#186461 - You need to save up for a scope!
Responding to: Kai Klaas's previous message
Kai Klaas said:
Many DVM (digital voltage meter) can measure frequencies. By this you can find out, wether you circuit runs at the proper frequency.

But that only tells you that you have something at that frequency - not what you have at that frequency.

To continue the wood-working analogy, this is like trying to measure the length of a plank by weighing it.
Of course, that can work provided you know that the other dimensions of the plank, its density, etc, are exactly correct - but not otherwise.

In this case, we don't even know that it is a plank!
