problem with Hantek 2C42
Customer Consultation
I bought a Hantek 2C42 on amazon with the seller ? Direwolf-FR ? .I have a problem with it so I write a mail to Direwolf-FR and they said me to write a mail directly to you. So I explain my problem.When I want to check a Ac V for example (230 volt AC) It’s write OL (Over Limit), it work perfectly with the DC V but not with the AC V.See on the picture : I try to make a update with the software on your website but it’s the same. Thanks for your Help.

Please check if there are burnt components in the marked red box on the motherboard.
If so, please take a picture for me.
if you want me to disassemble the device to access the mother card but my product is still under warranty, can I still do it? thank you
Yes, this does not affect the warranty of your oscilloscope.
Yes there are components burnts, sure the R1 and R15 and maybe other around ?
What can you do ?
Because my oscilloscope is under warranty.
Thanks a lot
From the picture, R14 and R15 should be burned out. Please try to replace the two components.
R15: Resistor-Fixed,1K,1/16W,0.1%,TCR25ppm,R0603
R14: Resistor-Fixed,10K,1/16W,0.1%,TCR25PPM,R0603
I replace the two components and it's work perfectly.
Thanks a lot !
