HFM-BA-e-1011 6
ƒ Major display deviations (incorrect weighing results) may be experienced should
electromagnetic fields (e.g. due to mobile phones or radio equipment), static
electricity accumulations or instable power supply occur. Change location or
remove source of interference.
Proper use
The balance you purchased is intended to determine the weighing value of material
to be weighed. It is intended to be used as a “non-automatic“ balance, i.e. the
material to be weighed is suspended on the crane hook only vertically, manually,
carefully and without jerks. As soon as a stable weighing value is reached the
weighing value can be read.
ƒ
Use the crane scales only for lifting and weighing of freely movable loads.
ƒ Danger of injury due to improper use. Not allowed are e.g.:
-
Exceeding the allowed nominal load of crane, crane scales or any type of
load attachment devices
-
Conveying persons,
-
Pulling loads over an inclined surface,
-
Tearing-off, pulling or towing loads.
ƒ Modifications or reconstructions of the crane scales or of the crane are not
allowed.
Improper Use
Do not use balance for dynamic weighing. In the event that small quantities are
removed or added to the material to be weighed, incorrect weighing results can be
displayed due to the “stability compensation“ in the balance. (Example: Slowly
draining fluids from a container suspended on the balance.) Do not leave permanent
load suspended on the balance. This may damage the measuring system as well as
safety-relevant parts.
The balance may only be used according to the described conditions. Other areas of
use must be released by KERN in writing.
