UT81B UNI-T Scopemeter Oscilloscope Digital Multimeter
This scopemeter is a pocket size digital storage oscilloscope fulfills basic electronic engineering requirements. Portable Digital Oscilloscope DIY Kit provides waveform viewing, pocket size and over 2 hours battery operation. This DIY kit is a open source code. The Schematic, PCB layout and program code are free for re-design. It is ideal for production test, research, design and education.
The Pocket Oscilloscope is used mainly applied in the following situations:
* Go on-site repair common electronic equipment (air conditioning or industrial frequency power conversion, AC / DC switching power supply or inverter, elevator and building fire-fighting equipment, industrial control circuit)
* Hardware maintenance or software debugging RS232, RS485, I2C, CAN and other communications interface circuits, LED display and keyboard scan driver circuit, brushless motor drive circuit
* Audio equipment and circuits, electronic toys and remote control model car repair electronic circuits
* School after-school teaching practice and student development of electronic small production
* Need to slow signal changes observed for applications (such as: relay and switch contact bounce, the battery charge and discharge curves, power supply load transient response characteristics of the temperature sensor measurements)
* Supply the electronic circuit (SCR voltage, power factor compensation, electronic energy saving lamps, dysprosium lamp mercury lamp sodium lamp drive circuit xenon lights). As for other issues such as: CPU clock, RAM access, bus and USB or Ethernet signal measurement, high frequency and the video circuitry and the need to use the FFT signal analysis, and so occasions, the scope is not competent. Particularly worth mentioning is that this pocket-sized internal battery-powered oscilloscope can be used, so the field measurement, the ground is completely suspended, can be completely the same as the meter, which measured what point, do not consider the problem of ground isolation.
