7.7 Connection of peripheral devices

Before connecting or disconnecting of additional devices (printer, PC) to the data
interface, always disconnect the balance from the power supply.
With your balance, only use accessories and peripheral devices by KERN, as they are
ideally tuned to your balance.

7.8 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).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.

7.9 Adjustment

As the acceleration value due to gravity is not the same at every location on earth, each
display unit with connected weighing pan 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 weighing system has not already been adjusted to the
location in the factory). This adjustment process must be carried out for the first
commissioning, after each change of location as well as in case of fluctuating
environment temperature. To receive accurate measuring values it is also
recommended to adjust the display unit periodically in weighing operation.
•
Arrange the required adjustment weight, see chap. 1.
Carry out adjustment as near as possible to the highest load of the balance
(recommended adjustment weight see chap. 1). Weights of different nominal
values or tolerance classes may be used for adjustment but are not optimal
for technical measuring. The accuracy of the adjustment weight must
correspond approximately to or, if possible, be better than, the readability [d]
of the balance. Info about test weights can be found on the Internet at:

Observe stable environmental conditions. A warming up time (see chapter 1)
is required for stabilization.
•
Ensure that there are no objects on the weighing pan.
