Operate the device in a room where the temperature ranges between 15–30 °C
(59–86 °F) and where the relative humidity is below 80%. Any changes
in temperature should be gradual and very slow.
Place the balance on a solid surface to ensure stability. To obtain stable and
repeatable weighing results, an anti-vibration table is recommended.

Do not place the balance in a hazard-
ous area. Do not weigh explosive
materials.
Do not place the balance on an
unstable ground exposed to shocks
and vibrations.

External adjustment is carried out using an external mass standard of the
right accuracy and weight value, which value depends on balance type
and capacity. WLC 1/A2 1 000
