2.4  Environmental conditions 

  Never operate the crane scales in explosive environment. The serial version is 

not explosion protected. 

  Operate the crane scales only under environmental conditions as specified in 

these operating instructions (especially in chapter 1 „Technical data“). 

  Do not expose the crane scales to strong humidity. Non-permitted condensation 

(condensation of air humidity on the appliance) may occur if a cold appliance is 
taken to a considerably warmer environment. In this case, acclimatize the 
disconnected appliance for ca. 2 hours at room temperature. 

  Do not operate the crane scales in corrosive environment. 

  Protect the crane scales against high humidity, vapours and dust. 

  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.  

2.5  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. 
 

  Use the crane scales only for lifting and weighing of freely movable loads. 

  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. 

  Modifications or reconstructions of the crane scales or of the crane are not 

allowed. 

 

2.6  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“. (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.
