SigGen 3-in-1 Handheld Digital Multimeter with Oscilloscope FNIRSI DST-210

FNIRSI DST-210 SigGen 3-in-1 Handheld Digital Multimeter with Oscilloscope

The FNIRSI DST-210 is a next-generation handheld digital multimeter that combines a true RMS multimeter, a handheld oscilloscope, and a DDS signal generator (SigGen) in a single, portable device. From the outset, it offers what traditional multimeters lack: real-time waveform viewing, precise measurements up to 19,999 counts, data logging, trend analysis, and the ability to actively test systems with a test signal. It's a complete tool for diagnostics, service, and field work.

A real handheld oscilloscope – your signal under complete control

The built-in 10 MHz oscilloscope with a 48 MSa/s sampling rate allows you to observe signals with unprecedented detail in this class. Trigger functions, level control, Auto/Normal/Single modes, and Infinite Afterglow make short glitches, peaks, drops, and jitter immediately visible. This is a huge advantage when diagnosing power supplies, audio, LIN buses, PWM, and automotive electronics.

DDS generator that allows you to actively check your layout

The DST-210 is equipped with a DDS signal generator supporting 13 types of waveforms ( among others . sine, square, sawtooth, half-wave, step). Frequency range 0–50 kHz, amplitude 0.1–3.0 V, and adjustable duty cycle 0–100% allow you to test amplifiers, tune filters, simulate PWM, and check system response without using additional equipment. One tool – complete control over the signal.

True RMS Multimeter – confidence in every measurement

As a full-featured true RMS multimeter, the DST-210 measures AC/DC voltage and current, resistance, capacitance, frequency, temperature, diodes, and continuity. It supports Live/Wire (fast phase wire detection), Data Hold, automatic mode, and intelligent burnout protection. This ensures accurate, stable, and safe measurements – even with distorted waveforms.

Graph instead of guesswork – see how the signal changes over time

Curve Mode and the data logging feature allow you to record and display changes in values over time as a graph. This makes it easy to spot instabilities, fluctuations, voltage drops, or temporary problems. This tool is designed for real-world problems, not laboratory ideals.

Capture a split second and analyze it without rushing with the HOLD button

The Waveform Hold function allows you to freeze the waveform at a key moment, and saving the data allows for later analysis or export. If a fault lasts a fraction of a second, the DST-210 will freeze and display it. Less stress, faster conclusions, more effective repairs.

Readable screen in all conditions

The bright 2.8-inch color TFT display offers two themes: daytime (black on white) and nighttime, making the device easy to read in direct sunlight, at night, or in control cabinets. Large digits, graphs, MIN/MAX, and RMS indicators – everything is visible at a glance.

Power and mobility without compromise

A built-in 3000 mAh battery, charged via USB-C, ensures long operating time and convenient use. Programmable auto-off (15/30/60 min) saves energy, and a durable silicone casing protects the device from impacts and workshop conditions. This equipment is ready for field work.

Well-thought-out 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 provide full control even when wearing work gloves. It's a fusion of classic design and modern electronics.
