2.1 Unpacking / standard equipment
The standard equipment for every balance comprises:
• AC adapter, to national standard
• Weighing pan, Weighing pan sup-port, draft shield element (de-pending on model)
• Draft shield
standard supply with models of 0.1 /1 mg readability (
for other models
available as an optional extra
)
• Operating instructions
• Protective cover for compact balances PL-S (placed on the balance over the weighing cell cone) with instruction sheet. This protective
cover must not be mislaid. It will be needed again later to protect the cone when changing batteries (underside of balance).
1) In-use covers are available as optional extras (Section 6.4). In the case of models having the large weighing pan (ø 160 mm),
the antistatic plate a) (secured by two screws) and the adapter ring b) must also be removed in order to fit the in-use cover.

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.
Leveling
Some models are equipped with a level glass and two or four 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.
