Very cool to hear that you are satisfied.

In the meanwhile I got my unit too! It's indeed a very great device. Build quality is superior to the Owon Unit I had before (and returned it because of the annoying humm noise!).
I really like it! Its Firmware is March 2021! v1.17 :-) seems to be brand new.

Fan Noise is audible but its not annoying its relatively quiet :-)

Martin.M:
I have a question:

is there a current offset ?

And review of GPP-4323

Edit:  I like this review  :-+ It makes a pretty good case for the product - Instek should consider jjoonathan‘s feedback on the product features and they should adopt/convey his rationale about the value proposition regarding the multiple PSs + the load function in their marketing
Hydron:
Yes, it does have a small but annoying offsets. While I like mine, I really wish GW Instek would share the calibration procedure so I could try and eliminate them. I've had a poke around in the firmware but am not experienced enough to work out how to access the calibration routine.

Korad provides a front panel calibration procedure - has anyone asked GW Instek if they can provide one?
