The deadpath in metres or inches must be adjusted and converted to binary numbers before
it can be set i n the 10763A binary DEADPATH switches. Use the following procedure to adjust
and convert the measured deadpath to the switch settings.

Calculate N from this formula: N
=
( x ) ( K ) . ( R )
CLOCK RATIO
where:
N
= number to be converted t o binary
X
=
