Adjustment; Adjustment With External Weight (Only Pes) - KERN pej Betriebsanleitung

6.9.

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 at every commissioning, after each change
of location as well as in case of fluctuating environment temperature. To receive ac-
curate measuring values it is also recommended to adjust the balance periodically in
weighing operation.

6.9.1. Adjustment with external weight (only PES)

Adjustment should be carried out with the recommended adjusting weight (see
Chapter 1 „Technical Data"). The adjustment can also be carried out with different
adjusting weights (see table), but not ideal from a metrological point of view.

Procedure when adjusting:
Observe stable environment conditions. A warming-up time of ca. 30 minutes for
stabilisation is necessary. Ensure that there are no objects on the weighing plate.
At verified balances, the adjustment is locked by a switch (except accuracy class I).
In order to adjust, open the locking switch see chap.6.10.1 (except accuracy class I).
