Product description: True RMS multimeter with NCV function - FNIRSI S1
The FNIRSI S1 digital multimeter is designed for quick and safe diagnostics of electrical installations and electronics. The device measures AC and DC voltage, resistance, frequency, and temperature , and also provides a continuity test with an audible signal . True RMS technology ensures reliable results even with irregular waveforms, which is important when working with switched-mode power supplies and controllers. The built-in NCV function with visual and audible indication allows voltage detection without contact with the conductor, while the phase and neutral conductor testing mode facilitates basic installation tests. The multimeter is powered by a 1000 mAh battery charged via USB Type-C , has an auto-off function, and a flashlight , which is useful for measurements in dimly lit areas.
True RMS multimeter with NCV function - FNIRSI S1.
The VA HD color display ensures excellent visibility, even in low light conditions.
Main features of the FNIRSI S1 multimeter
- Large VA HD display : high-contrast color screen for clear reading
- True RMS : more accurate measurements of irregular signals
- Automatic identification : intelligent measurement type recognition and automatic range switching
- NCV : non-contact voltage detection with sound and light indication
- Smart Anti-Burn : protection against overload and burnout in case of incorrect operation
- Data Hold : freezes the result on the screen for convenient reading
- Flashlight : built-in lighting for working in dark places
- 1000 mAh battery : built-in power, charged via USB Type-C
- Phase and neutral test : quick identification of wires in the installation
