6.5 Connecting peripheral equipment
The balance must be disconnected from the mains before connecting or disconnect-
ing 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 5 minutes 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 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 lo-
cation and variation of surrounding temperature. It is also recommendable to adjust
the balance periodically during weighing operation in order to obtain exact measured
values.
6.8 Adjusting
Using a precision weight, the accuracy of the balance can be checked at any time
and adjusted.
Adjustment procedure:
Check that the surrounding conditions are stable.
A short warm-up time of about 5 minutes are recommended for stabilisation.
Switch the balance on by pressing the key, then wait until “0“ is indicated.
Press the key and hold. After the acoustic signal is heard “CAL“ will appear on
the display for a brief period. The exact size of the selected adjusting weight flashes
on the display following this (capture 8.3 „Select the adjusting weight“). Now place
the adjusting weight in the middle of the weighing plate.
Now operate the key. Shortly after “CAL F“ appears, and then the automatic re-
turn to the normal weighing mode will follow. On the display the weight of the adjust-
ing weight appears.
In case of an adjusting error or a wrong adjusting weight “CAL E“ will appear. Repeat
the adjusting procedure.
Keep the adjusting weight near the balance. Daily verification of the balance accu-
racy is recommended for quality assured applications.
