Features: DSO-TC3 ingeniously integrates digital oscilloscope, electronic component tester, function signal generator and other functions into one-. DSO-TC3 handheld oscilloscope has a real-time sampling rate of 10MS/-s and a 500kHz bandwidth. Can automatically identify and measure various transistors, including NPN- and PNP- transistors, N-channel and P-channel field effect transistors, junction- field effect transistors, diodes, dual-diodes, thyristors, and resistors, inductors, capacitors and other passive components-. Especially suitable for fast- pairing of transistors, identification of mixed surface- mount and wordless components-, and preliminary screening of small batch- components-. Including circuit continuity test, 0~40V input voltage- measurement, PWM- output, 0~32V regulated diode- measurement, temperature sensor measurement, DHT11- temperature and humidity sensor measurement.
