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 "
