You know you need this. :D The suspense of sitting on the edge
of your seat, wondering if the loadwheel will make it in time. :D



Yeeeeessss, it's time for another electricity meter Accuracy Test,
and in this one then..... The original-cased Sangamo Weston S200.31.

Characteristics:

Single phase, Two wire. 240v, 50Hz. 80A max, 166.66 revs = kWh.

This test, as like the others, will be performed on-phantom, using
Evolution Three of the Meter Accuracy Testing Board, and it will
also be a 0.1 kWh test. This instrument is a Class-2 instrument,
and we can apply a 2% tolerance to the allowed test.

166.66 divided by 10 = 16.666.

2% tolerance as shown below:

Fastest loadwheel speed........ 16.99932
Ideal loadwheel speed............ 16.666
Slowest loadwheel speed....... 16.33268

I have two of these. Click here to see the other one be tested! :D

This instrument has been tested some time before, but I cannot
seem to find the paperwork for it, so it was most likely a "Quickie
Test".

What we have to take into account here with this instrument, is

that it was most likely tested way before I even had a Meter
Accuracy Testing Board: It would've been a few wires, a testing
instrument, (the SPA 02) plug, socket and a 3kW water heater.

Haha. How times have changed. :D

So, having considered that....... Will it pass?

It's all in the video!

Get ready for the suspense, slap it on fullscreen, pull out your
favourite snack, sit back and enjoy the loadwheel action! :D



Thanks for watching.
