Bray 6A Series Quick Start - Manual (Page 6)

Calibration
Adjust the wheel so that the numeric value in the
top right hand corner of the display is below 6.
If it is difficult to turn the wheel, confirm the
following:
a. The yellow locking wheel under the friction clutch
adjustment wheel is not locked (rotate left)
b. Ensure the friction clutch adjustment wheel is
not near the end of travel at either the high or
low end (if so rotate in the opposite direction to
allow enough rotation to complete a successful
calibration)
Once the down tolerance error has been
corrected, the middle character of the message
line will change to an ‘O’.
Continue with the calibration by pressing the
‘ ‘ button once and releasing.
Step 8: Upon completion of a successful
calibration, the status line will display “FINSH”.
