Quick start instructions

 

2.1

 

Power

 

Press and hold the power button on/off. 
When  the battery  is  dead,  use  the  USB  cable  to  connect  to  the  5V  adapter  for 

charging,  and  the  charging  current  is  about  700mA.  It  is  best  to  use  a  computer  or 
mobile  phone  for  charging.  The  LED  lights  up  red  when  charging,  and  turns  green 
when fully charged. 

2.2

 

Auto 

After  the  probe  is  connected  to  the  signal,  press  the  [Auto]  button,  and  the 

oscilloscope  will  automatically  detect  the  signal  and  adjust  the  range.  If  there  is  no 
waveform, the probe may not be connected correctly, or there may be no signal at the 
connection (you can use a multimeter to determine if there is a voltage). 

2.3

 

Sensitivity and time base 

Manual adjustment: “mV”/ “V” buttons scale the waveform vertically. The “s”/ 

“ns” button scales the waveform horizontally. 

The  vertical  sensitivity  indicates  the  voltage  of  a  grid  in  the  vertical  direction, 

and it is adjusted by the mV and V buttons to adapt to different voltages. 

The time base represents the time of a grid horizontally. It is adjusted by the S 

and NS buttons to accommodate different frequencies. 

2.4

 

Test built-in signal generator 

1. Connect the probe to the generator output pin. 2. Press the [Gen] key to open 

the generator interface, and then press the [Stop] key to change the generator to the 
[ON] state. Press the [ns] key to switch waveforms. Press the [Single] key to reset to 
1.00Khz. 3. Press [OK] to exit the interface. 

4. After pressing the [Auto] key, you can see the waveform of the generator. 

 

2.5

 

Use of Multimeters 

Check  the  red  pen  first  in  the  voltage  hole.  Press  the  [Select]  key  to  open  the
