Customer Consultation

Hi mr Hantek.
I request for your help.
I damage  my oscilloscope and I looking for a board , attach the photos.

The problem was when i try to measure a signal of a inverter welder machine . Accidentally on the second channel i made a cut short 1000 volts .
The osciloscope turn on normaly but it doesn't measure the second channel osciloscope.

Please , how could i do for buy a new board .??

Attach the photos.

If you can solder, please do the test as follows first.
Please input 1kHz/5V square wave (the specific amplitude can be adjusted according to the actual measurement needs) to two channels, set the oscilloscope voltage/div to 100mV, and set the vertical position to 0. Compare and test the waveform of several points in ch1 and CH2 respectively.

Hi miss Any. I did the test on the board. So , on the first channel in all points , 1 to 6 appear the wave , on the second channel didn't. And the batteries didn't charge, i change the batteries but didn't  charge.

Please check whether the P0 has waveform.
Test the continuity of the relay. The attenuation of oscilloscope probe is set to × 1. When the channel voltage is less than or equal to 200mV, the yellow color relay pin in the figure is on. When the channel voltage is greater than or equal to 500mv, the blue color relay pin in the figure is on. You can compare and test two channels.





The 6 points I mentioned in the second reply have no waveform. Does the oscilloscope show straight line? Or no straight line?

If you need a new board, please contact your seller to deal with.
