Definitely petite. As supplied the DSO188 is usable up to 40VAC and the input socket is NOT BNC. To make the O-scope really usable a 10X probe is needed. To do so you will have to order a BNC adapter (#930139) & a 10X probe (#1157645), you will then be able to monitor voltages up to 600VAC. Very handy size & with built-in battery it is a convenient test tool you can actually keep in your pocket. Not for precision work but you can trace signals in audio, video & automobile circuits for troubleshooting. The O-scope is shipped with Chinese instructions, you will have to get Bang Good to E-mail you the English version. All-in-all it's worth the price.

With its dimensions of 57 mm by 34 mm by 11 mm, the DSO188 by Daniu can be called a matchbox oscilloscope. If you think this device is nothing more than a fun but useless toy, you are wrong. You can effectively observe signals up to 100 kHz. Of all the cheaper than fifty euro scoops that we have tested, we are most impressed by this DSO188. Despite the small dimensions, the scope is easy to operate and the oscillogram is easy to interpret. Even with the life of about ninety minutes with one battery charge, you can live well in practice. The only unfortunate thing about this beautiful device is that the DSO188 can not be used to reliably measure the numerical quantities of the input signal. The manufacturer had better omitted this option, because with a measurement function that is 'for reference only' you do not have much in practice.
