When connecting to an AC power supply, the battery can be automatically recharged. The charging
cursor is “on” above the battery charging symbol . The charging time is usually 12 hours. If the
charging is complete, the cursor will be off.
Never invert the positive and negative poles of battery. The red terminal is for the positive pole ,
the black terminal is for the black plug.
The battery must be taken out when the scale is not used for long periods of time. The battery should be
recharged at least once every three months.
Do not use another type of battery to replace the one supplied with the scale.
FAILURE TO FOLLOW THESE PRECAUTIONS COULD RESULT IN DAMAGE TO OR DESTRUCTION OF THE
EQUIPMENT, OR BODILY HARM.

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.
