Adjustment - KERN CME 100-3 Operating Instruction

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, chap. 8.4.4), 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.
Turn on balance by pressing the ON/OFF key
Press and keep holding down the
at the same time. Keep pressing both keys for 3 s until the display is
extinguished.
Let go of both keys. "CAL" appears. After that the exact size appears flashing
in the display (chapter 8.4.4) of the adjustment weight. Now set the adjusting
weight in the centre of the weighing plate.
Confirm by pressing the PRINT key Short time later appears „CAL F", then
return automatically to 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.
