5. Initial Setup
Battery Charging
The BSIDE S20 comes with a built-in 800mAh rechargeable Li-ion battery. Before first use, or when the battery low indicator appears, charge the device using the provided charging cable.
- Connect the small end of the charging cable to the charging port on the side of the multimeter.
- Connect the other end of the charging cable to a standard USB power adapter (not included) or a computer USB port.
- The charging indicator on the display will show charging status.
- Once fully charged, disconnect the cable.

6.1 General Measurement Modes
Press the power button to turn on the device. The multimeter will typically start in auto-ranging mode. Use the function button (if available) to cycle through specific measurement types if needed.
Figure 6: Three Results Display on Screen
- DC/AC Voltage Measurement: Connect the test leads to the circuit in parallel. The display will show the voltage reading.
- Resistance Measurement: Ensure the circuit is de-energized. Connect the test leads across the component.
- Capacitance Measurement: Ensure the capacitor is discharged before testing. Connect the test leads across the capacitor terminals.
- Frequency Measurement: Connect the test leads to the signal source.
- Diode Test: Connect the red lead to the anode and the black lead to the cathode. The forward voltage drop will be displayed.
- Continuity Test: Connect the test leads across the circuit or component. A buzzer will sound if continuity is detected.
- Firewire Recognize (Live Wire Detection): Use the single probe to detect live wires. Follow safety guidelines.
- Environmental Temperature: The device can display the ambient temperature.
6.2 EMF Detection
The BSIDE S20 features an integrated EMF detector to measure electromagnetic radiation. This function is crucial for identifying potential sources of radiation in your environment.
- Switch the multimeter to EMF detection mode (if not automatically detected).
- Move the device closer to the suspected source of electromagnetic radiation.
- The display will show the EMF level, often with a color analog bar and potentially alarm sounds if high levels are detected.

7. Maintenance
7.1 Cleaning
- Wipe the device with a damp cloth and mild detergent. Do not use abrasives or solvents.
- Ensure the device is completely dry before storage or next use.
7.2 Storage
- Store the multimeter in its protective sleeve and storage pouch when not in use.
- Keep the device in a cool, dry place, away from direct sunlight and extreme temperatures.
- If storing for extended periods, ensure the battery is partially charged (around 50%) and recharge periodically to maintain battery health.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on | Low battery or completely discharged. | Charge the battery using the provided USB cable. |
| No reading or incorrect reading | Incorrect mode selection, faulty test leads, or exceeding input limits. | Verify mode, check test leads for damage, ensure input is within range. |
| EMF detection not working | Not in EMF mode, or no significant EMF source nearby. | Switch to EMF mode. Test near known EMF sources (e.g., Wi-Fi router, microwave). |
| Auto power-off too soon | Normal operation (5-minute inactivity). | Press any button to reactivate the device. |
9. User Tips
- For accurate EMF readings, ensure there are no other strong electromagnetic sources directly next to the multimeter that could interfere with the measurement.
- Always start with the auto-ranging mode for general measurements, as it simplifies operation and reduces the risk of selecting an incorrect range.
- Utilize the Data Hold function when taking measurements in hard-to-reach or poorly lit areas to record the reading before moving the device.
- Keep the protective sleeve on the multimeter during use to prevent accidental damage from drops or impacts.
