CAUTION Warning of a possibly dangerous situation which can lead to less severe injuries or damage. NOTE Tips and important rules on the correct operation of the balance.
■ 9 Set up Set up Unpacking the balance The balances are delivered in an environmentally-friendly package, specifically developed for this precision instrument, which provides optimum protection for the balance during transportation. NOTE Retain the original packaging in order to avoid transportation damages when shipping or transporting the balance and to allow the balance to be stored in the best conditions if it is out of operation for an extended period.
9 Set up ■ Choosing a suitable location The balance location must be chosen in such a way as to guarantee perfect operation of your balance, so that the allowable ambient conditions and prerequisites are met and maintained: • Put the balance on a solid, firm and preferably vibration-proof, horizontal base •...
■ 9 Set up NOTE The balance must be calibrated on initial installation and after every relocation. If you work in accordance with “Good Laboratory Practice GLP” observe the prescribed intervals between calibrations (adjustments). Calibration is effected in the configuration menu. Depending on the balance model, this may be done exter- nally, internally or automatically (see chapter 10.3.4 "Calibration functions"...
