Balance mechanism digital display calibration
The digital display (14) indicates setting of the balance mechanism on a scale of 00 (minimum set-
ting) to HI (maximum setting). In the unlikely event of this system requiring calibration, proceed as
follows:
Level the platform and apply the tilt brake (7).
Turn the balance knob (16) fully clockwise to its maximum stop.
1 Press and hold the switch (13) for approximately eight seconds, until the digital
display shows CA.
2 Release the switch (13). The display shows HI.
3 Ensure balance knob (16) is turned fully clockwise to its maximum stop, then
press and release the switch (13). The display will now show LO.
4 Turn the balance knob (16) fully counter-clockwise to its minimum stop. Press
and release switch (13). If the calibration is successful, the display will now show 00.
5 If unsuccessful, Er will be displayed. Pressing the switch (13) again, or waiting for
15 seconds, will allow the system to revert to its previous settings. Calibration may
now be carried out again.
After calibration, rebalance the head (See Balancing the head).
NOTE: If more than 15 seconds is allowed to elapse between steps, the system will
shut down and revert to its previous settings.
