Salter Brecknell 7840 - Manual (Page 23)

Model 7800 Family Weight Classifiers User’s Manual 23
The 78XX provides three options for transmitting
displayed weight without requiring a remote
device to initiate the request for weight to the
scale. These options are selectable in the CONF
setup menu PROT and are as follows:
Weight is automatically transmitted after weight
is removed from the scale platform. The last
“stable” weight prior to removing the item will be
“sent,” as soon as the displayed weight returns to
within five display divisions (i.e. 5d). This option
is normally used in applications where items are
added to a box already placed on the scale, but
where only one weight data transaction is to
occur. See note at left.
Weight is automatically transmitted when the
item is placed on the scale and the weight
stabilizes. This option is normally used in an
application where the item placed on the scale is
sealed and ready for the shipment weight to be
registered. The minimum stable weight required
to trigger an auto SEND is set at five display
divisions (i.e. 5d).
Weight is transmitted only when the TEST button
on the display panel is pressed. The TEST button
is redefined as a SEND key when in the normal
weight mode only. See Note 2 below. On some
specially modified units, the serial port connector
or an additional internal connection to the display
TEST button can also be utilized for a remote
push button to initiate the manual send se-
quence.

transmitted, create
enough instantaneous
motion on the platform

a stable weight that
might occur if the item
were removed slowly.
