Disclaimer for comparators
In this document "balance" is a terminology preamble and stands for comparators.
Comparators are characterized by their higher resolution compared to balances and are mainly used for
differential 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.
This information is valid for models of the line/s:
• XPR6U

3.3 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.
• Choose a solid table that is as horizontal as possible. Choose
the table according to the maximum capacity of the balance.
• The balance must only be used indoors and up to a maximum
altitude of 4,000m above sea level.
• Before switching on the balance, wait until all parts are at room
temperature (10 °C to 30°C).
The humidity must be between 10% and 80% non-condensing.
• The power plug must be accessible
• Firm, horizontal and vibration-free location
• No direct sunlight.
• No excessive temperature fluctuations
• No strong drafts
3.4 Assembling the balance
After checking the scope of delivery, unpacking the balance and after finding a proper location the balance

− Use the terminal connection cable to connect the terminal with the weighing unit.
3.5.2 Connecting the balance to the mains
WARNING
Danger of death or serious injury due to electric shock.
Contact with parts that contain a live current can lead to injury and death.
1 To connect the balance, only use the supplied three-core power cable with equipment
grounding conductor.
2 Only use a three-pin power socket with earthing contact.
3 Only use standardized extension cable with equipment grounding conductor.
4 Do not disconnect the equipment grounding conductor.
NOTICE
Damage to the balance due to short circuit!
Damage to the insulation on the AC/DC adapter can result in a short circuit and damage the
balance.
1 Only use the original AC/DC adapter supplied with your balance.
2 Route the cable so that it cannot be damaged by external influences.
3 Make sure that the power plug is always accessible.
Note
The balance is supplied with an AC/DC adapter and a country-specific power cable. The AC/DC adapter is
suitable for use with the following voltage range:
100 – 240 VAC, 50/60Hz.
Connect the balance to the mains as follows:
Installation and Putting into Operation14 XPR
Page 15
1 Check whether your local power supply falls within the
range of the delivered AC/DC adapter. If this is not the
case, under no circumstances connect the AC/DC
adapter to the power supply, but contact a METTLER
TOLEDO representative.
2 Connect the AC/DC adapter to the AC/DC socket of the
balance.
3 Use the power cable to connect the AC/DC adapter to
the mains.
ð The balance performs a self-test after connection to the
power supply and is then ready to use.

4 Maintenance
4.1 Cleaning
We recommend periodically cleaning the draft shield, the weighing platform, and the terminal. For cleaning
the weighing chamber use the brush supplied with it. The maintenance interval depends on your standard
operating procedure (SOP). The balance is made of high-quality, resistant materials and can therefore be
cleaned with a commercially available, mild cleaning agent.
WARNING
Danger of death or serious injury due to electric shock!
Contact with parts that contain a live current can lead to injury and death. If the device cannot
be shut down in an emergency situation, people can be injured or the device can be
damaged.
1 Disconnect the device from the power supply prior to cleaning and maintenance.
2 Only use METTLER TOLEDO power cables, if these need to be replaced.
3 Make sure that no liquid enters the device or AC/DC adapter.
4 Do not open the device or AC/DC adapter. These do not contain any user-serviceable
parts.
NOTICE
Damage of the balance due to the use of inappropriate cleaning agents!
− On no account use cleaning agents which contain solvents or abrasive ingredients, as
this can result in damage to the terminal overlay.
Note
Please contact your METTLER TOLEDO dealer for details of the available service options. Regular servicing
by an authorized service engineer ensures constant accuracy for years to come and prolongs the life of your
balance.
