SL series (1986 to 1990s)	Back	Up
The SL line was a slight redesign of the S series, and the most noticeable change is the base which was now made of the same material as used on the J5S singlephase meter. (more data on the S to SL transition later) The entire SL line has given way to electronic polyphase versions (the Vectron and Sentinel).	photo to be added later photo to be added later
