Setup

Battery Installation

The multimeter comes with 2 AAA batteries pre-installed. Ensure they are properly seated before first use.

Connecting Test Leads

Insert the red test lead into the "INPUT" jack (positive) and the black test lead into the "COM" jack (common/negative) on the multimeter. Ensure a secure connection.

Automatic Measurement (Auto-ranging)

The multimeter features an auto-ranging function, automatically identifying and measuring AC/DC voltage, resistance, and other parameters without manual range selection.

AC Voltage Measurement

To measure AC voltage, insert the test leads into the live and neutral points of the AC source. The multimeter will automatically detect and display the AC voltage.

DC Voltage Measurement

For DC voltage measurement, connect the test leads across the positive and negative terminals of the DC source. The multimeter will automatically identify and display the DC voltage.

Resistance Measurement

To measure resistance, ensure the circuit is de-energized. Touch the test leads to both ends of the resistor. The multimeter will display the resistance value.

Continuity Test

For continuity testing, touch the test leads to both ends of the circuit or wire. A continuous "dididi" beep indicates continuity.

Diode Measurement

When measuring diodes, ensure the positive and negative poles of the test leads are aligned with the diode's polarity for accurate readings.

Capacitance Measurement

Safety Note:

For safety, always discharge capacitors before attempting to measure their capacitance.

After discharging, touch the test leads to both ends of the capacitor. The multimeter will display the capacitance value.

Millivolt Measurement

When measuring millivolts, the displayed value can be reset to zero before taking a new measurement for precision.

Live Wire / Zero Wire Identification

The multimeter can identify live and neutral wires. When measuring a live wire, the screen will turn red and beep. The neutral wire will not trigger a beep.

AC Current Measurement

For AC current measurement, the test lead needs to be inserted into the 10A jack. Ensure the circuit is properly configured for current measurement (in series).

DC Current Measurement

To measure DC current, connect the multimeter in series with the circuit. The multimeter will display the current flowing through the circuit.

Temperature Measurement

Plug the temperature probe into the designated jacks. Use the probe to measure the temperature of an object.

NCV (Non-Contact Voltage) Induction

The NCV feature allows for non-contact detection of AC voltage. When voltage is detected, the screen will turn red and display "EF" (Electric Field), and the device will beep.

Troubleshooting

If the multimeter is not functioning as expected, consider the following common issues:

• No Display/Power On: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary.
• Inaccurate Readings: Ensure test leads are properly connected to the correct input jacks for the measurement type. Verify the probes are making good contact with the circuit.
• No Continuity Beep: Confirm the multimeter is set to continuity mode. Check for open circuits or damaged wires.
• "OL" (Overload) Display: This indicates the measured value is outside the multimeter's range for the selected function. Ensure you are using the correct measurement mode and range (if not auto-ranging).
• NCV Not Responding: Ensure the NCV sensor is positioned close enough to the AC voltage source.

For persistent issues, refer to the detailed instruction manual included with your product or contact ANENG customer support.

Maintenance

To ensure the longevity and accuracy of your ANENG Digital Multimeter, follow these maintenance guidelines:

• Cleaning: Wipe the multimeter with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the multimeter in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Replacement: Replace batteries promptly when the low battery indicator appears to prevent inaccurate readings and potential damage.
• Test Leads: Inspect test leads regularly for any signs of wear, cuts, or damage. Replace damaged leads immediately to ensure safety and accurate measurements.
• Protective Cover: The silicone cover provides protection against drops and electric shocks. Ensure it is properly fitted.
