The FNIRSI-1014D is a very cheap instrument and at this price it gives us much more. An update of firmware required, you have to be in contact with the whatsup FNIRSI Technical support (some delay will be occured because is time of the comapany vacation). There is a difference at voltage measurements (Vpp and Vrms) channel 2 has an error of about 4% at 19 volts AC input voltage, channel 1 of my instrument is ok. The frquency measurement is very accurate. I received it without the EU plug adapter and i asked from Banggood to send me it. Also the photos of the FNIRSI-1014D are streched the real width is more than the heigth, see the attached photos. In any case for that price I recomend it, especially for a begginer.The people of the FNIRSI Technical support and of banggood are the best for the customer service.

Excellent oscilloscope. It came to me seven days ago, and I've been testing it 7 days and it works perfectly, plus it's very portable because if you have a portable power bank, that gives you 5 volts, you can use the oscilloscope for wind or solar installations, or to find faults in a vehicle's electrical system. The product arrived nicely packed and without any hits. It is a very professional oscilloscope and an excellent price, with a very large screen and high resolution.

Excelente osciloscopio. Me llegó hace siete días, y lo he estado probando 7 días y funciona perfectamente, además es muy portátil porque si tienes un "power bank" portátil, que te dé 5 voltios, puedes utilizar el osciloscopio para instalaciones eólicas o de energía solar, o para encontrar fallos del sistema eléctrico de un vehículo. El producto llegó muy bien embalado y sin ningún golpe. Es un osciloscopio muy profesional y un excelente precio, con una pantalla muy grande y alta resolución.

Input 1 is always in DC mode. Switching the TS - AC modes of input 2 vice versa. Photo 2 shows that input 2 does not pass the constant component of the signal, although the DC mode is selected. Photo 3 shows that the signal at input 1 is 2.5 nS behind the signal at input 2, although both inputs are connected together at the output of the signal generator. I would like to be able to adjust the output signal level of the generator, but it is not there.

As has become standard very fast and quality delivery. Oscilloscope came out very well packed, but I give you a big plus! The device works as it should, a very good thing for working in electronics.

Jako se stalo standardem velmi rychlé a kvalitní dodání. Osciloskop došel velmi kvalitně zabalený, zato Vám dávám velké plus! Přístroj funguje jak má, velmi dobrá věc pro práci v elekronice.
