No test signal

Post by Yeti »

Greetings from Germany.
My problem: I don't have a test signal
First of all, here are my voltages:

Code: Select all

V+   8,36V
AV+  6,68V
V-  -7,43V
AV- -5,79V
V1   2,5mV
V2   0V
V3   2mV
V4   1,52V
V5  -1,02V
I think this is ok?
When I try to calibrate the DSO I don't have a signal. Not at 0,1V nor at 3,3V.
Ok, there is something that "could" be a signal but at around 1mV at 3,3V setting.
I followed the FAQ and get a reaction if I touch the red clip. I can also see the signal of an Mp3 Player and get the correct Voltage of a 9V battery.
Also I have 1,6V DC on my multimeter when measuring the test signal terminal and it's raising to 3,2V when switching from GND to DC or AC and it remains stable when connecting the BNC clip.

Any suggestions ?
Thanks in advance
