Yokogawa WT310E single phase power meter 100kHz - All it secrets

[Kiriakos GR]

The long story in short version.

If you do a deep research of what Chinese are using as comparison point, the ones manufacturing low-cost power meter,  they all use Yokogawa WT310E.
Therefore even up to date Yokogawa WT310E this is THE comparison point.

I did additional research about Yokogawa WT310E, I did obtain Yokogawa website member account, and I gained access at Yokogawa documentation and software.
My new discovery ... not every WT310E this is identical to another WT310E.

Any one thinking to get WT310E hes will discover " Yokogawa hardware options selector "  when he will try to receive a quote about a unit.

WT310E harmonics measuring and review option (due Yokogawa software) has the code suffix G5.
In order to connect external current probe (BNC plug) at WT310E, the meter it should include the option XT2 

While WT310E has USB connectivity as standard, even so you are forced to select along RS232 port too.
   
Another option this is AC line power plug,  which the WT310E will come with.

-------------------------------------------------------------------------------------------------

In conclusion,  the best configured for my taste W310E this should include suffix of  -C2-EX2-G5

Now the new question... how much it is priced a WT310E-C2-EX2-G5 this loaded with necessary options for energy measurement,  along harmonics review, along with the convenience using external current probe?

I am about to discover soon this answer.

An second question this is of what happens, when you do buy a used  WT310E and with huge delay you do discover that harmonics option this is missing?
I am well aware that Yokogawa its not that friendly at engaging with consumers and small test labs.
Also the pricing of WT310 related hardware options, this seems as hidden at least due internet based product configuration (options selector).
And neither WT310 annual calibration cost this is known.

In conclusion, if you are thinking to get in marriage with a Yokogawa product, then you better spent a month time for research prior of making any final decision.

PS.
For the ones thinking to be able to produce power analysis reports according to IEC standards,  they will need the PRO software version, which this has a price of it own.
Additionally the external box so to plug in (DUT)  mains cord, this has also a price of it own.

I do comeback one year later at this topic, because they are two details which a potential buyer we should be aware of.

First detail, this is product age, at 8/2015 Yokogawa added WT310E in their portfolio.
We can freely guess that R&D and electronic components selection, they are dated since 2013.
The year 2025, its only few months away, and WT310E age will be ten years old technology.

Second detail, WT310E Sampling rate, approximately 100 kS/s
This is another proof which makes obvious, that WT310E was fastest  back in time, nowadays will be easily challenged by any newcomers competitors.

Within mainland China since 2016, they are three direct competitors of WT310E, with a sampling rate of 250 kS/s and or higher than that.

Yokogawa, had all the time in the world to introduce fresher R&D, at this category of digital power meter for testing systems and or production line inspection.
Yokogawa selected to fall in to a deep sleep for ten long years.

Eventually any freshly developed single phase power meter, this may steal the throne of Yokogawa at this products sector.

My advice at sellers of used equipment, you should deflate immediately used WT310E pricing, and let them go for less.
Within 2025 they are two sources getting ready, so to release more advanced, more faster similar products, at lower retail prices.
