ECONOMY COUNTING SCALE
PREPARING THE SCALE FOR USE
The Xpress XTCII is a new generation counting scale. With high internal and display resolution as well as a
unique profile, the XTCII can widely be used in counting applications in the electronics, metals, plastics and
other such industries. The Xpress XTCII is ready to use right out of the box.
This manual provides not only the detailed information on how to operate the scale, but also useful
messages for service and maintenance.
Please read the manual thoroughly and familiarize yourself with all the safety requirements. All service
procedures must only be performed by authorized personnel.
This chapter gives detailed instructions and important information regarding the successful installation of the
Xpress Economy Counting Scale.
ENVIRONMENT
Before you install the scale, identify the best location for the equipment. The proper environment enhances
its operation and longevity. Keep in mind the following factors, which might have a negative influence on
the scale's operation:
Vibration: Vibration diminishes the scale’s ability to measure accurately. Electrical machinery such as
conveyors and drill presses can cause inaccurate and non-repeatable readings. The scale may also read
inaccurately if it is not leveled properly.
Air currents: Moving air can cause the scale to read wind movement as an additional force and cause
inconsistency in the weighing results.
Friction: A scale cannot measure accurately if an object is rubbing or pressing against the scale platform.
UNPACKING AND ASSEMBLY
Please inspect the package immediately upon receipt. If the box is damaged, check for internal damage and
file a freight claim with the carrier if necessary. If the container is undamaged, open the box, remove the
scale and place it on a solid, flat surface. Please keep the packing material and shipping insert in case you
need to return the scale to an MT Xpress representative.

OPERATING YOUR SCALE
ZERO
Press to capture a new center of zero if the scale is in gross weight mode and the weight on the scale is
stable (e.g. 0.5000 lb, as above shown, the cursor ‘Stab’ is on). The cursor “0” is lit when a new center of
zero is captured.
TARE
Pressing the key subtracts the weight of the object on the scale platform from subsequence indications
of weight. Tare is most often used to subtract the weight an empty container. The key is used as well to
clear a previously entered tare value if the scale is in net mode.
Direct Tare
Press the key in gross weight mode when the weight on the scale is above zero (e.g. 0.5000 lb as
above shown) to tare the scale. If a net center of zero can be captured, the cursor ‘Net’ is on. By pressing the
key
again, the scale will be back in gross weight mode. The tare range is the full capacity of the scale.
Input Tare (Digit Tare)
If the Function F3 in the Setup Mode is set to 1 (F3=1, see Setup Mode), the scale can be tared manually
without weighing-in the tare value. Press the key to enter a tare value. The QTY window displays
“InTare” to remind you to enter the tare. The input tare is displayed in the APW window and can be corrected
by pressing the key
if a wrong figure is entered. By pressing the key , you confirm the input tare
value. The display shows the negative tar value in the weight window with the cursor “Net” on.
The input tare can be cleared by pressing the key again, and the scale is then back to gross weight
mode.

COUNTING
Counting by Sampling
Place the samples on the platter (e.g. 20 pieces weights 0.05 lb as shown above). Press the key to
sample. The QTY window displays SPL. Enter the sample quantity 20, and then press the key to
confirm.
Press the key to correct or clear the input figure.
The Wt window displays the sample Weight; the APW window displays Average Piece Weight of samples
and the QTY displays the sample Quantity.
APW Enhancement
The APW (Average Piece Weight) enhancement can be activated in the Setup Mode (F5=1). This
enhancement is used to get a more accurate APW. After a sampling is complete, the scale will
automatically re-calculate the APW. However, the added quantity of pieces should be less than the quantity
on the scale. The scale gives a ‘beep’ after every APW enhancement. The function is always available
unless the added quantity of pieces is more than that the quantity on the scale.
For example:
Sampling with 20 pieces
that weight 0.04 lb and an
APW 0.002 lb.
If you add another 19 pieces
to the scale (≤ 20 pcs), a
beep indicates that the APW
is automatically recalculated
to 0.0020115 lb.
If you add another 39 pieces
to the scale (≤ 39 pcs), again,
a beep indicates that the APW
is automatically recalculated to
0.0020208 lb.

If you know the APW. . .
If you know the APW of your goods, the APW can be entered directly instead of sampling.
Place the goods on the scale (e.g. 0.05 lb). Press the key and enter the APW (e.g. 0.002 lb) of one
piece. The QTY window displays “Single” and the entered APW is displayed in the APW window. Press
to confirm. The QTY window displays now the total quantity of pieces (e.g. 25).
You may press the key
to correct or clear the input figure.
ACCUMULATION AND RECALL
The key can be used to keep the quantity in the memory. The cursor ‘M’ is lit when the accumulated
quantity is not zero. The Wt window displays ‘Total’ and the APW window displays accumulation times
(e.g. 3 times). The QTY window displays the accumulated quantity (e.g. 1500 pcs).
Press
to confirm, then the quantity of goods on the scale into memory (e.g. 500 pcs).
To clear the accumulation, press and the cursor “M” will be off.
Press to recall the total quantity and accumulation times (e.g. 2000 pcs, 4 times). Press to exit
recall.
When the accumulated quantity is above 999,999, the QTY window displays “nnnnnn” to indicate that
maximum number of accumulations has been reached.
.
If the weight on the scale hasn’t been changed between two accumulations, the QTY window will display
‘Again’ to refuse the operation.
ALARM
The alarm function includes a weight and a quantity alarm. Both alarms can either be set to sound within a
defined range or over/under a defined range. The alarm function can be activated in the Setup Mode
(F4/F4.1/F4.2/F4.3).
Page 12

ECONOMY COUNTING SCALE
Temporarily Disable the Alarm Beep
For all functions, the alarm beep can be deactivated by pressing the key . Pressing again will
reactivate the alarm beep.
Weight Alarm within a Range
If weight alarm within a range is activated in the Setup Mode, press the key to set the alarm range. The
QTY window displays ‘Lo 1’ to remind you to enter the lower limit of the alarm range. The entered lower
range is displayed in the APW window (e.g. 0.500 lb). Press the key to confirm the lower limit. The
QTY window now displays ‘Hi 1’ to remind you to enter the upper limit of the alarm range (e.g. 1.000 lb).
Press to complete the alarm range setting.
If the weight on the scale is within the alarm range (e.g. 0.800 lb on the scale, i.e. ≥ 0.500 lb and ≤
0.1000 lb), the scale will beep continuously, and the cursors “Lo” and ”Hi” will be lit. If the weight on the
scale is less than the lower limit, the cursor ‘Lo’ will be on. The ‘Hi’ is on when the weight is higher than the
upper limit.
Weight Alarm beyond a Range
If weight alarm beyond a range is activated in the Setup Mode, press to set the alarm range. The QTY
window displays ‘Lo 1’ to remind you to enter the lower limit of the alarm range. The entered lower range is
displayed in the APW window (e.g. 0.5 lb). Press to confirm the lower limit. The QTY window now
displays ‘Hi 1’ to remind you to enter the upper limit of alarm range (e.g. 0.1000 lb). Press to
complete the alarm setting. If the weight on the scale is beyond the alarm range (e.g. 1.200 lb on the
scale, i.e. < 0.500 lb or > 0.1000 lb) the scale will beep continuously. The cursor “Lo” will be on if the
weight on the scale is less than the lower limit. The ‘Hi’ cursor is on when the weight is higher than the
upper limit.
Quantity Alarm
The two quantity alarms (within a range/beyond a range) work the same way as the weight alarms. Instead
of “Lo 1” and ‘Hi 1’, “Lo 2” and ‘Lo 2’ are indicated.
