This product adopts ultrasonic principle to take meas-
urement of cable height. When taking measurement, the
unit transmits an ultrasonic signal by a 15 angle to tow-
ards the wires and measuring the time it takes to pick up
the echo from the signal.
This unit takes conveniently, operates easily, circuit
maintainer can make measurement of cable height and
wire to wire distance at any time anywhere, which not
need to get in touch with electric (communicating) high
cable.
