FNIRSI 3In1 Multimeter Oscilloscope

Measure complex circuits instantly with this FNIRSI 3in1 multimeter oscilloscope. Built for fast diagnostics, waveform tracking, and precision testing. Compact enough for any bench.

Key Features

Compact 2.8-inch TFT color display shows crisp waveforms and instant numeric readouts. A built-in 3000mAh battery delivers up to 15 hours of continuous operation. Type-C charging powers the unit reliably wherever you troubleshoot. Overload protection shields sensitive internal components from sudden spikes.

Product Description

This FNIRSI multifunction tester replaces three separate instruments with one streamlined workflow. You gain immediate access to voltage analysis, waveform recording, and active signal generation without switching hardware. The design prioritizes rapid field deployment alongside rigorous lab standards.

Product Overview

Engineered for electronics repair and research, this portable bench instrument consolidates metering, scope analysis, and signal synthesis into a single pocket-sized chassis.

Key Benefits

Catch intermittent glitches quickly with the waveform freeze function and comprehensive auto measurements. Test fragile components safely using built-in voltage clamping and low battery alerts. Generate stable test patterns across 13 adjustable waveforms to validate circuit responses.

Features

• Dual Bandwidth Modes: Select 1MHz for standard servicing or 10MHz for advanced high-speed signal observation.
• Full Range Metering: Capture DC/AC voltage and current, resistance, capacitance, frequency, and temperature in one interface.
• LIVE Line Detection: Identify energized conductors immediately before manipulating exposed traces.

Specifications

The 2.8-inch screen includes adjustable backlighting for clear visibility in dim workshops. The unit weighs roughly 300 grams and measures 177×87×34 millimeters. Sampling performance reaches 48MSa/s on the DST-210 model, delivering smooth graphical overlays.

What’s Included

• DST-210 Unit: Complete 10MHz oscilloscope assembly with integrated signal generator.
• Connection Gear: Crocodile clip probe, P6100 oscilloscope lead, and dual multimeter test probes.
• Setup Kit: Type-C cable, printed reference guide, and protective cardboard shipping box.

How to Use

Clip the multimeter leads to your circuit nodes and rotate the menu dial to your required parameter. Switch the view to oscilloscope mode, attach the probe across the signal path, and adjust the trigger threshold until the baseline locks steady. Press the HOLD button to store unstable waveforms for closer examination.

Customer Benefits

Reduce bench clutter while accelerating fault isolation through simultaneous data capture. Gain confidence in your measurements with calibrated inputs and transparent live readouts that match industry expectations.

Ideal Uses

Perfect for restoring vintage amplifier boards, debugging microcontroller firmware, verifying sensor interfaces, and powering student laboratory exercises.

Who It’s For

Production engineers, certification inspectors, university lab instructors, and dedicated DIY hobbyists who refuse to carry redundant equipment.

Frequently Asked Questions

Does this device measure temperature directly? Yes, the built-in sensor array records environmental and junction temperatures ranging from -55°C up to 1300°C.

Can I run custom output tests with it? Absolutely. The internal synthesizer produces square, triangle, sawtooth, and sine waves between 0.1V and 3.0V with fully adjustable duty cycles.
