Frequently Asked Questions
Q: What is the difference between the BSIDE S10 and S11 digital multimeter?
A: Both the S10 and S11 share the same core measurement features — 9999 counts, 3.5" backlit LCD, AC/DC voltage, NCV detection, resistance, capacitance, and frequency. The key difference is power: the S10 uses 2×AAA batteries, while the S11 features a built-in 800mAh rechargeable Li-ion battery with a USB charging cable. The S11 also includes a protective shell for added durability.
Q: Does this multimeter measure non-contact voltage (NCV)?
A: Yes. The built-in NCV (Non-Contact Voltage) detection mode allows you to identify live AC voltage without touching the wire or terminal. When voltage is detected, the buzzer sounds and the LCD bar display alerts you in real time — a key safety feature for electricians and DIY users.
Q: What is the voltage measurement range of this digital multimeter?
A: The BSIDE S10/S11 measures DC voltage from 0.8V to 620V and AC voltage from 2.2V to 620V, both with a resolution of 0.001V — making it suitable for everything from low-voltage electronics to standard household and industrial circuits.
Q: Is a battery included with the multimeter?
A: The S10 model requires 2×AAA 1.5V batteries, which are not included. The S11 model includes a built-in rechargeable Li-ion battery (800mAh) and a USB charging cable, so it is ready to charge out of the box.
Q: Is this multimeter suitable as a gift for electricians or hobbyists?
A: Absolutely. The BSIDE S series is designed with a sleek, professional appearance, complete measurement functions, and an easy one-button interface — making it an excellent and practical gift for electricians, electronics enthusiasts, students, and home improvement hobbyists.
