Highlights
✦ FNIRSI DSO-TC3 ingeniously integrates digital oscilloscope, electronic component tester, function signal generator and other functions into one. Equipped with 2.4 Inch TFT display. Built-in rechargeable lithium battery.
✦ DSO-TC3 handheld oscilloscope, 10 MS/s sampling rate, 500 kHz bandwidth. It can be used freely for both periodic analog signals and aperiodic digital signals. Equipped with one-key AUTO, the measured waveform can be displayed without cumbersome adjustment.
✦ DSO-TC3 transistor tester can identify and measure various transistors, including NPN and PNP transistors, N-channel and P-channel field effect transistors etc. Automatic detection of pin definition. Automatically analyze NEC protocol infrared code.
✦ DSO-TC3 transistor tester is suitable for pairing of transistors, identification of mixed surface mount, and preliminary screening of small batch components. "Mos Test" mode can test various types of transistors and test capacitance, resistance etc.
✦ Other functional modes: Including circuit continuity test, 0-40 V input voltage measurement, PWM output, 0-32 V regulated diode measurement, DS18B20 temperature sensor measurement, DHT11 temperature and humidity sensor measurement.
✦ Six waveforms: sine, square, pulse stroke, triangle, ramp and DC.

Very nice device 3 in one. A+++
A
1. Take an electrolytic capacitor (e. g. 100 μF) and test it on the component tester.
2. Connect a low Ohm resistor (5..10 Ohm) in SERIES to the same capacitor and test again.
On my TC3:
220 μF 63 V Samwha SD: 209.2 μF 0.08 Ohm.
The same capacitor + 8.98 Ohm 0.5% resistor: 211.3 μF 1.2 Ohm (!!!). How on Earth?
On an old ATmega based component tester:
The same capacitor itself: 206.1 μF 0.19 Ohm.
With the resistor: 208.0 μF 8.49 Ohm. Slightly low (the correct value should be around 9.1 Ohm), but still reasonably close to truth.
The resistor itself displays 9.0 Ohm on BOTH TC3 and the old tester.

Little Offset from in terms of Ampli & Freq in Generator Mode. Some minor issues in Part -detecting Mode. Scope Mode better than expected ( in terms of 3dB Bandwidth) !
Usable 4 Audio & Test of slow AD / DA systems.
