Just an FYI, a re-occurrence of a previous observation from a few years back, it concerned loosing time on some devices while running from "some" Inverters.
We have a large late model Sharp Microwave, it's used for thawing pet food. I don't like microwaves for a number of reasons but that's a different story.
This Microwave has a clock that is obviously synced to the mains frequency. Some inverters cause it run slow after a few days. The last EG8010 inverter kept time, some previous inverters also based on the EG8010 did not.
The Nano AC frequency can be set to 49.939Hz or 50.002Hz. It was set to the lower, and causes the microwave to loose time.
Note, the accuracy of these readings may be influenced by noise.
The measured AC mains frequency is slowly varying between 49.993Hz and 50.022Hz.
Changing the Nano to 50.002Hz, which measures 50.013Hz AC, should allow the microwave to keep better time.
I'm pleased to say that I've had no lost or gained time over the past few days.
EDIT: Download link in previous post now v6.50, has an freq option in full menu.
