Hi,
I’m new to using an oscillioscope and purchased the HPS10 as way to start learning.
I’m a bit confused about the input specifications in the manual. The box cover said “Suitable for measurements on … mains voltage applications”, but the manual says Maximum input voltage 100V peak (AC+DC), 200 V peak-peak (AC only).
I’m trying to diagnose a humming transformer and, I’m told, one of the primary reasons for this is DC on the AC line.
This seemed like a great thing to check out with my new oscillioscope - I was thinking I might be able to see the 120v input power offset by a few volts above or below 0 and thereby confirm that theory.
So, I have 2 questions:
-
Given that the US wall outlet voltages are about 120V, will I be able to check this with the HPS10 without blowing out something in the oscillioscope?
-
Is what I’m trying even a reasonable way to go about this?
Thanks!
Stan
