This manual explains the operation of the 7050
bulk sampling scale. The 7050 is a computer-
based counting scale specifically configured
for bulk mail applications.
This manual explains only the basic application
which ships from the factory and also
assumes all the functions of the scale are
enabled. Your scale has been configured for
your particular application.
This manual is divided into the following main
sections:
• Unpacking and Preparing the 7050
• 7050 Description
• Weighing Operations
• Bulk Sampling Operations
The unit must be
plugged into an
easily accessible
outlet that is earth
grounded and of the
appropriate
voltage.
Introduction
Unpacking and Preparing the 7050
When you receive your 7050, unpack the unit
and save all shipping materials. Remove the
protective plastic from the scale platform.
Place the scale on a level, vibration free
surface. Level the scale with the help of the
bubble level under the scale platform. Turn the
screw feet until the bubble is centered and the
scale does not rock. Tighten the knurled locking
knobs above each foot against the scale base.
Plug the unit into the appropriate power source.
Keep in mind that the power receptacle must
be earth grounded and easily accessible to the
user.
Press any key to activate the scale.

The 7050 is a 12"x 14" scale with an attached
5" x 12" display housing. See Figure 1. The
scale base is cast aluminum enclosing a
QDT®(Quartzell®Digital Technology) weight
sensor and electronics package. The scale
platter is stainless steel.
The display is a 64" x 240" dot matrix which
allows several lines of text and the ability to
display graphics.
There are five softkeys located directly below
the display, a numeric keypad to the right and
six other labeled keys. The keys will be
described in the next section.
Built into the 7050 are two serial ports (Com1
and Com2). Com1 is used for 3635 QDT®base
connection only. Com2 is used for Orion printer
connection only.
The keys on the front panel of the 7050 are of
two types; hard keys and softkeys. Hard keys
are labeled directly and softkey labels appear on
