Initial Setup
Charging the Battery
The BSIDE S11 Red Multimeter comes with a pre-installed rechargeable lithium-ion battery. Before first use, or when the battery indicator shows low power, charge the device using the provided USB charging cable.
- Connect the small end of the USB charging cable to the charging port on the multimeter.
- Connect the larger end of the USB cable to a standard USB power adapter (not included) or a computer's USB port.
- The charging indicator on the multimeter will illuminate during charging and turn off when fully charged.
Connecting Test Leads
Proper connection of the test leads is crucial for accurate and safe measurements.
- Insert the black test lead into the 'COM' (Common) input jack.
- Insert the red test lead into the 'INPUT' jack for most voltage, resistance, capacitance, frequency, diode, and live check measurements.
- Ensure the leads are firmly seated in their respective jacks.
Operating Modes
The BSIDE S11 Red Multimeter offers various measurement modes. The smart mode simplifies operation by automatically detecting the measurement type. You can also manually select specific functions.
Smart Mode (AUTO)
In Smart Mode, the multimeter automatically identifies the tested parameter (AC/DC voltage, resistance, or continuity) and selects the appropriate range. This is the default and most convenient mode for general use.

Voltage Measurement (DCV / ACV)
To measure voltage, connect the test leads across the component or circuit you wish to measure. The multimeter will automatically detect if it's AC or DC voltage in Smart Mode. For manual selection, press the 'FUNC' button until the desired voltage mode (DCV or ACV) is displayed.
- DC Voltage: 0V-620V ±(0.5%+3)
- AC Voltage: 0V-620V ±(0.5%+5)
Resistance Measurement (Ohm)
To measure resistance, ensure the circuit is de-energized. Connect the test leads across the resistor or component. The multimeter will display the resistance value.
- Resistance Range: 1Ω-999.9Ω ±(2.0%+5), 1kΩ-60MΩ ±(1.0%+3)
Capacitance Measurement
To measure capacitance, ensure the capacitor is fully discharged before connecting the test leads. Connect the leads across the capacitor terminals.
- Capacitance Range: 1nF-999.9nF ±(6.0%+5), 1uF-99.99mF ±(3.0%+3)
Frequency Measurement
The multimeter can measure the frequency of AC signals.
- Frequency Range: 1Hz-1000Hz ±(1.0%+5) (ACV: 2V-10V), 1KHz-60KHz ±(1.0%+5) (ACV: 10V-620V)
Diode Test
Use this mode to test diodes. The multimeter will automatically identify if the diode voltage is less than 3.0V.
Continuity Test
For continuity testing, connect the test leads across the circuit or component. A beeper will sound if the resistance is less than 30Ω, indicating continuity.
V-Alert (Non-Contact Voltage Detection) & Live Check
The V-Alert function allows for non-contact voltage detection, providing a beep alarm. The Live Check function also provides an alarm and displays a stripe on the LCD screen to indicate live wires.

Maintenance
- Cleaning: Use a soft, damp cloth to clean the multimeter's exterior. Do not use abrasive cleaners or solvents.
- Storage: Store the multimeter in its carrying case in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, charge the multimeter regularly and avoid fully discharging it for extended periods. If storing for a long time, charge it periodically.
- Test Leads: Inspect test leads for any signs of damage (cracks, frayed insulation) before each use. Replace damaged leads immediately.
Troubleshooting
- No Power:
- Ensure the battery is charged. Connect the multimeter to the charging cable and allow it to charge.
- Press and hold the power button for a few seconds to ensure it's not just in standby mode.
- Incorrect Readings:
- Check that the test leads are correctly inserted into the appropriate jacks for the measurement type.
- Ensure good contact between the test probes and the circuit/component.
- Verify that the multimeter is in the correct mode (Smart Mode or specific manual mode).
- Display Shows 'OL' (Overload):
- This indicates that the measured value exceeds the selected range. In Smart Mode, the device should auto-range. If manually selected, switch to a higher range.
- For resistance, 'OL' typically means an open circuit.
- No Continuity Beep:
- Ensure the multimeter is in continuity mode.
- Check for a break in the circuit or component being tested.
