4. Setup

4.1 Battery Installation

The Aneng M113 Multimeter typically uses AAA batteries. To install or replace batteries:

1. Ensure the multimeter is turned off and test leads are disconnected.
2. Locate the battery compartment cover on the back of the unit.
3. Use a screwdriver (if necessary) to open the cover.
4. Insert new batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Replace the battery compartment cover and secure it.

5. Operating Instructions

Before taking any measurements, ensure the multimeter is powered on by pressing the power button.

5.1 AC/DC Voltage Measurement

This multimeter automatically detects AC or DC voltage. The display will show 'AUTO' for automatic range selection.

1. Insert the black test lead into the 'COM' jack.
2. Insert the red test lead into the 'INPUT' jack.
3. Connect the test probes in parallel to the circuit or component you wish to measure.
4. Read the voltage value on the LCD display. The unit (V, mV) and type (AC/DC) will be indicated.

5.2 Resistance (Ohm) Measurement

The multimeter will automatically select the appropriate resistance range.

1. Ensure the circuit is de-energized before measuring resistance.
2. Insert the black test lead into the 'COM' jack.
3. Insert the red test lead into the 'INPUT' jack.
4. Connect the test probes across the component whose resistance you want to measure.
5. Read the resistance value on the LCD display. The unit (Ω, kΩ, MΩ) will be indicated.

5.3 Non-Contact Voltage (NCV) Detection

The NCV function allows for quick detection of AC voltage without direct contact.

1. Press the 'NCV' button to activate the NCV mode.
2. Move the top end of the multimeter close to the wire or outlet you want to test.
3. If AC voltage is detected, the multimeter will emit an audible beep and the NCV indicator light will illuminate. The intensity of the beeping and light may vary with voltage strength.

5.4 Data Hold Function

To freeze the current reading on the display, press the 'H' (Hold) button. Press it again to release the hold function.

6. Maintenance

Proper maintenance ensures the longevity and accuracy of your multimeter.

• Cleaning: Wipe the case with a damp cloth and mild detergent. Do not use abrasives 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 ensure accurate readings and prevent battery leakage.
• Calibration: For professional use, periodic calibration by a qualified technician is recommended to maintain accuracy.
