f
If TO1 is missing axles, move the J201 jumper to the next higher sensitivity
position. If it is currently on the highest sensitivity position, call STC for help in fixing
this problem.
g
If TO2 is missing axles, move the J202 jumper to the next higher sensitivity
position. If it is currently on the highest sensitivity position, call STC for help in fixing
this problem.

a
Access the Interface Board as detailed in Step 23.
The available loading sensitivities vary depending on which version of Interface
board you have and whether resistors are attached to the jumpers or not. The
version number is printed on the lower-left edge of the board.

The table below lists the highest, middle, and lowest sensitivity for transducer
loading for current board versions. Highest is the most sensitive. The jumper's top

If TO1 is recording extra axles, move the J201 jumper to the next lower sensitivity
position. If it is currently on the lowest sensitivity position, call STC for help in fixing
this problem.
d
If TO2 is recording extra axles, move the J202 jumper to the next lower sensitivity
position. If it is currently on the lowest sensitivity position, call STC for help in fixing
this problem.
e
Reattach the cover over the Interface board.
