Adjustment - KERN EFS Series Operating Instructions Manual

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 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 balance
periodically in weighing operation.
With an adjustment weight, the weighing accuracy can be checked and re-adjusted at
any time.
Procedure when adjusting:
Observe stable environmental conditions. Stabilisation requires a certain warm-up
time.
Start balance by
Press long time until „unit" appears.
Press again, „cALE" appears
Press , "Zero" followed by the required adjustment
weight, will appear
After that „PutLd" is displayed.
Place adjustment weight. „Wait", followed by „reMLd" is
displayed. During the display „rEMld" take away the
adjustment weight.
The balance changes automatically into weighing mode.
Adjustment has now been completed successfully.
If an adjustment error occurs or a wrong adjustment weight is placed, „WronG" is
displayed. Repeat adjustment.
Keep the adjustment weight close to the balance. Daily control of the weighing
exactness is recommended for quality-relevant applications.
