Hello Group,
got some interest in this powermeter made by SANGAMO.Seems to be for single
phase 120 VAC.
The below info was lifted off description.
Can I ask for your input if this represents a correct explanation or ask for
correction please or any other useful hints.
Thanks

Copied from Ebay:

"At the far right side of the white dial a circuitdiagram can be found:Three
independent in series loops @120VAC are input to cumulative record wattage
to a maximum of 3000W total; you can use just one or two or three to the max
of 3kW. In addition to these 3 loops( 6 big Terminals)two more loops(4
smaller terminals)are also present. As far as I understand these can serve
to remotely sense wattage. I never used those in the meter I have for myself
but there are many web(news) groups to get help/info if need be. Trust this
helps you and good bidding "
