DESCRIPTION
2.1
Construction (Figure 1)
2.1.1
Mechanical
Main features:
2.1.2

Vendor’s keyboard having 24 fixed keys and up to 40 programmable
keys.

Vendor’s display having four numeric fields, one alphanumeric field, and
several annunciators. A typical layout is shown in Figure 2.

Customer’s display. The layout and legends are identical to the vendor’s
display.

Diecast chassis and plastic housing.

Stainless steel load receptor having four pillars fitting through holes in
housing.
Load cell
The load cell is an Avery T103.
2.1.3
Circuit boards
The main PCB is mounted horizontally, above the power supply unit, which is in a
metal box. The two displays each have their own PCB.
2.2
Operation
2.2.1
Switch-on
At switch-on, the instrument performs a self-test during which all the relevant
segments of both displays are lit. The instrument attempts to set zero provided that it
is within a range of 20% of its capacity.
2.2.2
Zero-tracking
Zero-tracking operates provided that the instrument is within a range of 4% of its
capacity.
2/12
2.2.3
Semi-automatic zero setting
The zero button operates provided that the instrument is within a range of 4% of its
capacity.
2.2.4
Automatic zero setting
Automatic zero setting operates only when the instrument has been stable below
zero for at least 5 seconds.
2.2.5
Over-and under- range
If the load is less than gross zero, then the weight and price-to-pay indications are
inhibited and replaced by a series of bars using the lower display segments.
If the load is more than nine divisions above the maximum capacity, then the weight
and price-to-pay indications are inhibited and replaced by a series of bars using the
upper display segments.
2.2.6
Tare
Semi-automatic subtractive tare balancing or tare weighing can be performed,
dependent upon configuration. The maximum tare is equal to capacity.
Preset tares may be associated with PLU (Price Look-Up) files, or may be keyboard
assigned in which case the instrument is set up with a subtractive tare weighing device.
The maximum tare is equal to capacity (single interval versions only) or the limit of the
first partial weighing range (multi-interval versions).
2.3
Software
The software version numbers for the instrument are shown on the ‘test report’ printout
which may be obtained by double pressing the ‘test button’ and shall be as follows:
"772C11M series BOOT va.x.x "
"773C11M series APP vb.x.x"
(where “a” maybe 3, 4, 5, 6, or 7, “b” may also be 3, 4, 5, 6, or 7, and "x" reflects minor,
non-legally relevant software changes).
