Fnirsi DSO-TC3 multimeter part tester
Handheld Fnirsi 3in1 - oscilloscope, signal generator and component tester, 2.4 inch screenÂ
Call it a smarty meter - the FNIRSI DSO-TC3 crams a digital oscilloscope, signal generator, universal component tester, voltmeter, temperature sensor reader and IR decoder into one pocket-sized device with a 2.4" display and built-in lithium battery. It comes fully equipped: component measurement leads, a signal generator output cable, and oscilloscope probes (X1, X10) with adapter, all ready to go out of the box.
The oscilloscope handles basic waveform measurements, the generator offers 6 selectable signal shapes with adjustable frequency and amplitude, and the universal tester identifies a huge range of electronic components - automatically detecting pinout and measuring key parameters along the way.
