The 

SAMPLE

 key is used to weigh a specific number of pieces to be added to

or removed from the scale in preparation for a new counting operation.  The
SAMPLE key is also used to change the sample quantity.  Pressing the
SAMPLE key repeatedly will cause the sample size to step in multiples of 10
from 10 to 250.  In this manner sample quantities other than the first one
requested by the instrument may be used for counting operations.  Sample
quantities may optionally be entered via the numeric keypad in any desired
quantity.  The SAMPLE key may be used to return the display to a sample
display from any weight or count display mode.
