1. Introduction
This manual provides detailed instructions for the safe and effective use of the BSIDE ADMS9 CL NCV Smart Digital Multimeter. This ultra-thin, portable device is designed for measuring AC/DC voltage, resistance, frequency, and features Non-Contact Voltage (NCV) detection and Live Wire detection. Please read this manual thoroughly before operation and retain it for future reference.
2. Safety Information
WARNING: To avoid electric shock or personal injury, please read and understand all safety information before using this product.
- Always ensure the multimeter is in good working condition and free from damage before use.
- Do not apply more than the rated voltage, as marked on the meter, between 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.
- Keep your fingers behind the finger guards on the test probes during measurements.
- Replace the batteries immediately when the low battery indicator appears to ensure accurate readings.
- Do not operate the meter with the case open or the battery cover removed.
- If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

5. Setup
5.1 Battery Installation
The multimeter is powered by two 3V IEC CR2032 batteries. To install or replace batteries:
- Ensure the multimeter is powered off and disconnect any test leads from circuits.
- Locate the battery compartment on the back of the device.
- Use a suitable tool (e.g., a small screwdriver) to open the battery cover.
- Insert two new CR2032 batteries, observing the correct polarity (+/-).
- Securely close the battery cover.

5.2 Connecting Test Leads
The BSIDE ADMS9 CL NCV Multimeter features integrated test probes, eliminating the need for manual connection. Simply ensure the probes are clean and undamaged before use.
6. Operating Instructions
6.1 Power On/Off
Press and hold the power button (U) to turn the multimeter on or off.
6.2 Automatic Measurement Mode (AUTO)
Upon powering on, the multimeter typically defaults to AUTO mode. In this mode, the device automatically identifies and measures AC/DC voltage, resistance, and continuity without manual range selection.
6.3 Non-Contact Voltage (NCV) Detection
To use NCV detection:
- Press the V~Alert button to activate NCV mode.
- Move the top end of the multimeter close to the conductor you wish to test.
- The device will emit an audible beep and the display will show a bar graph indicating the strength of the detected AC voltage.
6.4 Live Wire Detection (LIVE)
To use Live Wire detection:
- Press the LIVE button to activate Live Wire mode.
- Touch the red test probe to the conductor.
- The display will indicate if a live wire is detected.
6.5 Flashlight Function
Press the flashlight button (often integrated with another function button or a dedicated button) to turn the built-in flashlight on or off, aiding visibility in dark environments.
7. Maintenance
7.1 Cleaning
Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is completely dry before use.
7.2 Battery Replacement
Refer to Section 5.1 for instructions on replacing the batteries. Always replace both batteries at the same time with new ones of the same type.
7.3 Storage
If the multimeter is not used for an extended period, remove the batteries to prevent leakage and damage. Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
8. Troubleshooting
- No Display: Check battery installation and ensure batteries are not depleted. Replace if necessary.
- Inaccurate Readings: Ensure test leads are properly connected and undamaged. Verify the correct measurement mode is selected (if not in AUTO mode). Check battery level.
- No NCV/LIVE Detection: Ensure the function is activated. The NCV sensor or probe must be in close proximity to the AC voltage source.
