lb/kg KEY - Pressing this key will change the weighing units to the alternate units if
selected during the setup and calibration of the instrument. With pounds displayed (
lb
annunciator turned on) pressing this key will change the weight units to kilograms and
the
kg
annunciator will be turned on. Note that this feature must be enabled during setup of the
748P.
PRESET KEY - This key performs two (2) functions. If the
PWC
annunciator is turned
off when this key is pressed, the bar graph display mode will be changed to show preset
weight comparator status and the
PWC
annunciator will be turned on. If the
PWC
annunciator is turned on when this key is pressed, it will allow the target weights for the
presets to be entered. This display will show PSEtx= where x is the preset number and can range
from 1 to 8 depending on the number of preset weight comparators enabled during setup of the
748P. Press the ENTER key to display the currently stored value of preset weight. If the weight is
correct, press the ENTER key to advance to the Trim value. If the weight is incorrect, use the
numeric keys to enter the correct weight then press the ENTER key to save it and advance to the
Trim value. The display will then show trx= which asks for the trim weight for the corresponding
preset weight comparator. Note that the x in the display refers to the preset weight comparator
number and will vary from 1 to 8. Press ENTER to display the stored value of trim. If the Trim value
is correct, press the ENTER key again to save it. If not, use the numeric keys to enter the correct
Trim value and press ENTER to save it and advance to the next preset weight comparator.
Remember that the trim weight is used to compensate for material in transit and causes the preset
to turn on when the displayed weight equals or exceeds the Preset weight value LESS its
associated Trim weight value. Also remember that the preset is based on the displayed weight which
can be either gross or net weight.
This procedure is repeated for each of the enabled preset weight comparators. During entry of
preset and trim weights, the two bar graph elements corresponding to that preset weight comparator
will flash. After all selected preset weight comparators have been reviewed, the 748P will return to
normal operation. This procedure may be stopped by pressing CLEAR on PSEtx= prompt (i.e.
after setting PSEt3=, press CLEAR to not ask for 4-8).
CLEAR KEY - The CLEAR key is used to clear an incorrect entry from the display. If an
incorrect entry is made, press the CLEAR key and re-enter the correct value. Note that
once the ENTER key has been pressed, the CLEAR key can no longer be used to
correct that particular entry.
ENTER KEY - The ENTER key serves two (2) purposes. First, when reviewing setup
parameters, pressing the ENTER key will cause the current setting of the parameter to
be displayed. Second, the ENTER key is used to signal completion of the entry of data
and causes the 748P to process the data entered.
TRUCK KEY - This key is used by the Truck Storage feature to enter truck ID’s
(identification numbers) and perform other truck storage functions.
DELETE KEY - This key is used by the Truck Storage feature to delete truck ID numbers.
ACCUMULATOR KEY - This key is used to display the contents of the 210 weight
accumulators or the 200 truck accumulators, 8 material accumulators, and total gross
and net weight accumulators.
To access the 200 ID accumulators, you must first disable Truck Storage in the 748P setup
procedure (trSto=no). The truck storage area of memory is now used to store ID numbers and
printed weight accumulators. The first 200 ID numbers entered will be accumulated. Upon entry of
the 201st ID, an error will not be displayed. When this occurs, simply use the ID key to set the ID
before pressing the PRINT key. If only Gross weight is printed, the gross weight is added to the
accumulator or, if the indicator is in the Net mode, the net weight will be added.
