So that's what "register ratio" means! I was told Rr stood for "register ratio" but that I didn't have to worry about it. I never made the connection. Yes, this information is on all North American meters (that I know of), albeit in cryptic form. Canadian meters are the same as US meters. It's all one market. (Although, according to
www.watthourmeters.com , Canada held on to the single-phase A-base quite awhile longer than we did. Anyone know anything about this?)
Russian meters turn up from time to time on eBay. I've seen them from the '50s to the '90s. The ones from the '50s have the nameplates all in Cyrillic characters and can be difficult for a Westerner to decipher. The ones from the '60s on have the electrical terms in international standards, so the meaning is much clearer. (Everything else is still in Cyrillic.)
These meters have rev/kWh on the dial. North American meters do not. If you know what Kh means, or Rr, you can figure it out. Otherwise, it's a mystery.
