modes, SCALE SELECT is used to select from the various options available for
each parameter. (See "Parameter Setup" and "Calibration" for details).
COUNT:
The COUNT key is used to enter the piece count mode in the XC780.
There are several ways to use this key to count parts:
1) Variable sampling - While in the weight mode, entering the
number of samples followed by pressing the COUNT key
samples that number of parts.
2) Fixed sampling - Pressing the COUNT key alone samples the
number of parts set with the "SAMP " parameter.
3) Sample enhancement - While in the count mode, pressing the
COUNT key activates manual sample enhancement.
4) Reverse sampling - With a full load of parts on the scale,
press the COUNT key to initialize the reverse sampling
feature.
Please see the section on "Operation" for complete instructions.
SHIFT/COUNT:
The SHIFT/COUNT combination is used when operating the reverse
sample feature of the XC780. See "Piece Counting Operation/Reverse Sampling"
for details.
APW:
The APW key is used to enter a known Average Piece
Weight(APW) for counting or for displaying the current APW. The APW key is
operated by pressing the APW/STORE key without shift being activated. Enter
the Average Piece Weight on the numeric keyboard(be sure to use sufficient
precision) and press the APW key. The XC780 will store the entered APW as the
current APW and switch to the count mode. Once in the count mode, pressing the
APW key without entering data displays the currently entered Average Piece
Weight.
STORE:
The STORE key is used to enter ID, APW, and tare information into
the XC780 memory for recall later. The STORE key is operated by first pressing
the SHIFT key, then the APW|STORE key. After counting a part, simply enter the
numeric ID you would like to use on the keypad and press SHIFT followed by the
APW|STORE key. For complete instructions see the section on "Piece Counting
Operation" and "ID/Accumulation" in the XC780 Technical Manual.
ID:
The ID key is used to make a new ID the current ID. After
storing piece count information with the STORE key, the ID key is used to
recall the quantity, APW, and tare information to be used in counting parts.
The ID recall is performed by entering the ID number of the part whose piece
count information you wish to retrieve on the numeric keypad and pressing the
ID key. The quantity, and/or APW and/or tare for that ID will now be the
current APW and/or tare used by the XC780 for counting and accumulation. The
ID may be reset to the default value of zero, by entering 0 for the ID. See
the section on "ID/Accumulation" in the XC780 Technical Manual for more
details.
SHIFT:
The SHIFT key is used to activate the second function on all dual
function keys. Pressing the SHIFT key enters the shift mode(the shift light
