6.4 Mains connection (optional) Power is supplied via the external mains adapter. The stated voltage value must be the same as the local voltage. Only use original KERN mains adapters. Using other makes requires consent by KERN. 6.5 Initial Commissioning In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chap.
6.6 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).
7.2 Weighing Operation Display Start balance by pressing Await zero display Place goods onto weighing plate. Now the weight is displayed, after the standstill control appears the weighing unit [kg] right-hand in the display. (example) If the material to be weighed is heavier than the weighing range, the display will show [E] (=Overload).
7.4 Plus/minus weighing Operation Display Turn on weighing scale and wait for zero to be displayed. Put the nominal weight on the weighing plate and tare (example) to [0] using the button. Remove the nominal weight. The nominal weight appears as negative display.
Spilled weighing goods must be removed immediately. 8.2 Servicing, maintenance The appliance may only be opened by trained service technicians who are authorized by KERN. Before opening, disconnect from power supply. 8.3 Disposal Disposal of packaging and appliance must be carried out by operator according to valid national or regional law of the location where the appliance is used.
