BALANCE ADJUSTMENT
As the gravitational acceleration force has different value at various latitudes and
altitudes, a balance should be adjusted to present working conditions. This process
should take place at the first installation of the instrument on site and at its every re-
location – as in case of ambient temperature changes.
In order to ensure the highest weighing 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 weighing procedure,
-
If long breaks between following measuring series occur
-
If temperature inside the balance changes more than: 3
°
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.
CAUTION
In case of verified balances (with internal automatic adjustment system)
only the automatic internal adjustment and manual internal adjustment
system are available for a user.
Remember to carry out adjustment process only when there is no load on
the weighing pan! In case there is load on the weighing pan, the display
will indicate
a command
Er1 Hi
. It is comment of unloading the pan.
Adjustment process can be aborted if necessary by pressing Esc/TARE
key.

Internal adjustment
Adjustment process can be initiated automatically or manually.
Manual means of activating adjustment procedure is realized by pressing
CAL
key on balance’s keyboard. System of automatic adjustment will carry out the
process fully automatically inform the operator on successive process stages.
