PREPARING THE SCALE FOR USE
This chapter gives detailed instructions and important information regarding the successful installation of the
METTLER TOLEDO Xpress XRW 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 Xpress representative.

Note: The rear feet should be against the body of the scale
tightly when cleaning the scale. After the scale has been
cleaned, loosen the rear feet, this allows the internal and
external pressure to equalize.

POWER UP/DOWN SEQUENCE
Power Up: Press the power key
to turn on the METTLER TOLEDO Xpress XRW. It goes through a series
of self-tests when it is turned on. The scale performs diagnostics on its internal memory, and precedes to
normal the operating mode. The power up sequence is as follows:
z All segments of the display segments and cursors light to verify operation.
z Next the unit displays the software part number; revision number, GEO value and country one by one.
z The unit captures zero and is ready for normal operation.
Note: Before switching on the METTLER TOLEDO Xpress XRW scale, always make sure there is nothing on
the platter. If you have powered up the unit with something on the scale, the scale may not find the zero
value, and shows
“------“. To clear this condition remove the item, press the power key until the unit displays “off”. Then press
the power key again and the scale will then capture the correct zero value.
Power Down: Press the power key
until “off” is shown on the display to turn off the scale.
