. Verify that the correct measurement mode is selected. For current measurements, ensure only a single wire is within the U-shaped jaw.
- No NCV Detection: Confirm the NCV function is activated. Ensure the meter is brought close enough to the voltage source.
- Display Issues: If the display is dim or flickering, replace the batteries.
For persistent issues, contact customer support.
