Thanks!
I think what is happening here is what is explained in this article -> How accurate is the current monitor on an APC Rack PDU (AP7XXX or AP8XXX)? | FAQs | Schneider Electr...
Refer to this section:
rpdu2g firmware v5.1.2, v5.1.6:
- Phase/Bank/Outlet Current - squelched to 0A under 0.5A.
- Device/Phase/Outlet Power - squelched to 0 watts if corresponding current is squelched.
- Outlet Energy - Will NOT be accumulated if corresponding outlet power/current is squelched.
- Device Energy - Will always accumulate, since the unit does consume a very small amount of energy within the internal circuitry.
I think this is what is going on because it looks like when you are getting a reading, it is at 0.6A and it might be squelching if the power consumption drops below 0.5A, thus that outlet's energy is not accumulated if the A reading is squelched.
In v6 firmware, we changed the squelch which might be beneficial for you since you'll get readings all the way down to 0.3A, rather than only to 0.5A. We only claim accuracy, as stated in the article though, down to 0.5A.
So, you could upgrade your firmware if you wanted to? It is a major firmware upgrade though with lots of changes, a new web UI, etc. If you choose to upgrade, which would be AOS 6.1.3/rpdu2g v6.0.9, I'd suggest just reading through this -> Things To Consider When Upgrading or Downgrading a Network Management Card 2 (NMC2) Device between v...
If you need 0.3A accuracy but really do not want to upgrade to rpdu2g v6.0.9 for a specific reason, let me know and we can explore another option.
