1.1 General
Balance features
• The L-IC balance line ranges from high-resolution analytical balances (AL-IC) with a readability of 0.1 mg through to precision
balances (PL-IC) with a readability of 0.001 g to 1 g. The weighing ranges extend from 51 g to 4.1 kg.
• The operation of all theses balances is identical.
• In addition to basic operations such as
counting”, “Percent weighing”, “Dynamic weighing”, “+/- Weighing” or “Free factor” can be activated.
• Several balances are fitted with a glass draft shield in the factory; with other models a draft shield is available as an optional
extra.
Note
All Models are available as certified versions. Please ask your METTLER TOLEDO dealer for details.

The balances have two operator control levels: the weighing mode and the menu. The function of each individual key depends
on the operator control level and how long the key is pressed.

Cautionary notes
2.3 Setting up, leveling, preparations for weighing below the balance
1) In-use covers are available as optional extras (Section 6.4).
• L-IC balances must
ply AC adapter.
connecting the AC adapter, verify that the voltage printed on it corresponds
• Before
to the local AC power supply voltage. If this is not the case, please contact your
local METTLER TOLEDO dealer.
• L-IC balances may only be used indoors in a dry environment.
• For use with CSA Certified (or equivalent approved) power source, which must
have a limited and SELV circuit output.
The optimum location
The correct location makes an important contribution to the accuracy of the weighing
results of high-resolution analytical and precision balances.
• Stable, vibration-free position as horizontal as possible
• No direct sunlight
• No excessive temperature fluctuations
• No drafts
The best location is on a stable bench in a corner protected against drafts, as far
away as possible from doors, windows, radiators or the louvers of air conditioners.
not be operated in hazardous areas with the standard-sup-
Leveling
All models are equipped with a level glass and two leveling feet to compensate
for minor irregularities in the surface on which the balance stands. The balance is
exactly horizontal when the air bubble is in the middle of the level glass.
Note: The balance should be leveled each time it is moved to a new location.
Preparations for weighing below the balance
To carry out weighing operations below the balance, get rid of the special cover on
the underside of the balance. (Note: never put the balance without the protective
cover over its cone down on its head, only on its side!). This exposes the opening
for the hanger, making weighing below the balance possible.

Antitheft device
All models are provided with a lug for attaching an antitheft device (see optional
equipment in Section 6.4).
Power supply
➞ Plug the AC adapter into the AC adapter socket on the balance, and connect to
the power supply.
➞ The balance performs a self-test. This test is finished when “OFF” appears.
➞ Press the «On» key briefly: the balance is in operational readiness. Before any
work is performed with the balance, it must be adjusted (Section 2.4).
Notes
To achieve accurate results with analytical balances (AL-IC), they must be left
switched on for at least 60 minutes to reach operating temperature before carrying
out the first weighing operation.
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
To obtain accurate results, the balance must be left switched on for 60 minutes to
reach operating temperature before starting the adjustment procedure.
Adjusting with internal weight
➞ To carry out tis operation, in the second menu option (Adjustment) select
“CAL int” (= factory setting) (section 4.1).
➞ Unload weighing pan.
➞ Press and hold the «Cal» key down until “CAL” appears in the display, then
release key.
➞ The balance adjusts itself automatically.
The adjusting is finished when the message «Cal done» appears briefly in the
display, followed by “0.00 g”. The balance is again in weighing mode and
ready for operation.

➞ Place adjustment weight in centre of pan. The balance adjusts itself auto-mati-
cally.
➞ When “0.00 g” flashes, remove adjustment weight.
The adjusting is finished when the message “CAL done” appears briefly in the
display, followed by “0.00 g”. The balance is again in weighing mode and ready
for operation.
