VHB-BA-e-181486 Unpacking, Setup and Commissioning6.1 Site of installation, place of operation for scalesThe balances are designed in a way that reliable weighing results are achieved incommon conditions of use.You will work accurately and fast, if you select the right location for your balance.Therefore, observe the following for the installation site: The load must be lifted clear of the display unit’s case and other pallets.Incorrect lifting of a load Correct lifting of a load The accuracy of the weighing system is falling by approximately 0.1 % perdegree if there is a slant of more than 2°. Holes and unevenness, too, havethis effect. A smooth floor is ideal. Optimum accuracy in weighing results is achieved if the load centre isbetween the forks. The forks are easily bent and twisted when the load is off-centre. This may result in diminished accuracy. In verifiable models off-centreloads, or slants affecting accuracy, activate the inclination switch which in turndisconnects the display.Non-optimal positioning of load Optimal positioning of load Temperature range: The maximum deviation for 0.1% of the weighed load isbetween -10 and +40°C. Outside this temperature range deviations of up to0.3% may occur. Avoid jarring during weighing Protect the balance against high humidity, vapours and dust Do not expose the device to extreme dampness for longer periods of time.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 roomtemperature. Major display deviations (incorrect weighing results) may be experiencedshould electromagnetic fields (e.g. due to mobile phones or radio equipment),static electricity accumulations or instable power supply occur. Changelocation or remove source of interference.
