4. MEASURING PROCEDURE
4.1. Transmitter & Receiver Operation
1. At one end of the cable, connect one of the transmitter terminals
marked “CH1 to CH16” to each core of the cable under tester. Connect
the “COM”reference lead (black alligator) of the transmitter to a core
which is the only known one.
2. At the other end of the cable, connect the “COM terminal”(black
alligator) of the receiver. When the “input terminal” (red alligator) of
the receiver is successively touched on the cores of the cable under
test, the relevant number of the way is indicated on the display of the
receiver (1-16).
Operation example 1: Cable trace test
Operation example 2: Metal water pipe trace test
CAUTION: Though the units already build in the protection
circuit, do not apply voltage that is over 50V (AC or DCV) to
any alligator clips of the transmitter & receiver. Otherwise
the instruments may be permanently damaged.
