Initial Commissioning; Adjustment - KERN DE3K1N Operating Manual

6.6 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.

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
location and variation of surrounding temperature. To receive accurate measuring
values it is also recommended to adjust the balance periodically in weighing
operation.
6.8 Adjustment
The adjustment should be made with the recommended adjustment weight (see
chap. 1 "Technical data"). Adjustment is also possible with the weights of other
nominal values (see table 1), but not the optimum for measuring technique.
Procedure when adjusting:
Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization.
Switch on the balance using the
Press key and keep it pressed, after the acoustic signal appears in the display for
short time „CAL". After that the exact size appears flashing in the display
(chapter.8.4) of the adjustment weight.
Now set the adjusting weight in the centre of the weighing plate.
Now press the
the normal weighing mode. In the display there appears the value of the adjustment
weight.
An error during adjustment or the use of an incorrect adjusting weight will result in an
error message „CAL E". Repeat adjustment.
Keep the adjustment close to the balance. Daily control of the weighing exactness is
recommended for quality-relevant applications.
