Parameters Setup for Leak Sensing Cable

Since the electrical parameters of leak sensing cable be varied , the electrical parameters of various leak
sensing cables need to be set in the steps below:

Connect the leak sensing cable to the termination; take measurement of the resistance between the
yellow and black cables with the "ohms range" of multimeter after the connection between lead-out
wire and leak sensing cable.

Enter the length of connected sensing cable into "Length of Sensing Cable", and click "Write" to
set the length of connected sensing line in the LP-LPD module; enter the resistance of sensing
cable determined with a multimeter into "Black-line Resistance of Sensing Cable", and click
"Write".
