Basic Operation
As shown above, acquire input signals (cycle repeatable) for more than once at a slow sample  
rate, arrange the sample points by the time they appear, then recover waveforms.

System Info Display   the   software   and   hardware   versions,   serial   number   and   some   other 
information about the oscilloscope.  
Update 
Program 
Insert a USB disk with upgrade program and the disk icon at the top left corner is 
highlighted. Press the Update Program button and the Software Upgrade dialog 
pops up. Push F6 to upgrade or push F2 to cancel. 
Save 
Waveform
Insert a USB disk and the disk icon at the top left corner is highlighted. Click on 
this icon and you can see the waveform pause for a while, being saved. You can 
find the saved waveform data under the pic_x_y folder in the USB disk. Here X 
represents how many times the oscilloscope is opened. Each press generates a 
corresponding   folder.   For   example,   press   once   and   a   folder   Pic_1_1   is 
generated; press twice Pic_1_2 are generated.
Self 
Calibration
Press this option and the Self Calibration dialog pops up. Press F6 to perform 
the self calibration. Press F4 to cancel.
Advance Buzzer and time setups
Press this button to see the dialog for buzzer and time setups. Turn the knob V0  
to select buzzer or time (with a black frame). Press V0 and the black frame turn 
to be red. Turn V0 again to set ON/OFF or time. Press V0 again to exit or save 
the setups.  
Self Calibration: The self calibration routine can optimize the precision of the oscilloscope to fit 
the ambient temperature. To maximize the precision, you should perform the self calibration once 
the ambient temperature changes by 5  or more. Follow the instructions on the screen.   ℃
