The FNIRSI DST-210 is a next-generation portable digital multimeter that combines a True RMS multimeter, a portable oscilloscope, and a DDS (SigGen) signal generator in one handheld device. It offers:

• Real-time waveform display.
• Accurate measurements up to 19,999.
• Data logging and trend analysis.
• Active circuit testing with signal output.

The built-in oscilloscope features a bandwidth of 10 MHz with 48 MSa/s sampling rate, enabling detailed signal observation. It provides triggering functions, level adjustment, and other settings for optimal diagnostics. The DDS signal generator supports 13 waveform types and offers a frequency range of 0–50 kHz with adjustable amplitude, suitable for circuit testing.

As a full RMS multimeter, the DST-210 measures AC/DC voltage and current, resistance, capacitance, frequency, temperature, diodes, and circuit continuity. It features Live/Wire phase detection, Data Hold, and intelligent burn-out protection.

The Curve Mode function allows storage and display of value changes over time. The DST-210 features a bright 2.8-inch color TFT display with accessible and easy-to-read indications in any lighting condition.

The built-in 3000 mAh battery is charged via USB-C, ensuring long operating time and ease of use. The durable silicone cover protects the device from impacts.

Ergonomic design and modern interface make usage easy, providing full control to the user.
