3.4 Selecting a location
Your balance is a precision instrument and will thank you for an optimum location with high
accuracy and dependability. Select a stable, vibration-free position that is as horizontal as possible.
The surface must be able to safely carry the weight of a fully loaded balance.
Observe ambient conditions see Technical Data.
Avoid the following:
•Vibrations
•Excessive temperature fluctuations
•Direct sunlight
•Powerful drafts (e.g. from fans or air conditioners)
3.5 Connecting the balance
WARNING
Risk of electric shock
1 Only connect the balance to a three-pin power socket with earthing contact.
2 Only standardized extension cable with equipment grounding conductor must be
used for operation of the balance.
3 Intentional disconnection of the equipment grounding conductor is forbidden.
The balance is supplied with an universal AC adapter and a country-specific plug. The AC adapter is
suitable for use with the following voltage range:
100 – 240 VAC, 50/60Hz.
NOTICE
Danger of damage to the AC adapter due to overheating or incorrect voltage range!
If the AC adapter is covered or in a container, it is not sufficiently cooled and overheats.
If the voltage is too high for the device in use, the device might be damaged or the cable
might start to burn.
If the voltage is too low, use of the device might be restricted or the device might not
function at all.
1 Do not cover the AC adapter.
2 Do not put the AC adapter in a container.
3 Check whether your local power supply falls within this range. If this is not the
case, under no circumstances connect the AC adapter to the power supply, but
contact a METTLER TOLEDO representative.
4 The power plug must be accessible at all times.
5 Prior to use, check the power cable for damage.
6 Route the cable in such a way that it cannot be damaged or cause a hindrance
when working.
7 Ensure that no liquid comes into contact with the AC adapter.
Installation and Putting into Operation 15Precision and Analytical Balances

− Connect the AC adapter to the connection socket on the back of
your balance (see figure) and to the power line.
ðThe balance performs a display test (all segments in the
display light up briefly), "WELCOME", Software version,
Maximum load and Readability appears briefly.
The balance is ready for use.
3.6 Setting up the balance
3.6.1 Switching on the balance
Before working with the balance, it must be warmed up in order to obtain accurate weighing results.
To reach operating temperature, the balance must be connected to the power supply for at least 30
minutes (0.1 mg models 60 minutes).
Switching on
§The Balance is in "STANDBY" mode. "MT.GREEN" appears on the
display.
− Press « » or remove any load from weighing pan or tap on the
weighing pan.
The balance is ready for weighing or for operation with the last active
application.
Note
Approved balances can only be switched on by pressing « » in
selected countries.

3.6.2 Leveling the balance
Note
The balance must be leveled and adjusted each time it is moved to a new location.
1 Align the balance horizontally.
2 Turning the two front leveling screws of the housing until the air
bubble is in the inner circle of the level indicator.
ðThe position of the air bubble illustrates which leveling screw
you need to turn (L = left leveling screw, R = right leveling
screw) and in which direction so that the air bubble moves to
the center.
Example
In this example, turn the left leveling screw counterclockwise.
3.6.3 Adjusting the balance
To obtain accurate weighing results, the balance must be adjusted to match the gravitational accel-
eration at its location and depending on the ambient conditions. After reaching the operation
temperature, adjusting is necessary
•before the balance is used for the first time.
•after a change of the location.
•at regular intervals during weighing service.

4 Maintenance
4.1 Cleaning and service
Every now and then, clean the weighing pan, draft shield element, bottom plate, draft shield
(depending on the model) and housing of your balance. Your balance is made from high-quality,
durable materials and can therefore be cleaned using a damp cloth or with a standard cleaning
agent.
To thoroughly clean the draft shield glass panels, remove the draft shield from the balance. When
reinstalling the draft shield, ensure that it is in the correct position.
Please observe the following notes:
WARNING
Risk of electric shock
1 Disconnect the balance from the power supply prior to cleaning and maintenance.
2 Only use METTLER TOLEDO power adapter, if these need to be replaced.
3 Ensure that no liquid comes into contact with the balance, terminal or AC adapter.
4 Do not open the balance or AC adapter.
These contain no user-serviceable parts.
CAUTION
Damage to balance
Under no circumstances use cleaning agents containing solvents or abrasive agents, as
this can damage the operation panel overlay.
Do not clean the IP65 protected models using high-pressure or high-temperature water.
Note
Contact a METTLER TOLEDO representative to find about the service options available – regular
maintenance by an authorized service engineer will ensure consistent weighing accuracy over the long
term and extend the service life of the balance.
