Pressing the ENTER key will confirm that the platform is
empty (except for factory-installed options outside the
Rated Load). The LSS Module will calculate the total of all
load cell readings and ensure that the total is greater than
minimum calibration value, but less than maximum cali-
bration value. If successful, the Analyzer will show the fol-
lowing:

CALIBRATE:
COMPLETE

If the empty platform weight is less than minimum calibra-
tion value, the calibration attempt will be unsuccessful and
the Analyzer will show the following: 

CALIBRATE:
< MIN CAL

If the empty platform weight is greater than maximum cali-
bration value, the calibration attempt will be unsuccessful
and the Analyzer will show the following:

CALIBRATE:
> MAX CAL
