Hello everyone,
I have a problem with Keithley 2015 THD. On the first output of the generator, I do not have a sinusoidal signal, but on the second channel I have both a sinusoidal signal and pulse (of course, switched not at one time). What could be the cause of the fault? Is there any service documentation with diagrams of this meter available? Where and what should I measure?
I bought this meter as used. I wonder if by connecting a signal from the generator to the tested equipment and at the same time having a connected oscilloscope, with a short circuit with a PE wire, it can work correctly? Could such damage occur as a result of a short -circuit of the negative potential of the generator with the Protective Power of the PE? The easiest way to write a question is: can the generator output sockets be connected directly to the PE protective cable? Because I noticed that they are factory isolated from the metal parts of the meter housing and probably for a specific reason.
I want to measure the harmonic distortions of the audio amplifier channel with this device. So I want it to work in the loop without using an external generator, because I think that the internal generator will be the most precise and most tolerated, thanks to what the meter.
What is your opinion on this matter? How is it best to measure audio signal distortion with this meter?
