retained by pressing the ENTER key or may be changed by keying in the new tare
weight value and pressing the ENTER key. You may also store the current gross weight
as the new tare value by simply pressing the GROSS key then pressing the ENTER key.
Once a tare weight has been entered the display will automatically change to the net
weight display mode. NOTE: tare weights equal to or greater than the scale capacity cannot be
entered.
NET KEY
Pressing the NET key will cause the 748 to enter the Net Weight Display mode (
Net
annunciator turned on). If a valid tare weight has not been entered, the 748 will ignore
this command.
PRINT KEY
Pressing this key will initiate the transmission of weight data via the printer output port
unless the continuous data feature of this port was enabled during setup and calibration.
Note that the 748 will not respond to this command unless the weight display is stable
and not less than zero. If displaying gross weight, the only weight printed is gross weight. If
displaying net weight, the gross, tare, and net weights are printed. Pressing this key during
calibration or review will step to the bAUd? prompt.
TIME-DATE KEY
Pressing the TIME-DATE key will display the current time. If the time displayed is correct,
press ENTER to display the date. Note that the time is displayed in a 24 hour format with
12 added to all times after noon, i.e. 3 PM would be 1500. If the time displayed is
incorrect, use the numeric keys to enter the correct time and press the ENTER key to reset the time
and display the date. If the date displayed is correct, press the ENTER key to display the
consecutive number. If the displayed date is incorrect, use the numeric keys to enter the correct
date* and press the ENTER key to display the consecutive number. If the consecutive number
displayed is correct, press the ENTER key to resume normal operation. If the consecutive number
displayed is incorrect, use the numeric keys to enter the correct consecutive number (up to six (6)
digits) and press the ENTER key to resume normal operation.
* Remember to enter the date in the same format (month-day-year or day-month-year) as was
selected by the placement of the DOM/INT jumper on the printed circuit board. In the DOM setting,
the date format is month-day-year.
NOTE: The
Time-Date
annunciator will blink while the 748 is displaying the time or date and the
ID
annunciator will blink while displaying the consecutive number.
BAR KEY
The BAR key is used to control the operation of the 30-element bar graph display. If the
bar graph is currently used to display the preset weight comparator status (
PWC
annunciator turned on), pressing this key will return the bar graph to a weight display
mode
(PWC
annunciator turned off). In this weight display mode, the bar graph presents an analog
representation of a preselected range of weight. If the
PWC
annunciator is off when the BAR key is
pressed, (bar graph displaying weight), the 748 will allow entry of the bar graph start and stop
weights.
Pressing the BAR key with the
PWC
annunciator off will result by showing StArt=. Press the
ENTER key to view the current value of weight where the analog display is to begin. If the weight is
correct, press the ENTER key to save it, otherwise enter the correct start weight using the numeric
keys and press the ENTER key to save the new value. The display will now show StoP= which is
the prompt for the stop weight or the right end of the bar graph display. Press the ENTER key to
display the current value of stop weight. If the weight is correct, press the ENTER key, otherwise use
the numeric keys to enter the new value of stop weights and press the ENTER key. The 748 will now
resume normal operation using the new start and stop weight values for the bar graph display. Note
that when the displayed weight equals the start weight, the left most bar graph element will turn on.
As the weight increases, additional bar graph elements will be turned on until the stop weight is
reached at which time the right most bar graph element will be turned on. Note that the start and
