Four-Channel AC Current Data Logger 
The  SmartReader  3  data  logger  easily  and  conveniently  records  AC current.
Simply  connect  the  data  logger  to  three  ACR  current  probes  (which  are
clamped around power leads)  and begin recording three-phase systems or
related equipment simultaneously.  The probes allow accurate readings  to  be
taken without interrupting any circuits.  The logger also records ambient tem-
perature.
