Description

The FNIRSI DST-210 and DST-201 are handheld 3-in-1 test instruments that combine a True RMS digital multimeter, a digital oscilloscope, and a multi-waveform signal generator in a single battery-powered unit. Function selection is handled via a rotary dial, allowing fast switching between measurement modes without navigating menus. All readings are displayed on a 2.8-inch TFT color screen with adjustable backlight and dual display themes.

The oscilloscope function on the DST-210 provides 48MSa/s sampling and 10MHz analog bandwidth, while the DST-201 provides 5MSa/s and 1MHz bandwidth — both with voltage protection up to 400Vpp using a 10:1 probe. Auto measurement functions cover Vmax, Vmin, Vavg, Vrms, Vpp, frequency, period, and duty cycle. Trigger modes include auto, normal, and single, with adjustable trigger level and support for both rising and falling edge triggering.

The multimeter section covers DC voltage up to 1000V, AC voltage up to 750V, DC and AC current up to 9.999A, resistance up to 19.999 Mohm, capacitance, frequency up to 9.999MHz, temperature from -55 to 1300°C, diode testing, and continuity. A single-probe live wire detection function identifies the live conductor in AC circuits without requiring a neutral reference connection. Recording mode captures measurement curves over time for later analysis, and data hold freezes the display at any point.

The signal generator supports 13 waveform types with adjustable frequency, amplitude from 0.1V to 3.0V, and adjustable duty cycle for square and sawtooth waveforms. The DST-210 extends the signal generator frequency range to 50kHz versus 10kHz on the DST-201. The built-in 3000mAh battery provides up to 15 hours of standby time and charges via USB Type-C.

For electronics repair technicians and engineers in Karachi who work across multiple disciplines — from power supply diagnostics to embedded system debugging — the DST-210 and DST-201 eliminate the need to carry a separate multimeter, oscilloscope, and signal generator to a job site, covering the most common field measurement requirements in one instrument.

Why Choose the FNIRSI DST-210 / DST-201?

A handheld oscilloscope, a True RMS multimeter, and a signal generator each represent a separate equipment cost and a separate item to carry. The DST-201 and DST-210 consolidate all three into one instrument the size of a standard multimeter, at a price point that makes the combination accessible to individual technicians and small workshops rather than only stocked labs. The DST-210’s 10MHz bandwidth and 48MSa/s sampling rate give it practical utility for signal integrity checks on microcontroller circuits, switch-mode power supply diagnostics, and sensor output verification. The live wire detection function and 400Vpp overload protection on the oscilloscope input make it safer to use in real-world AC environments than many entry-level scopes. For repair shops in Karachi handling UPS systems, motor drives, and consumer electronics, this is a practical single-instrument solution for field and bench use.
