Additional CT (current transformer) clamp for the Current Cost CC128 Envi monitor.

Also compatible with the original Current Cost 'Classic'.  The Current Cost transmitter unit can accept up to three CT clamps for use with Economy 7 or three phase supplies.  When additional CT clamps are connected to the transmitter, the '2' and/or '3' icons in the upper right hand corner of the display unit will be activated. 

The calculated values on the CC128 display unit will be the sum of all connected CT clamps, although PC users may be able to study the data from each sensor individually, depending on the software used.
