Measure complex circuits instantly with this FNIRSI 3in1 multimeter oscilloscope. Built for fast diagnostics, waveform tracking, and precision testing. Compact enough for any bench.
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.
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.
Engineered for electronics repair and research, this portable bench instrument consolidates metering, scope analysis, and signal synthesis into a single pocket-sized chassis.
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.
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.
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.
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.
Perfect for restoring vintage amplifier boards, debugging microcontroller firmware, verifying sensor interfaces, and powering student laboratory exercises.
Production engineers, certification inspectors, university lab instructors, and dedicated DIY hobbyists who refuse to carry redundant equipment.
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.
