Digital Multimeter FNIRSI S1
Overview
Description
FNIRSI S1 is a digital True RMS multimeter featuring a large, high-contrast 9999-digit display and an analog bar graph for swift readings. With its user-friendly design, the instrument is equipped with three buttons for selecting different measurement modes. The model is designed to measure resistance, voltage, frequency up to 4 MHz, capacitor capacitance, temperature, circuit continuity, non-contact voltage measurement in NCV mode, live wire, and more. All measurements can be conducted in both manual and automatic modes.
Powered by a built-in 1000 mAh battery, the multimeter utilizes a Type-C connector for charging. Its exterior resembles that of a smartphone, offering comfortable handling and intuitive button access. Additionally, a small flashlight on the front enables operation in low-light conditions.
Control is carried out using the three buttons below the display:
- Left button (Live/NCV) to select the high voltage and phase non-contact test mode.
- Middle button (SEL) to select manual mode of operation.
- Right button (HOLD) to turn on the flashlight and lock the readings on the screen.
Features
- NVC with sound and light indication
- Type-C charging connector ensuring long-lasting performance from the built-in 1000 mAh lithium battery
- Full overload protection to prevent failures resulting from improper use
- CCAT III 1000V overvoltage standard compliance
- Smart chip for rapid and precise true value and automatic measurements
- Data hold function
- Low battery indication
- Auto power off function
- Built-in flashlight
- Suitable for various applications such as checking household outlets, fuses, batteries (including car batteries), troubleshooting car circuits, testing charging systems, and examining car electronics
