Observe the information in the operating instructions Please read the operating instructions carefully before erecting and commissioning, even if you already have experience with KERN balances. Staff training The device may only be operated and looked after by trained members of staff.
5 Unpacking, installation and commissioning Place of installation, place of use The balance is constructed in such a way that reliable weighing results can be achieved under normal application conditions. By selecting the correct location for your balance, you will be able to work quickly and precisely.
Electric power supply is by means of the external mains supply circuit. The printed voltage level must comply with the local voltage. Only use original KERN mains supply circuits. The use of other makes is subject to approval by Kern.
Adjustment As the acceleration value due to gravity is not the same at every location on earth, each balance must be coordinated – in compliance with the underlying physical weighing principle - to the existing acceleration due to gravity at its place of location ( only if the balance has not already been adjusted to the location in the factory).
Hang the item to be weighed on the hook and carry out weighing. Fig. 1: Setting up the balance for underfloor weighings For the underfloor weighing use only the original hook of KERN. Take care that all hanged items are stable enough to hold the goods which you wish to weigh (!!Danger of breaking!!).

Remove any spilt material to be weighed immediately. Maintenance, upkeep The device may only be opened by trained service engineers authorised by KERN. Disconnect from the mains supply before opening. Disposal The operating company shall dispose of the packaging and the device in compliance with the valid national or regional law of the operating location.
8 Troubleshooting The balance should be switched off for a short time following an interruption in the programme sequence and disconnected from the mains supply. It is then necessary to repeat the weighing process from the beginning. Help: Interruption Possible cause Weight display is not illuminated.
