Connection Of Peripheral Devices; Initial Commissioning; Adjustment; Verification - KERN FKA 30K-4 Mode D'emploi

5.6 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 acces-
sories and peripheral devices by KERN, as they are ideally tuned to your balance.

5.7 Initial Commissioning

A warming up time of 2 hours after switching on stabilizes the measuring values.
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter "Adjustment".

5.8 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). 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 operation.
5.9 Adjustment
With an adjustment weight, the weighing accuracy can be checked and re-adjusted at any
time.
Attention: In the verified balances the adjustment is not possible.
Procedure when adjusting:
Observe stable environmental conditions. A short warming up time of ca. 15 minutes is rec-
ommended for stabilization.

5.10 Verification

General introduction:
According to EU directive 90/384/EEC balances must be verified if they are used as follows
(legally controlled area):
a) For commercial transactions if the price of goods is determined by weighing.
b) For the production of medicines in pharmacies as well as for analyses in the medical
and pharmaceutical laboratory.
c) For official purposes
d) For manufacturing final packages
In cases of doubt, please contact your local trade in standard.
Verification instructions
An EU type approval exists for balances described in their technical data as verifiable. If a
balance is used where obligation to verify exists as described above, it must verified and re-
verified in regular intervals.
Re-verification of a balance is carried out according to the respective national regulations.
The validity for verification of balances in Germany is e.g. 2 years.
The legal regulation of the country where the balance is used must be observed!
