## Description

3-in-1 multi-function tester for quick electronics diagnostics, combines digital oscilloscope, LCR and signal generator in one portable device. 2.4 inch color TFT screen for easy reading, rechargeable Li-ion battery for field work, automatic component and transistor measurement and identification, multiple waveforms for testing and troubleshooting.
DSO-TC3 multifunctional tester from FNIRSI, which combines the functions of a digital oscilloscope, electronic component tester, signal generator, continuity tester, voltage tester, temperature and humidity meter, as well as infrared decoding.
It is equipped with a 2.4-inch TFT color screen and a rechargeable battery, offering high portability and multiple practical functions in a single product, making it ideal for both amateurs and professionals.
The DSO-TC3 model is an improved version of the DSO-TC2, offering more accurate and stable detection due to significant upgrades, including increased sampling rate, bandwidth and input voltage range, as well as the addition of additional functions such as capacitor ESR testing and transistor detection.
The tester comes with test leads, USB cable and P6100 BNC probe.
