1 Getting to know L/L-S balances line
1.1 General (Types of construction, Balance features)
Compact construction
Standard construction
Several types of construction – uniform operation
• The L/L-S balance line ranges from high-resolution analytical balances (AL) with
a readability of 0.1 mg through to precision balances (PL/PL-S) with a
readability of 0.001 g to 1 g. The weighing ranges extend from 51 g to 6.1 kg.
• The operation of all theses balances is identical.
Balance features
• In addition to basic operations such as weighing, taring and adjusting (calibra-
tion) miscellaneous functions such as “Piece counting”, “Percent weighing”,
“Dynamic weighing”, “+/- Weighing” or “Free factor” can be activated.
• Several L/L-S balances are fitted with a glass draft shield in the factory; with other
models a draft shield is available as an optional extra.
Notes
• Models of Line AL and PL-S balances are available as certified versions. Please
ask your METTLER TOLEDO dealer for details.
• If you wish to build on what you have learned about weighing in these operating
instructions, you will find valuable tips in booklet Order No. 720906 “Weighing
the right way”.
