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.
4.3.2 Leveling the Balance
Observe ambient conditions (see Technical Data).
Avoid the following:
●
Direct sunlight
●
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
ML Models16
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
Setting up the Balance
Air bubble at "6 o'clock" turn both feet counterclockwise
Air bubble at "9 o'clock" turn left foot counterclockwise,
right foot clockwise
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 stabilizing
safety, so the balance cannot tilt over under eccentric loads.
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 account con
nect 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 bal
ance (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 independently
of the AC power line for about 8 to 15 hours (using alkaline batteries). Immediately after the AC power supply is
ML Models 17
Setting up the Balance
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.
battery fully When the balance is operating on its batteries, the battery symbol in the
display lights up. The number of segments that are lit is an indicator of
battery condition (3 = fully charged, 0 = discharged). When the batteries
2/3 full
are almost completely discharged, the battery symbol flashes.
1/3 full

Section "Selecting the location" regarding the choice of an optimal location.
Transporting Over Short Distances
For balances with a draft shield: Observe the following instructions to transport your balance
over a short distance to a new location: Never lift the balance using the glass draft shield.
The draft shield is not sufficiently fastened to the balance.
Transporting Over Long Distances
If you would like to transport or send your balance over long distances, use the complete original packaging.
4.6 Weighing Below the Balance
The balances are equipped with a hanger for carrying out weighings below the work surface (weighing below the
balance).
Attention:
●
Do not place the balance on the pan support location bolt.
a) Switch off the balance and remove the power cable and any
interface cable from the balance.
b) Remove weighing pan, pan support and draft shield element or
"Easy draft shield" if present.

d) Remove one of the caps (A) depending on the models.
e) Then turn the balance to its normal position and simply rein
stall all components in the reverse order.
4.7 Adjustment (Calibration)
To obtain accurate weighing results, the balance must be adjusted to match the gravitational
acceleration at its location. Adjusting is necessary:
●
before the balance is used for the first time.
●
at regular intervals during weighing service.
●
after a change of location.
4.7.1 Adjustment with Internal Weight
Note: On models with internal weight only (see technical data).
To obtain accurate results, the balance must be connected to the power supply for approxi
