6. The power settings available are AA, BB, CC, and DD
with the KT-200.
NOTE! With both units on the same setting both KT-200
amp. meters should read approximately the

and exchange the cables on one unit. The correct
polarity is achieved by the cable hook-up that pro-
duces the lowest amp. meter reading.
IMPORTANT: Failure to follow above set-up will result
in most current flowing through the ad-
jacent clamps and not the pipe.
