3. Product Overview

3.1 ANENG ST181 Digital Clamp Multimeter

The ST181 is a digital clamp multimeter designed for measuring various electrical parameters without interrupting the circuit for current measurements.

Figure 2: Overview of the ANENG ST181 Clamp Meter's measurement capabilities, including AC/DC voltage, AC current, resistance, capacitance, diode, NCV, frequency, and continuity.

Key Features:

• Measures AC/DC Voltage, AC Current, Resistance, Capacitance, Continuity, Diode, and Frequency.
• Non-Contact Voltage (NCV) detection for identifying live wires.
• HD Backlit Display for clear readings in various lighting conditions.
• Clamp jaw design allows measurement of wires up to 36mm (1.42 inches) in diameter.

Figure 3: The ST181 features an HD backlit display for improved visibility of measurements.

Figure 4: The clamp jaw opens up to 36mm (1.42 inches) for non-contact current measurement on various wire sizes.

3.2 ANENG A3012 Circuit Tester

The A3012 functions as a voltage test pen and a socket circuit tester, providing diagnostic capabilities for electrical outlets.

Figure 5: The ANENG A3012 combines the functions of a voltage tester and a socket phase/wiring detector.

Key Features:

• Voltage Test Pen functionality.
• Socket Circuit Tester with LED indicators for wiring status (e.g., Open Ground, Open Neutral, Live/Neutral Reverse).
• Leakage Tester (RCD test) to check for proper circuit breaker function.
• Non-Contact AC Voltage detection.
• Breakpoint Lookup for identifying breaks in live wires.

4. Setup

4.1 Battery Installation

The A3012 Circuit Tester requires AAA batteries for operation. Locate the battery compartment, insert the batteries according to polarity markings, and secure the cover.

4.2 Test Lead Connection (for ST181)

For voltage, resistance, capacitance, diode, and continuity measurements, connect the red test lead to the 'INPUT' terminal and the black test lead to the 'COM' terminal on the ST181 Clamp Meter.

5. Operating Instructions

5.1 Using the ANENG ST181 Clamp Meter

5.1.1 Measuring AC Current

1. Set the function dial to the 'A~' (AC Current) position.
2. Open the clamp jaw and encircle a single conductor (not a bundle of wires).
3. Read the current value on the display. The device can measure up to 400A.

Figure 6: The ST181 Clamp Meter is capable of measuring AC current up to 400A by clamping around a single conductor.

5.1.2 Measuring AC/DC Voltage, Resistance, Capacitance, Diode, Continuity, Frequency

1. Connect test leads as described in Section 4.2.
2. Set the function dial to the desired measurement mode (e.g., V~ for AC Voltage, V- for DC Voltage, Ω for Resistance).
3. Apply the test probes to the circuit or component under test.
4. Read the measurement on the display.

5.1.3 Non-Contact Voltage (NCV) Detection

1. Set the function dial to the 'NCV' position.
2. Bring the top of the clamp meter near a live conductor.
3. The device will indicate the presence of AC voltage through audible beeps and/or visual indicators.

5.2 Using the ANENG A3012 Circuit Tester

5.2.1 Socket Wiring Test

1. Plug the A3012 directly into a standard wall socket.
2. Observe the LED indicators on the device. These lights will illuminate in specific patterns to indicate the wiring status of the socket (e.g., correct, open ground, open neutral, live/neutral reverse).

Figure 7: The A3012 provides real-time feedback on socket wiring status via LED indicators and offers non-contact voltage detection.

5.2.2 Leakage Test (RCD Test)

1. Plug the A3012 into a socket protected by a Residual Current Device (RCD).
2. Press the 'RCD Test' button on the device.
3. A functional RCD should trip, cutting power to the socket. If the RCD does not trip, there may be a fault.

5.2.3 Non-Contact Voltage (NCV) Detection

1. Hold the A3012 near a wire or electrical component.
2. The device will indicate the presence of AC voltage through visual and/or audible alerts.

5.2.4 Breakpoint Lookup

1. Use the A3012 to scan along a live wire.
2. The device will indicate the point where the electrical signal is lost, helping to locate breaks in the wire.

Figure 9: The A3012 can assist in locating breakpoints in live electrical wires by detecting the presence or absence of electricity.

6. Maintenance

• Clean the devices with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Replace batteries promptly when the low battery indicator appears.
• Store the devices in a cool, dry place away from direct sunlight and extreme temperatures.
• Inspect test leads for any damage before each use. Replace if frayed or broken.

7. Troubleshooting

• No Display/Power: Check battery installation and charge level. Replace batteries if necessary.
• Inaccurate Readings: Ensure proper function selection and correct connection of test leads. Verify the circuit is within the device's measurement range.
• A3012 Socket Test Errors: Re-insert the tester firmly into the socket. Ensure the socket itself is properly wired and powered.
• NCV Not Detecting: Ensure the NCV function is selected and the device is brought close enough to a live AC voltage source.
