1. Introduction
The BSIDE ADMS1/ADMS1CL is a compact, dual-mode smart digital multimeter designed for ease of use and versatility. It combines the functions of a voltage detector and a multimeter, making it a convenient tool for various electrical measurements. Its automatic identification feature simplifies operation, allowing the device to detect tested parameters and select the appropriate range.
The ADMS1 model features a traditional LCD display, suitable for outdoor use where sunlight might affect visibility. The ADMS1CL model, on the other hand, is equipped with an EBTN screen, offering superior clarity in indoor or low-light environments.

3. Operating Instructions
3.1 Power On/Off
- Power On: Press the red power button (U) to turn on the device. The meter will display "AUTO" mode, indicating it's ready for automatic parameter identification.
- Power Off: Long press the red power button (U) to turn off the device.
3.2 Automatic Measurement (AUTO Mode)
In AUTO mode, the multimeter automatically identifies and measures AC voltage, DC voltage, or resistance. It also displays the AC signal frequency value when applicable.
- Ensure the test leads are correctly connected (Black to COM, Red to INPUT).
- Place the test leads in parallel across the circuit, power supply, or component to be tested.
- The meter will automatically detect the type of measurement (AC Voltage, DC Voltage, Resistance) and display the result on the screen.
- Observe the analog bar on the display for dynamic changes in the measured value.
Figure 6: Examples of measurements including AC Voltage, DC Voltage, and Resistance.
3.3 Specific Measurement Functions
While in AUTO mode, you can switch to specific functions using the blue button (M) for mode selection or the flashlight button.
- AC Voltage (V~) / DC Voltage (V=): The meter automatically detects and displays AC or DC voltage. Max input 400V.
- Resistance (Ω): Measures resistance up to 10MΩ.
- Frequency (Hz): Measures frequency from 40Hz to 1000Hz.
- Continuity: If the resistance between the test leads is less than 30Ω, the beeper will sound, indicating continuity.
- Non-Contact Voltage (NCV) / Live Wire Detection (V~Alert):
- Bring the non-contact voltage sensor at the top of the meter close to the object being tested (e.g., a power outlet or wire).
- The meter will detect AC voltage in the range of 90V~1000V AC (or 6V~1000V AC for specific modes).
- The voltage signal indicator lights (Green, Yellow, Red) and the buzzer alarm will indicate the strength of the detected voltage:
- Low-range (Green): 1/3 analog bar, slow alarm.
- Mid-range (Yellow): 2/3 analog bar, quick alarm.
- High-range (Red): Full analog bar, very loud alarm.

- Live Wire in Wall Detection:
- Long press the blue button (M) to switch to Live Wire in Wall detection mode.
- Place the non-contact voltage sensor near the wall. The meter can detect hidden live wires up to 5cm deep.
- The closer to the live AC voltage line, the higher the bar value, the more frequent the buzzer alarm, and the voltage signal indicator will light up.

- Flashlight: Short press the blue button (M) to turn the flashlight on or off. This is useful for working in dark environments.

4. Maintenance
- Cleaning: Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace the AAA battery when the low battery indicator appears on the display to ensure accurate readings. Follow the battery installation steps in Section 2.2.
- Storage: Store the multimeter in a cool, dry place away from direct sunlight and extreme temperatures. The recommended storage temperature and humidity are -10~40℃ (-4~140℉) and 45%-80%RH.
- Safety: To avoid electrical shock, always remove test leads before opening the case for battery replacement or any other maintenance.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or dead battery; incorrect battery installation. | Check battery polarity; replace with a new AAA battery. |
| Inaccurate or no readings. | Poor contact with test leads; exceeding measurement range; damaged test leads. | Ensure firm contact; verify the measurement is within the device's specified range (e.g., do not measure voltage above 400V AC/DC); inspect and replace test leads if damaged. |
| "OL" or "-OL" displayed. | Measurement exceeds the meter's maximum range. | This indicates an over-range condition. Ensure the measured value is within the device's limits. |
| NCV/Live Wire detection not working or inconsistent. | Weak signal; interference; incorrect mode. | Ensure the sensor is close to the source; minimize interference from other electrical devices; ensure correct mode is selected (long press blue button for Live Wire in Wall). |
