Several small factory of digital power meter in China, they try to advertise their "High End" model, about compliance to western power efficiency standards.
And they use the description: power meter with 6 Level power efficiency.
For unknown reason, the Chinese marketing selected the American description of power efficiency standards.
And they refer to DoE Level VI regulation within the USA.
Translations:
DoE (Department of Energy)
Level VI (Roman number of 6)
This standard went in to effect in the US February 10 2016
In the world of digital power meter, the above standard, this translates that the meter or power tester, this is able to measure reliably down 0.5 Watt (500 mW).
At the year 2024, the European COC Tier 2 this is more strict, the compatible instrumentation it must be able to measure reliably down to 0.075 Watt ( 75 mW) for PSU at the range of 1 Watt up to 49 Watt (power delivery).
In conclusion, the product designers in China, they need to update their digital power meter product design again, so this to be modernized enough, for a true compatibility with the latest standard.
Personally I do believe that COC Tier 2 this will never be updated again regarding minimum required measuring levels.

I bet my socks, that ITTSB Europe, soon will add in it armory, a digital power meter this be modern enough so to compete with latest standards. 8)

This is the plan, but the road this is full of bumps within mainland China.
Especially if you are after of a modern power meter in hardware, along usable PC software.
And the greater problem than all, this is to get in communication by email, with a brand.

The road this is full of bumbs .. no matter of what you get.
I have not see any one owning Yokogawa, Hioki EE, etc etc, digital power meter, and him be dancing from happiness.
All that maters today, this is to get fresh technology at the true price this be sold in China mainland.

The major issue is just one, every one can manufacture and sale 0.5 Class power meter at economical price.
Yokogawa, Hioki EE, etc etc,... they do not do it.
I just need a basic power meter, this able to measure low power.
They do not care so to deliver such an instrument.
From the other hand, the greatest problem of the Chinese, product documentation this might be 30 lines of text the most.
And the text it might be full of mistakes even if this is written in Chinese.
Because the smart Boss, he used a poorly paid girl to do this job, and no one inspected the outcome. :P
