I need to see what is happening to the power at a large cnc machine. It is runnning off of a generator connected to a motor running off a phase converter. This could be a subject of it's own, in which I haven't formed an exact opinion on yet. ![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
The drives are alarming out and shutting down and the generator growls a bit under quick burst of high loads. I need to see if the voltage, or frequency, or both is dropping.
I'm looking at buying a bitscope so I can capture what ever is happening. I know I need some 100x probes to drop the levels and not blow up the scope. But now I'm thinking that since it's low frequency and need bigger clips anyway. Can I just use a resistor? Or a voltage divider between the clips and connect to the scope?
Thanks

PS nice to meet everyone.
