Hello
I immediately point out that I am a layman.
Some basics are more in the field of electrical than electronics.
That's why I can not handle myself alone.
I have assembled DSO138 .... works.
However, I see a problem in detecting tension.
The 1 kHz test signal indicates the following values:
1V x5-2,41V
1V x2-1,69
1V x1-1,61
0.1V x5-1,61
0.1V x2-1,61
0.1V x1-1,61
Acu 1.38V check with multimeter
5x 1V =3.22
5x 0.1V=1.55
2x 1V =2.01
2x 0.1V=1.44
Every manual's voltage points are OK.

Re: problem in detecting tension
I have this problem too, afrer upgrade to the last firmware. I think it is soft bug

Halo
jye1 any help??

Re: problem in detecting tension
0.1V x 2 = 0.2V
Test signal - Vmax: 0.45V, Vmin: -0.41V
Vpp: 0.87V instead of 3.3V

I see that Tech help is helpless.
