9.9 Connecting the power supply
Power is supplied by the external power unit which also serves to isolate the mains
supply from the scale. The stated voltage value must be the same as the local
voltage.
Only approved genuine KERN power supply units may be used in compliance with
Directive EN 60601-1.
9.10 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. 1). During this
warming up time the balance must be connected to the power supply (mains,
accumulator or battery) and be switched on.
The accuracy of the balance depends on the local acceleration of gravity.
The value of gravity acceleration is shown on the type plate.
