The Position Sensor Board contains an Optical Sensor which must be positioned in
the Ratio Beam's center of travel for the balance to function properly.

the Weighing Pan in its normal position. The On/Off switch is the second button

the Position Sensor Board: if it
is too high or too low, the
display indicates Error 8.X.
Move it until the display
indicates other than 8.X.
Then tighten the screws on
the board. (See Figure 3-96.)
