a. This disconnects the instrument from the sense and signal load
sensor lines and connects the instrument to an internal resis-
tance. The controller stays in this mode until it is determined if
the weight reading with this resistance pulled in is stable and
repeatable (the input section of the controller is functioning cor-
rectly).
b. Press the Enter button. The controller goes to the REFBOX if
the IT junction box is used. If the IT junction box is not used the
display will read NUMLS# or LSALL.

a. The sense and signal load sensor lines are reconnected in the
controller.
b. Next a switch in the Junction disconnects the IT junction box
from the load sensors and connects a resistance in the junction
box.
c. It stays in this mode until the weight reading with this resistance
pulled in is stable and repeatable (the input section of the con-
troller along with the cable connecting it to the junction box is
functioning correctly).
d. Press the Enter button. The display will read NUMLS# or
LSALL.
e. Number of Load Sensor NUMLS#
