ANENG Multimeter & Clamp Meter Instruction Manual

1. Product Overview

The ANENG Multimeter and Clamp Meter set provides comprehensive electrical measurement capabilities for professionals, hobbyists, and students. The SZ301 Multimeter offers precise measurements of AC/DC voltage, current, resistance, continuity, diodes, capacitance, and frequency. The PN130 Clamp Meter features a unique U-shaped jaw for non-contact current measurement, along with NCV detection for enhanced safety. Both devices are designed for ease of use, portability, and reliable performance.

2. Safety Information

Always adhere to safety precautions when using electrical testing equipment to prevent electric shock or damage to the device. Read all instructions carefully before operation.

• Do not exceed the maximum input values specified for each measurement range.
• Ensure test leads are in good condition, free from cracks or damage.
• Do not use the device if it appears damaged or is not operating correctly.
• Always disconnect power to the circuit before making resistance, continuity, or diode measurements.
• Use caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC, as these pose a shock hazard.
• Keep fingers behind the finger guards on the test leads during measurements.
• The NCV function is for preliminary detection only; always verify voltage presence with direct contact measurement if safety is critical.

4. Setup

4.1. Battery Installation (SZ301 Multimeter)

1. Locate the battery compartment cover on the back of the SZ301 Multimeter.
2. Use a screwdriver to open the battery compartment.
3. Insert the two AA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
4. Replace the battery compartment cover and secure it with the screw.

4.2. Charging (PN130 Clamp Meter)

The PN130 Clamp Meter features a rechargeable lithium battery. Use a standard Type-C charger (e.g., a phone charger) to charge the device. The charging port is typically located on the side or bottom of the unit.

4.3. Connecting Test Leads (SZ301 Multimeter)

For most measurements, connect the red test lead to the VΩmA+ input jack and the black test lead to the COM (common) input jack. For 10A current measurements, connect the red test lead to the 10A MAX input jack.

5. Operating Instructions

5.1. ANENG SZ301 Multimeter Operation

The SZ301 Multimeter features a rotary dial for selecting measurement functions and a clear LCD display for readings.

Measuring AC/DC Voltage:

1. Turn the rotary dial to the desired ACV (V~) or DCV (V-) range.
2. Connect the red test lead to the VΩmA+ jack and the black test lead to the COM jack.
3. Place the test probes across the circuit or component to be measured.

Measuring Resistance (Ω):

1. Turn the rotary dial to the Ω range.
2. Ensure the circuit is de-energized before measurement.
3. Connect the test probes across the resistor or component.

Continuity Test:

1. Turn the rotary dial to the continuity symbol (speaker icon).
2. Connect the test probes across the circuit or wire. A continuous beep indicates continuity.

Diode Test:

1. Turn the rotary dial to the diode symbol.
2. Connect the red probe to the anode and the black probe to the cathode of the diode. The display will show the forward voltage drop. Reverse the probes to check for open circuit.

5.2. ANENG PN130 Clamp Meter Operation

The PN130 Clamp Meter is designed for non-contact current measurement and features a clear display with various functions.

Measuring AC/DC Current (Clamp):

1. Turn on the PN130 Clamp Meter.
2. Open the U-shaped jaw and clamp it around a single conductor (not a bundle of wires).
3. The current reading will be displayed on the screen.

Non-Contact Voltage (NCV) Detection:

1. Press and hold the SELECT button to activate the NCV function.
2. Bring the clamp head near the wire or circuit you wish to test for voltage.
3. The tester will emit a beep and/or flash an indicator when detecting an electromagnetic field, indicating the presence of AC voltage.

6. Maintenance

• Cleaning: Wipe the device with a dry, clean cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the multimeter and clamp meter in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided storage bag to keep all components organized and protected.
• Battery Care: For the SZ301 Multimeter, remove the AA batteries if the device will not be used for an extended period to prevent leakage. For the PN130 Clamp Meter, ensure it is charged regularly to maintain battery health, especially if stored for long durations.
• Test Leads: Inspect test leads regularly for any signs of damage, such as cracked insulation or exposed wires. Replace damaged leads immediately.

7. Troubleshooting

Common Issues and Solutions:

• Device does not power on: Check battery installation (SZ301) or charge level (PN130). Ensure batteries are correctly inserted and not depleted.
• No reading or 'OL' (Overload) displayed: Ensure the correct measurement function and range are selected. For current measurements with the clamp meter, ensure the jaw is clamped around a single conductor. For voltage/resistance, ensure proper test lead connection and that the circuit is within the device's measurement range.
• Inaccurate readings: Check battery level. Ensure test leads are fully inserted and making good contact. Verify the correct function and range are selected for the measurement. Environmental factors like strong electromagnetic fields can also affect readings.
• Continuity test does not beep: Ensure the circuit is de-energized. Check if the test leads are making proper contact.
