Adjustment - KERN EMS Series Instruction Manual

5.7 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 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.
5.8 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.
 Turn on balance by pressing the ON/OFF key.
 Press the MODE key and keep it pressed, in the display appears shortly
„CAL". After that the exact size appears flashing in the display of the
adjustment weight.
 Now set the adjusting weight in the centre of the weighing plate.
 Press the SET key. Short time later there appears „CAL F", then the automatic
return to the 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.
