KERN HFT 3T0.5 Operating Manual

10 HFT-BA-e-18122.4 Environmental conditions• Never operate the crane scales in explosive environment. The serial version isnot explosion protected.• Operate the crane scales only under environmental conditions as specified inthese 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 istaken to a considerably warmer environment. In this case, acclimatize thedisconnected 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 shouldelectromagnetic fields (e.g. due to mobile phones or radio equipment), staticelectricity accumulations or instable power supply occur. Change location orremove source of interference.2.5 Proper useThe balance you purchased is intended to determine the weighing value of materialto be weighed. It is intended to be used as a “non-automatic“ balance, i.e. thematerial 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 theweighing 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 ofload 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 notallowed.2.6 Improper UseDo not use balance for dynamic weighing. In the event that small quantities areremoved or added to the material to be weighed, incorrect weighing results can bedisplayed due to the “stability compensation“. (Example: Slowly draining fluids from acontainer suspended on the balance.) Do not leave permanent load suspended onthe balance. This may damage the measuring system as well as safety-relevantparts.The balance may only be used according to the described conditions. Other areas ofuse must be released by KERN in writing.
