08486

My new one from upgrading to 400 amp service is all digital too.

At first glance it does appear to be 18586....but there are a couple of signs why it is not.

For instance, since the gauges spin faster to slower from right to left, we know that since the 2nd gauge is an 8, it means the very first (far left) hasnt gotten to 1 just yet.

I'd call it 08487, even though it's not quite there yet.

On a side note, if you have a spinning disc type (like pictured above), and you want to know the actual watts presently being consumed, just multiply the Kh constant by 3600, then divide the result by the number of seconds it takes the disc to make one full revolution. The result is actual watts.

For example, on this meter the Kh is 7.2, X 3600 = 25920. If it takes the disc 3 seconds to make one revolution, 8640 watts is presently being consumed. (25920 divide by 3 = 8640).

This formula works on all disc-type meters, but if there are CTs and/or PTs involved, you'll need to factor in their ratios.

8486

although it looks like the pointer is on a higher number in the first position and the 3rd position, if you look at the digit following each of those, the pointer is just shy of the 0 position. As such, it is like a clock. As the minute hand runs around, although the hour hand may be pointing nearly exactly at a number (e.g. 9), until the minute hand reaches 12, it is still 8:XX. same thing with the meter dials.

I see where you got your info on the watts calcs, MM but here is a question maybe you can answer;

at the top of the dials, it is printed on there:

Rr 13 8/9

any idea what that means, if anything?

Mine says Rr 27 7/9 and is a Schlumberger brand.

just curious.

The Rr stands for Register Ratio.

The disc is connected to a shaft that has a worm gear on it. This worm gear meshes with a wheel-type gear. The Rr number is the number of turns this wheel gear makes in order to turn the first dial one revolution.

The Rr number seems to vary with different manufacturers as well as different styles. It's usually some dumb number too; like 13 8/9 or 11 5/7. Wouldn't something like 8 or 12 or even better 10 make more sense?!??

Another bit of basically useless information, unless you're into testing meters! lol.

Rob

P.S. Stuff like this is absolutely fascinating to me. I just HAVE to know not only how it works, but also why it works.

How about 08486.75 ?

I think it's closer to 8486.625


and why would you round up? the entire accurate reading is based on not rounding up but taking the lesser number. Although there is no dial further that would define the last number as 6 and not 7, continuity of method would cause the last dial to be read as 6.

I voted "none of the above",, I watched that meter for the last hour,, its not moving, it can't be "reading" anything.

You would be billed a 8486.
