4.3 Selecting the Location and Leveling the Balance
Your balance is a precision instrument and will thank you for an optimum location with high accuracy and
dependability.
4.3.1 Selecting the Location
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:
●
Direct sunlight
4.3.2 Leveling the Balance
●
Powerful drafts (e.g. from fans or air conditioners)
●
Excessive temperature fluctuations
The balances have a level indicator and two or four adjustable leveling
feet to compensate for slight irregularities in the surface of the weighing
bench. The balance is exactly horizontal when the air bubble is in the
middle of the level glass.
Note: The balance should be leveled and adjusted each time it is
moved to a new location.
Balances with 2 leveling feet
Adjust the two front leveling feet appropriately until the air bubble
comes to rest exactly in the middle of the glass:
Air bubble at"12 o'clock"turn both feet clockwise
Air bubble at"3 o'clock"turn left foot clockwise, right
foot counterclockwise
Air bubble at"6 o'clock"turn both feet counterclockwise
Air bubble at"9 o'clock"turn left foot counterclockwise,
right foot clockwise
14Setting up the Balance
Page 15
Balances with 4 leveling feet
a) First turn the two rear leveling feet all the way in.
b) Adjust the two front leveling feet as previously described.
c) Turn the rear leveling feet down onto the surface for extra stabiliz
ing safety, so the balance cannot tilt over under eccentric loads.
4.4 Power Supply
Allow your balance to warm up for 30 minutes (0.1 mg models 60 minutes) to enable it
to adapt itself to the ambient conditions.
4.4.1 AC Operation
Your balance is supplied with an country-specific AC adapter or with a country-specific power cable. The power
supply is suitable for all line voltages in the range: 100 - 240 VAC, 50/60 Hz (for exact specifications, see
section "technical data").
First, check the local line voltage is in the range 100 - 240 VAC, 50/60 Hz and whether the
power plug fits your local power supply connection. If this is not the case, on no accountconnect the balance or the AC adapter to the power supply, but contact the responsible
METTLER TOLEDO dealer.
Important:
●
Before operating, check all cables for damage.
●
Guide the cables so that they cannot become damaged or interfere with the weighing
process!
●
Take care that the AC adapter cannot come into contact with liquids!
●
The power plug must be always accessible.
Connect the AC adapter to the connection socket on the back of your
balance (see figure) and to the power line.
4.4.2 Battery Operation
The Balance can also operates with batteries. Under normal operation conditions, the balance works indepen
dently of the AC power line for about 8 to 15 hours (using alkaline batteries). Immediately after the AC power
supply is interrupted e.g. by withdrawing the power plug or if there is a power failure, the balance switches
automatically to battery operation. Once the AC power supply is restored, the balance reverts automatically to
AC operation.
Note: It is also possible to use rechargeable batteries. Charging batteries inside the balance is not possible.

6 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, mild cleaning agent.
Please observe the following notes:
●
The balance must be disconnected from the power supply
●
Ensure that no liquid comes into contact with the balance or the AC adapter.
●
Never open the balance or AC adapter – they contain no components, which can be
cleaned, repaired or replaced by the user.
●
On no account use cleaning agents which contain solvents or abrasive ingredients, as
this can result in damage to the operation panel overlay.
●
Do not use wet, but only damp cloth for cleaning.
