Make a quick inspection of functions to ensure the device is working soundly. Please perform following steps:
● Turn on power and access the homepage of the mini oscilloscope.
● Connect the oscilloscope with standard signals (e.g. square wave 20KHz，Vpp=5V), set the switch on
probe tip as 1X, plug oscilloscope probe to the Input Channal.Check whether the measured signal value
is the same as the standard value; it can be calibrated if the margin is small.

To upgrade the firmware of oscilloscope, please carry out the operation below：
● Open web browser to visit www.sainsmart.com, download the newest firmware appropriate to oscilloscope
to your PC.
● Press DSO NOTE II 's Power button “ ” for approximately 4 seconds to enter into DFU firmware
upgrading mode and the indicator light flickers.
● Use USB data cord to connect DSO NOTE II to your PC, and a removable hard disk named
“DFU V3_40_D” will appear on your PC. Copy the hex firmware to the root directory of that disk.
After the extension of the firmware changes from “hex” to “rdy”, restart DSO NOTE II. Then the
upgrading process is finished.
