1 Introduction
Thank you for choosing a METTLER TOLEDO balance. The balance combines high performance with ease of
use.
This document is based on the software version V2.0.301.
Disclaimer for comparators
In this document, the term "balance" is used to describe both balances and comparators.
Comparators are characterized by their higher resolution compared to balances and are mainly used for differ-
ential weighing application, such as the calibration of standard weights. Beside standard balance tests,
comparators have also been tested with differential repeatability (ABA repeatability) during production.

United States of America
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be required to correct the interference at his own
expense.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause undesired
operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.

instrument according to these documents or if the instrument is modified, the safety of the instrument may be
impaired and Mettler-Toledo GmbH assumes no liability.
2.1 Definitions of signal words and warning symbols
Safety notes contain important information on safety issues. Ignoring the safety notes may lead to personal
injury, damage to the instrument, malfunctions and false results. Safety notes are marked with the following
signal words and warning symbols:
Signal words
DANGER

3 Design and Function
3.1 Function description
The XPR line comprises a range of balances that differ from each other due to their weighing range and
resolution. The balances of the XPR line combine a large number of weighing and adjustment possibilities with
a simple operation handling.
The following features are common to all models of the XPR micro-analytical line:
• 7-inch capacitive color TFT-touch screen.
• History about performed tests and adjustments, as well as changes applied to the balance settings.
• Built-in level sensor and leveling aid for fast and easy leveling.
• Fully automatic adjustment using internal weights.
• Various methods that can be defined individually.
• Various routine tests that can be defined individually.
• Functions to manage user groups and user rights.
• Integrated StaticDetect functionality for the detection of electrostatic charges inside the draft shield .
• Motor driven side doors and also top door.
• Built-in SmartSens optical sensors for touchless door operation.
• Easily removable draft shield elements.

3.3 Components description
3.3.1 Draft shield
The draft shield is a housing device that protects the
weighing area against environmental impacts like
drafts or moisture. The side doors and the top door
can be opened manually or automatically with a
touchless sensor.
3.3.2 Inner draft shield
The inner draft shield is a housing inside the draft
shield. The inner draft shield protects the weighing
area against small environmental impacts like drafts
or moisture. The inner draft shield side doors can be
opened automatically with a touchless sensor. The
top door has an opening for placing samples into the
weighing chamber.
3.3.3 Weighing pan
The weighing pan is the load receptor that serves
directly to accommodate the weighing item.
Design and Function14 Micro-Analytical Balances and Comparators
3.3.4 Drip tray
The drip tray is positioned below the weighing pan on
the weighing chamber base plate. The primary
purpose of a drip tray is to ensure quick cleaning of
the balance. Furthermore, the StaticDetect drip tray
detects static charges.
3.3.5 Removable clips
The removable clips help to insert cables or
measurement devices like sensors or an ionizer into
the weighing chamber without opening the doors of
the draft shield.
3.3.6 Door handle
The door handles are mounted on the door slides and
are used to open the side and top doors of the draft
shield manually.
Design and Function 15Micro-Analytical Balances and Comparators
3.3.7 Leveling feet
The balance stands on two height-adjustable feet.
These feet are used to level the balance.
3.3.8 Terminal
The 7-inch balance terminal has a touch sensitive
display. Further, on the front side of the terminal is a
StatusLight LED strip that indicates the current status
of the balance.
3.3.9 Optical sensors
The optical sensors SmartSens are located on the
weighing unit behind the doors and provide a
touchless door handling. When the optical sensors
are activated, the doors can be opened without
touching them by moving the hand over the sensor.
Design and Function16 Micro-Analytical Balances and Comparators
3.3.10 Side door release lever
The side door release lever is located on the back side
of the partition panel and locks/unlocks the draft
shield side door.

Note
Do not disconnect the balance from the power supply unless the balance is not
used for an extended period of time.

Zero Zeroes the balance.
The balance must always be zeroed before starting the weighing process. After

System messages can appear due to a user action, a user input or a system process. Some messages leave it
up to the user to choose upon acting, they will disappear after acknowledging. Other messages remain
persistent, so the user can defer them but eventually has to handle them. These messages can be seen in the

Stability indicator When the stability indicator appears, the balance is not stable.
Make sure that the balance is placed at an adequate location.
Information about the adequate location can be found in the
section Selecting the location.
Net indicator Appears when the tare key has been pressed and the tare weight
has been subtracted.
Calculated value The current weight value is calculated. This symbol only appears
in the weighing value area when a container has been used with
the function Preset tare.
Minimum weight violation The current weight value is smaller than the defined minimum
weight. Make sure that the weight is larger than the minimum
weight.
Balance invalid The current balance configuration is invalid or quality criteria have
not been fulfilled according to the GWP approved definition.
Weight not ready The current weight measurement is not ready according to the
GWP approved definition. This can be caused an overload, an
underload, or a minimum weight violation.
Weight ready The current weight measurement is ready according to the GWP
approved definition. It can be added to the protocol.

4.1 Selecting the location
A balance is a sensitive precision instrument. The location where it is placed will have a profound effect on the
accuracy of the weighing results.
Requirements of the location
Place indoors on stable
table
Avoid direct sunlight Avoid vibrations Avoid strong drafts Avoid temperature fluctu-
Ensure sufficient spacing Level the instrument Provide adequate lighting
ations
Sufficient spacing for balances: > 15 cm all around the instrument
Take into account the environmental conditions. See "Technical Data".
4.2 Unpacking the balance
Check the package, the packaging elements and the delivered components for damages. If any components
are damaged, please contact your METTLER TOLEDO service representative.
Depending on the balance model, the components may look different. The procedure is always the same.
