6.4 Battery operation FKB
 To insert the batteries (6 x 1.5 V) remove the battery compartment cover. Remove it
with the help of a coin.
 In the each battery tube insert three batteries in the same polarity sense.
 Screw down again the battery cover.
To save the battery, the background illumination can be switched off (see chap. 7.3).
Moreover the AUTO-OFF function can be activated (see chap. 7.2.10).
If the battery voltage drops below a critical value for operational safety, this will be indicat-
ed in the display with the “BATT LOW“ information.
6.5 Connecting peripheral equipment
The balance must be disconnected from the mains before connecting or disconnecting
additional equipment (printer, PC) to or from the data interface.
Only use KERN accessories and peripheral equipment with your balance. These have
been ideally coordinated to your balance.
6.6 Initial start-up
A warm-up time of 2 hours stabilises the measured values after switching on.
The accuracy of the balance depends on the local acceleration of the fall.
Please be sure to observe the information in the chapter on adjusting.
6.7 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 prin-
ciple - 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 sur-
rounding temperature. It is also recommendable to adjust the balance periodically during
weighing operation in order to obtain exact measured values.
