7. ADJUSTMENT
In order to ensure the highest measuring accuracy, it is recommended to periodically
introduce to balance memory a corrective factor of indications in relation to a mass
standard – i.e. balance adjustment.
Adjustment should be carried out:
-
Before the beginning of a weighing procedure,
-
If long breaks between following measuring series occur
-
If temperature inside the balance changes more than: 0,8
°
C
Types of adjustment
-
Internal automatic adjustment
* triggered by temperature change
* triggered by elapsing time
-
Manual internal adjustment
* initiated from balance’s keyboard
-
Adjustment with external weight
* with declared mass which cannot be modified
* with optional mass which needs to be specified before process initiation
(only in non-verified balances)
Caution:
In case of verified balances only the automatic internal adjustment and manual internal
adjustment systems are available for a user.
Remember to Perform the adjustment when there is no load on the pan!
7.1. Internal automatic adjustment
Activation of automatic internal adjustment is triggered on:
-
Elapsing a specified amount of time from last carried out adjustment
process, or
-
Ambient temperature changes by a value specified by the balance
manufacturer.
* in case of balance AS/X series it is 0,8
°
C,
On recognizing any of the above case, balance’s display shows the following message
box.
