2. Safety Information

Always adhere to safety precautions when using the multimeter to prevent electric shock or damage to the instrument. Ensure the test leads are in good condition and correctly connected for the measurement type. Do not exceed the maximum input values specified for each range.

• Do not apply voltage that exceeds the rated voltage, as marked on the meter, between the terminals or between any terminal and earth ground.
• Use caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
• Before changing the function, disconnect the test leads from the circuit under test.
• Do not operate the meter with the case open or if the case is damaged.

3. Setup and Initial Operation

3.1. Battery Installation

The Aneng AN101 typically uses AAA batteries. To install or replace batteries:

1. Ensure the multimeter is turned OFF.
2. Locate the battery compartment on the rear of the device.
3. Open the compartment cover.
4. Insert the batteries, observing correct polarity (+/-).
5. Close the battery compartment cover securely.

3.2. Connecting Test Leads

Connect the red test lead to the "VΩmA" input jack and the black test lead to the "COM" input jack for most measurements. For current measurements exceeding 200mA, refer to the specific current input jack if available on your model.

4. Operating Instructions

4.1. DC Voltage Measurement (V–)

To measure DC voltage:

1. Turn the rotary switch to the "V–" position.
2. Connect the red test lead to the positive (+) side of the circuit and the black test lead to the negative (-) side.
3. Read the voltage value on the display.

4.2. AC Voltage Measurement (V~)

To measure AC voltage:

1. Turn the rotary switch to the "V~" position.
2. Connect the test leads across the AC voltage source.
3. Read the voltage value on the display.

4.3. Resistance Measurement (Ω)

To measure resistance:

1. Ensure the circuit is de-energized before measuring resistance.
2. Turn the rotary switch to the "Ω" position.
3. Connect the test leads across the component to be measured.
4. Read the resistance value on the display.

4.4. Current Measurement (mA– / mA~)

To measure current:

1. Ensure the circuit is de-energized before connecting the multimeter in series.
2. Turn the rotary switch to the "mA–" or "mA~" position as appropriate.
3. Break the circuit and connect the multimeter in series with the load.
4. Apply power to the circuit and read the current value on the display.

4.5. Non-Contact Voltage (NCV) Detection

To use NCV function:

1. Turn the rotary switch to the "NCV" position.
2. Move the top end of the multimeter near the wire or conductor.
3. The meter will indicate the presence of AC voltage with an audible beep and/or visual indicator.

5. Maintenance

5.1. Cleaning

Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Keep the display clean and free from dust.

5.2. Battery Replacement

When the battery indicator appears on the display, replace the batteries as described in Section 3.1. Prompt battery replacement ensures accurate readings and proper device function.

5.3. Fuse Replacement

If the current measurement function fails, the fuse may need replacement. Refer to the device's internal diagram or contact support for fuse specifications and replacement procedures. Always use a fuse with the correct rating.
