Oscilloscope comes with no ground power cable?

(1/10) > >>

Hi everyone, I am a new forum member here, and I am fairly new to electronics ;)

I bought a Hantek DSO4104B from AliExpress and the scope is great with everything working as expected.

The question I have is that the scope comes with a power cable with no ground (i.e. only 2 pins on the plug for 240v AC). Is this normal and should I use a power cord with proper 3 pins? My understanding is that having only 2 pins on the power plug makes the scope floating which can be a safety risk, after watching Dave's video about how not to destroy your scope...  ;D

Thanks!!

When your wall outlet has ground springs your scope is grounded using the showed connector.

It looks like the ground pin is removable.  I may not be seeing it right (old age) but it looks like there is a ground pin in the package.

This plug has earth connection, actually 2 of those. You on the other side of the earth just don't understand it.

Yep. This type of plug is standard for 230 V equipment almost all over the world, aka "Schuko".

It has earth, both on the side clips as well as in the "hole".
