Post any questions you may have about our current range of oscilloscopes
Newbie here using PS 4244.
Is it ok to meaure a 230V(Mains) UPS Input with a passive probe (10x) ?
Can it be done if N is floating?
Can it be done if N is at ground potential?
No you cannot use the x10 probe it is not rate for mains voltage. You will need to use a probe that is rated for mains voltage like an isolated probe.
For example the TA041:http://accessories.picotech.com/active- ... robes.html
