Fnirsi SigGen 3-in-1 DST-210 handheld digital multimeter with oscilloscope

FNIRSI DST-210 3-in-1 Handheld Digital Multimeter with Oscilloscope SigGen
The FNIRSI DST-210 is a new generation handheld digital multimeter that combines a True RMS multimeter, handheld oscilloscope, and DDS signal generator (SigGen) in one mobile device. Right from the start, it offers what classic meters lack: real-time waveform view, precise measurements up to 19,999 counts, data logging, trend analysis, and the ability to actively test circuits with a test signal. It is a complete tool for diagnostics, service, and field work.


A true handheld oscilloscope – full signal control
The built-in 10 MHz bandwidth oscilloscope with 48 MSa/s sampling allows you to observe signals with unprecedented detail in this class. Trigger functions, level adjustment, Auto/Normal/Single modes, and Infinite Afterglow make short disturbances, spikes, drops, or jitter immediately visible. This is a huge advantage in diagnosing power supplies, audio, LIN buses, PWM, or automotive electronics.


DDS generator for active circuit testing
The DST-210 is equipped with a DDS signal generator supporting 13 waveform types (including sine, square, saw, half-wave, step). The frequency range of 0–50 kHz, amplitude of 0.1–3.0 V, and adjustable duty cycle of 0–100% allow you to test amplifiers, tune filters, simulate PWM, and check circuit response without additional equipment. One tool – full control over the signal.


True RMS multimeter – confidence in every measurement
As a full-fledged True RMS multimeter, the DST-210 measures AC/DC voltage and current, resistance, capacitance, frequency, temperature, diodes, and circuit continuity. It supports Live/Wire (fast phase wire detection), Data Hold, auto mode, and intelligent burnout protection. The result is accurate, stable, and safe measurements—even with distorted waveforms.


A graph instead of guesswork – see how the signal changes over time
Curve Mode and the data logging function allow you to save and display changes in values over time in the form of a graph. This makes it easy to spot instabilities, fluctuations, voltage drops, or problems that only occur momentarily. This tool is designed for real-world problems, not laboratory ideals.


Capture a fraction of a second and analyze it at your leisure with the HOLD button
The Waveform Hold function allows you to "freeze" the waveform at a key moment, and the data recording allows for later analysis or export. When a fault lasts a fraction of a second, the DST-210 will stop it and show it. Less stress, faster conclusions, more effective repairs.


Easy-to-read screen in all conditions
The bright 2.8-inch TFT color display offers two themes: day mode (black on white) and night mode, so the device remains readable in full sunlight, at night, or in control cabinets. Large digits, graphs, MIN/MAX and RMS indicators—all visible at a glance.


Power and mobility without compromise
The built-in 3000 mAh battery, charged via USB-C, ensures long operating time and convenience of use. Programmable auto-off (15/30/60 min) saves energy, and a sturdy silicone cover protects the device from impacts and workshop conditions. This equipment is ready for field work.


Thoughtful ergonomics and classic operation
The iconic function knob combined with a modern interface makes operation quick and intuitive. Automatic range selection, logical menus, and physical buttons give you full control even when wearing work gloves. It's a combination of classic design and modern electronics.
