BSIDE S10 Smart Digital Multimeter – 9999 Counts, True RMS, NCV & 3.5″ Color Display

The BSIDE S10 Smart Digital Multimeter is a compact, intelligent measuring instrument featuring a large 3.5-inch color display, 9999-count resolution, automatic measurement recognition, True RMS measurement and non-contact voltage detection.

Its smart automatic mode can identify common measurements such as AC/DC voltage, resistance and continuity, making the meter easy to use for electronics troubleshooting, electrical maintenance, DIY projects and general testing.

The large display can simultaneously show multiple pieces of information, such as the measured voltage, frequency and an analog-style bar graph.

Smart Automatic Measurement

The BSIDE S10 features an intelligent automatic measurement mode that simplifies everyday electrical testing.

Instead of manually selecting multiple ranges, the meter can automatically recognize common measurement types and select the appropriate range.

This makes it particularly convenient for quick troubleshooting and everyday electrical work.

Large 3.5″ Color Display

The large 3.5-inch color EBTN display provides clear and easy-to-read measurement information.

Its multi-information display can show up to three types of information simultaneously, such as:

Main Measurement Value

Frequency Information

Analog-Style Bar Graph

The 9999-count display provides improved reading resolution compared with basic 2000- or 6000-count meters.

True RMS Measurement

The BSIDE S10 supports True RMS AC voltage measurement, providing more meaningful AC voltage readings when measuring compatible non-sinusoidal waveforms compared with basic average-responding meters.

DC & AC Voltage Measurement

The S10 can measure:

DC Voltage: 0.8–620V

AC Voltage: 2.2–620V

Resolution can reach 0.001V depending on the measurement range.

This makes the meter suitable for testing batteries, electronic circuits, power supplies, adapters and compatible electrical systems.

Resistance Measurement

Resistance can be measured from approximately:

1Ω to 60MΩ

This wide range is useful for checking resistors, circuits, wiring and other electronic components.

Capacitance Measurement

The BSIDE S10 can measure capacitance from approximately:

1nF to 99.99mF

This allows testing of a wide range of capacitors used in electronic circuits, power supplies and repair work.

Frequency & Duty Cycle

The meter supports frequency measurement up to approximately:

60kHz

It also supports duty-cycle measurement from:

0.1% to 99.9%

These functions are useful when examining compatible AC and pulsed electrical signals.

Non-Contact Voltage Detection – NCV

The built-in NCV (Non-Contact Voltage) detection function allows the meter to detect the presence of AC electric fields without making direct electrical contact.

When AC voltage is detected, the meter provides an audible warning.

NCV is useful as a preliminary indication of potentially energized wiring, but it should not be used as the sole method of proving that a circuit is safe to touch.

Live Wire Detection

The S10 also includes a live-wire detection function.

When a live conductor is detected, the meter provides an audible alarm together with a visual indication on the display.

Continuity Test

The continuity function helps quickly identify connected or broken electrical paths.

When the measured resistance is below approximately 30Ω, the built-in buzzer sounds.

This is useful for checking:

• Wires
• Cables
• PCB Traces
• Switches
• Connectors
• Fuses

Diode Test

The S10 provides automatic diode identification for compatible diodes with a forward voltage below approximately 3.0V.

This is useful for basic semiconductor testing and electronics troubleshooting.

Built-In Flashlight

An integrated flashlight provides additional visibility when working in dark electrical panels, equipment cabinets or poorly illuminated areas.

AAA Battery Powered

The BSIDE S10 uses 2 × 1.5V AAA batteries.

Unlike the BSIDE S11, the S10 does not use the built-in 800mAh rechargeable lithium battery.

AAA batteries are not included unless otherwise specified.

Applications

Ideal for:

• Electronics Repair
• Electrical Troubleshooting
• Arduino & Robotics Projects
• PCB Testing
• Power Supply Testing
• Battery Testing
• Home Electrical Maintenance
• Educational Laboratories
• DIY Electronics
• Technicians & Hobbyists

Important Note

The BSIDE S10 does not measure AC or DC current (amperage). It is primarily designed for voltage, resistance, capacitance, frequency, duty-cycle, diode, continuity and voltage-detection measurements.

The S10 should also not be confused with the BSIDE S11. The S10 uses 2 × AAA batteries, while the S11 version uses a built-in rechargeable lithium battery.

When working with mains voltage, always use appropriate electrical safety procedures and never rely solely on the NCV function to confirm that a circuit is de-energized.
