5.3 Mains connection
Power is supplied via the external mains adapter. The stated voltage value must be
the same as the local voltage. Only KERN original power packs should be used.
5.4 Battery operation (insertion and removal)
On models where the back of the display unit is not directly accessible, remove the
two black rotary knobs from both sides of the display unit in order to open the battery
compartment and remove the display unit from the holder. Remove battery cover
from under the display unit. Insert 6 x 1.5V AA batteries into the holder. Replace bat-
tery cover and screw the display unit back into the holder using the black rotary
knobs.
In order to save the battery, the balance switches automatically off after 3 minutes
without weighing. Further shutdown times can be set in the Menu
(Function "A.OFF"), see chapter 5.7.
If the batteries are run down, "LO" appears in the display. Press [ON/OFF] -key and
replace the batteries immediately.
If the balance is not used for a longer time, take out the batteries and store them
separately. Leaking battery liquid could damage the balance.
5.5 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. 1). During this warm-
ing 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.
5.6 Adjustment (only dealers authorised by KERN)
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). This
adjustment process must be carried out during the initial start-up, after change in
location and variation of surrounding temperature. To receive accurate measuring
values it is also recommended to adjust the balance periodically in weighing opera-
tion.
Use the adjustment weight (See Technical Data) to check and adjust the accuracy of
the balance at any time.
