6.6 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each display unit with connected weighing plate 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.
Provide adjustment weight.
The required adjustment weight depends on the capacity of the
weighing system. Carry out adjustment as near as possible to the
scale’s maximum weight. Info about test weights can be found on the
Internet at: http://www.kern-sohn.com
Observe stable environmental conditions. Stabilisation requires a certain
warm-up time.
How to carry out adjustment:

Start balance by pressing
ò

Press key and hold. “CAL” will appear briefly
followed by a flashing display of the value for an
adjustment weight
Here is an example of “30.000 kg”
(You can select the size of an adjustment weight in the
menu under menu item “CAL”.)

Place the adjustment weight in the centre of the
weighing plate and press to confirm.
“CAL F” will appear before the weighing scale changes to
weighing mode.
Adjustment has now been completed successfully.
An error during adjustment or the use of an incorrect adjusting weight will result
in an error message „CAL E“. Repeat adjustment.
