from the 1050. The arm assembly is repairable and you
should refer to the A & D Arm Exploded Parts View in
this section, and illustrated parts list in this manual for
individual parts identification.

Caution! The potentiometers in this
machine, unlike potentiometers in other
machines, are a three turn pot. Do not
attempt to turn past the built in stop or you
will destroy the potentiometer.
Note: A bad potentiometer can be detected
by looking at the A/D Arm Calibration screen
where the voltages are displayed. As the pot
is turned the voltage should increase or
decrease steadily. If it skips a range(s), the
potentiometer is defective and should be
replaced.

cedure is included in the section.
