Adjustment; Kern Hum - KERN HUS Series Instruction Manual

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.
Carry out adjustment as close as possible to the maximum load of the scales, see
chap. 1 „Technical data". Weights providing different nominal values can be used but
from a metrological point of view this is not ideal. For admissible adjustment weights
see table 1.

Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization.
 Switch-off balance and attach a carrying help if necessary.
 Press and hold ZERO- and MODE whilst at the same time switching on the
scales with the carrying aid attached. Release keys, „CAL?" will be displayed.
