5. Weight Bar Operation
The weight bars indicate the direction required to rotate the wheel to bring the weight application
position to the correct place for weight application.
If there are no results displayed the bars rotate with the wheel (after encoder initialisation) but the green
application led is never displayed.
If static mode is active only the left bar is displayed.
If results are available and the result for each plane is greater than the threshold (see fine mode below),
the green application led of the relevant bar is lit and all bar leds are lit when the wheel is at the correct
position for application ( +/- 1.4 degrees).
The correct position for application is 12 o'clock - C88 offset for non-hwm modes and 12
o'clock + gauge arm offset for stick on weights in hwm modes.
During SWM mode when results are displayed, the result magnitude shown for the right or
outside correction plane is that closest to the application position (see below).
6. Sape Operation
High Level Functionality
The sape can be used for both data entry and weight application.
During a non-hwm weight application mode (anything but hwm1 and hwm2) removing the sape from the
home position causes any results displayed to be removed from the display.
If the sape is removed while in manual data entry mode the data entry function is first exited (see above)
and then the sape becomes functional as detailed below.
If the sape is removed while a measuring run is in progress the run will be terminated, a
beep will sound, the wheel will be braked and "E10" is displayed. After 7 seconds E10 is
cleared.
If an attempt is made to use the sape while in another mode of operation (service menu, user
management, star menu, etc...) the sape does not interrupt the function in use and cannot be used.
When the function is exited by the user the sape becomes active if it is not at the home position.
If we are in HWM mode 1 or 2 there are two modes of sape operation, data entry and weight
application.
Data entry is the default mode of operation when hwm1 is entered. When valid results are
made available (see recalculation above) weight application is enabled. Weight application is
disabled by pressing the "offset" key with the sape in the home position. A beep is
generated.
