3.
Calculate the average location of the 3 tests for Sensor 2 (low value).
Calculate the average location of the 3 tests for Sensor 1 (high value).
4.
For the Sensor 2 start point:
Sensor 2 (low value) - 10 m = Start point of sensing for Sensor 2 (Set Start 2)
Subtract 10 m for the start point service loop.
Subtract 10 m if there is an optional isolation loop, to put the Sensor 2 start point inside the
isolation loop.
5.
Set the value of the Set Start for Sensor 2 to the above result.
•
e.g., average location of 3 tap tests for Sensor 2 = 136 m
subtract 10 m to get back to the start point of Sensor 2
(136 m - 10 m = 126 m)
subtract 10 m for the splice point service loop
(126 m - 10 m = 116 m)
subtract 10 m if there is an optional isolation loop
(116 m - 10 m = 106 m)
the Set Start for Sensor 2 = 106 m
6.
Save the configuration (select the Configure menu > Save Configuration).
7.
For the Sensor 1 end point:
Sensor 1 (high value) + 10 m = End point of sensing for Sensor 1
Add 10 m for the start point service loop.
If there is an optional isolation loop, add 10 m to put the end point inside the isolation loop.
8.
Set the value for Set End for Sensor 1 to the above result.
•
e.g., average location of 3 tap tests for Sensor 1 = 2738 m
add 10 m to get to the end point of Sensor 1
(2738 m + 10 m = 2748 m)
add 10 m for the start point splice loop
(2748 m + 10 m = 2758 m)
add 10 m if there is an isolation loop
(2758 m + 10 m = 2768 m)
the Set End for Sensor 1 = 2768 m)
9.
Save the configuration (select the Configure menu > Save Configuration).
Calibrating the Sensor 2 Offset (Loop configurations)
1.
Refer to
Calibrating the Set Start for Sensor 1 and the Set End for Sensor 2 (Loop
, to determine the Sensor 1 (low value) and Sensor 2 (high value)
results from the tap tests.
2.
Add the Sensor 1 (low value) and Sensor 2 (high value) results to determine the Sensor 2
Offset.
e.g., 134 m + 2734 m = 2868 (Sensor 2 Offset)
3.
Set the Sensor 2 Offset to the above result.
4.
Set the Sensor 2 Scale to -1.
5.
Save the configuration (select the Configure menu > Save Configuration).
