Operation guide
Operating area
In the red area in the figure, slide up and down with a single finger, and the
operability icon is C1, C2, V1 In the blue area in the figure, slide up and
down with a single finger, and the operability icon is T/C1, V2 Select the
icon you want to slide to turn it blue (active), and slide your finger up and
down anywhere in the corresponding operation area to move the icon. The icon
will move with the speed of the finger.
Swipe left and right with one finger in the red area in the picture, and the operability icon is T (Icon in red circle) S1,S2 Select the icon you want to slide to turn it blue (active), and slide your finger up and down anywhere in the corresponding operation area to move the icon. The icon will move with the speed of the finger.
Multi-point gesture operation
This machine supports 2-point gesture operation and 3-point touch screen capture.
Two-point gesture operation
When the C1 or C2 channel is selected and the red circle turns blue, the two-
point touch will take effect for that channel.
(Portrait) Two-point touch you can change the magnification of the waveform
(that is, change the voltage gear)
(Horizontal) Two-point touch the time base of the waveform can be changed (the value in the red circle in the figure)
Three-point gesture operation
After inserting the U disk, at any position on the screen, tap three fingers at the same time for 1 second after the buzzer sounds, a progress bar will appear, and the screenshot will be completed after the progress bar runs through the buzzer prompt.
Interface description
Boot into the main interface:
The main interface can choose oscilloscope, signal generator and setting
interface.
Click settings to see Language selection, sound switch, brightness adjustment
and software and hardware version number. You can modify it as needed. Click
on the oscilloscope to enter the oscilloscope
interface:
Click on the signal generator to enter the signal generator interface:
Oscilloscope instructions
STOP key
Press stop to stop the waveform, and the stopped waveform can be zoomed in and
out to view the details. There is a small image of the original waveform in
the upper left corner.
Trigger option key
Click the red circle T/C1 button, and the trigger option will pop up
- Can choose
- Signal source C1 or C2
- Rising edge or falling edge
- Auto trigger, normal trigger and single trigger
- Smart trigger or manual trigger
- Note: There is no need to manually adjust the trigger position of the waveform under smart trigger, the program will automatically find the appropriate trigger position and trigger the waveform.
Time base button
The button in the red circle in the picture is to reduce the time base, and the button in the basket is to zoom in the time base, while the button in the yellow circle displays the current time base value, the time position (that is, the parameter in the white circle) can be returned to zero with one key.
Oscilloscope-signal generator switch button
This switch key can switch between oscilloscope and signal generator with one key.
menu
Mathematical calculation
In this interface, you can choose to turn on or off the display of
mathematical calculations, and you can choose YT or XY (Li Shayu) display
mode
Ruler menu
The horizontal and vertical rulers can be opened in this interface. As shown in the figure, the movements and selections marked follow the operation guide. The signal source for simultaneous calculation can be C1 or C2
Parameter display
After opening the parameter display, you can select the parameter to be displayed by the corresponding channel, and the parameter will be displayed at the bottom of the screen.
Function options
Store waveform
- After clicking to store the waveform, the current waveform will automatically stop and enter the stop state.
- In this interface, you can choose to save or read the waveform data of the previous waveform.
- The read waveform data can be arbitrarily zoomed in and out to view the details, which is equivalent to the stop state.
Automatic calibration
This button will automatically calibrate the oscilloscope parameters.
Warning! Do not operate the device during automatic calibration, and do
not connect any external connectors!
Restore Factory
This button will return the machine’s settings and some parameters to the factory state.
Set up
Equivalent to the settings of the main interface
return
Can return to the main interface under the oscilloscope interface.
C1Channel menu
In this interface, you can zoom in and out the waveform voltage range of C1,
You can choose whether to display the C1 waveform Select the X multiple of the
probe
Choose AC, DC Select whether the display of C1 waveform is inverted The
vertical position of C1 can be returned to zero with one key The red circle in
the picture can select the C1 channel, and the basket ring can quickly open or
close the C1 channel
C2Channel menu
- In this interface, you can zoom in and out the waveform voltage range of C2,
- You can choose whether to display the C2 waveform
- Select the X multiple of the probe
- Choose AC, DC
- Select whether the display of C2 waveform is inverted
- The vertical position of C2 can be returned to zero with one key
- The red circle in the picture can select the C2 channel, and the basket ring can quickly open or close the C2 channel
Signal generator instructions
- Through the corresponding +,- to modify the frequency, amplitude, offset, duty cycle and other signals, the waveform will be directly changed in real time.
- The red circle area can select the waveform to be output.
Screenshot
After inserting the U disk, at any position on the screen, tap three fingers at the same time for 1 second after the buzzer sounds, a progress bar will appear, and the screenshot will be completed after the progress bar runs through the buzzer prompt.
Program upgrade
When the machine is turned on, insert the U disk containing the upgrade file,
and then power on, the device will automatically enter the U disk upgrade
program, click the upgrade button in the upgrade program, wait for the upgrade
progress to 100% and automatically shut down.
Warning! Make sure that the battery level of the device is in the green mode
when upgrading!!
