INDICATOR FUNCTIONS, Cont.
COUNT
The COUNT indicator shows that the display is in the count mode, and that the value
shown is the count quantity of either the pieces removed from the scale platform (reverse
counting) or the number of pieces added to the scale platform (normal counting). The
count value is determined by dividing the net weight by the average piece weight.
WT/PC (WEIGHT PER PIECE)
The indicator shows that the displayed value is the average weight of a single part (from
a previous sampling operation; or entered via the numeric keypad ). The data display will
show a message in the form PP.PPPP with the lb LED lit, or PP oo.oooo with the lb-oz
LED lit.
GROSS
The GROSS indicator shows that the weight displayed is the gross weight. Gross weight
may be displayed only when the WEIGHT key is pressed and a zero tare weight (or no
tare weight) value is stored. The net weight (used in all sampling and counting functions)
is determined by subtracting the stored tare weight from the gross weight. Note that the
GROSS indicator is only active when the display is in the weight mode as shown by the
illumination of either the lb or lb-oz indicator.
PC/WT
The PC/WT indicator shows that the indicator is displaying the calculated number of
pieces per pound, based on the last sample taken. The data display will show a message
in the form PC/LB XXX.XXX, and is the calculated number of pieces per pound,
calculated as the reciprocal of the WT/PC value.
The SCALE ID character in the display's rightmost character indicates which scale is
operational for weighing, sampling and counting. A "1" indicates the internal scale, and a
"2" indicates an external scale. A "T" indicates that the internal scale is being used in
"TEST" mode (.01 oz divisions).
The message "INSUFFICIENT ADD XXX" when seen during a sampling operation,
indicates that the sample size placed on the scale was insufficient to calculate an
accurate piece weight.
