   For a small amount, we get an oscilloscope with two probes that can be freely operated outside of a stationary service center. The parameters are sufficient to diagnose a fault at the customer’s end. The advantage is the electrical isolation of the device from the power supply, which significantly reduces the likelihood of ground loop formation during measurements.

   Great screen and easy to use. Nice with a signal generator and oscilloscope built in so it saves a lot of space.

   Was delivered quickly and well packaged. The device looks very high-end and has good quality. Everything was included. I am very satisfied with the device; once you’ve read through everything and tried it out, the operation isn’t that complicated. The calibration of the measuring tips worked well. There are many settings that are really optimal. The device can be used for many things and even on the go. Since it is not connected to the power, you do not need a disconnecting transformer for measuring. Highly recommended. 🙂

   Use it in the range up to 6 MHz, as it works wonderfully. Completely sufficient for hobbyists, if not even recommended!

   Quite an interesting and practical toy with a wide range of features. I think it will be useful in car repair, and not only… The set is complete, even includes a soft case, which is pleasantly surprising.
   Shipment and delivery are prompt. The seller knows his business perfectly.
   Thank you for the quality product and excellent service.

   Works great, with a lot functionality not yet complete tested. Gives advantage to work on main power, because probes are not connected to ground. Note that the voltage factor is only for viewing and does not change input sensity.

   Choice products are delivered quickly.
   I wanted to use an oscilloscope, but even as a multimeter it has quite good accuracy; the DC voltage measurement accuracy is 0.05% at 25,000 counts, and at least 1/100 unit accuracy seems reliable to some extent. I would rather use a multimeter as my main tool.
   A product I’m glad I bought.
   It’s a reliable shop, so I can recommend it.
