KEY FUNCTIONS
This section describes the use of each of the keys on the Digital Counting Scale. It will be helpful
to refer to the scale keyboard or Figure No. 6 when reading this section.
ZERO The ZERO key is used to perform a variety of functions depending on the current
mode of operation:
Weight Display Mode (lb or kg annunciator on): Pressing the ZERO key will set
the weight display to zero and turn on the ZERO annunciator if the displayed
weight is within ± 4% of scale capacity.
Count Mode (COUNT annunciator on): Pressing the ZERO key while in the Count
mode will reset the count quantity to zero.
Accumulator Mode (ACCUM annunciator on): Pressing the ZERO key while in the
Accum mode will reset the contents of the currently selected accumulator to zero.
PRINT Pressing the PRINT key will transmit RS-232 data to an optional printer,
recording time, date, weight, piece count and ID or part number. Refer to the
Thermal Label Formats section of this manual and Figure No. 12 for typical print
formats.
SAMPLE The SAMPLE key is used to weigh a known number of pieces to be added 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 through pre-established sample sizes
of 5, 10, 25, 50 and 100 pieces. In this manner sample quantities other than the
first one requested by the scale can be used for counting operations. Sample
quantities may also be entered using the numeric keypad in any quantity desired.
COUNT The COUNT key is pressed after removing or adding the requested sample, and
will place the scale in the COUNT mode and start the counting operation.
ACCUM Pressing the ACCUM key will cause the scale to display the contents of the
accumulator (the number of pieces accumulated since the last time the accumulator
was zeroed) for the currently selected identification (ID) number.
+ (plus) The + (plus) key is used to add the current piece count value to the accumulator of
the currently selected identification (ID) number. The ACCUM annunciator will flash
to indicate the accumulation has taken place.
- (minus) The - (minus) key is used to substract the current piece count value from the
accumulator of the currently selected identification (ID) number. The ACCUM
annunciator will flash to indicate the subtraction has taken place.
ID Pressing the ID key will cause the scale to display the currently selected
identification (ID) number and allow the entry of a new ID number.
LOCAL Pressing this key while displaying any weight information will select the
SCALE instrument platform (LOCAL) for sampling, counting or weighing operations.
