8. ADJUSTMENT
In order to ensure the highest weighing accuracy, it is recommended to periodically introduce a
corrective factor of indications to balance memory, the said factor must be referred to a mass
standard. In other words, balance adjustment shall be performed from time to time.
Adjustment should be carried out:
•
Before the beginning of weighing procedure,
•
If long breaks between following measuring series occur,
Types of adjustment:
•
Internal automatic adjustment
•
Manual internal adjustment
•
Adjustment with an external weight of declared mass which cannot be modified or of any mass,
but not lower than 30% of maximum range.
CAUTION!
In case of verified balances (with an internal automatic adjustment system) only automatic internal
adjustment and manual internal adjustment are available. Remember to carry out the adjustment
process when there is no load on the pan! When the weighing pan is loaded, command <RANGE
EXCEEDED> is displayed. In such a case remove the load and restart the the adjustment process. Adjustment
process can be aborted if necessary by pressing button at any time during the process.
8.7. INTERNAL ADJUSTMENT
Internal adjustment is carried out by means of an internal adjustment weight. button, when

CAUTION! Adjustment procedure requires stable environmental conditions (no air drafts or ground vibrations).
The process must be carried out with an empty weighing pan.
8.8. EXTERNAL ADJUSTMENT
External adjustment is carried out by means of an external mass standard of specified accuracy class
and weight. Both, accuracy class and mass standard weight depend on balance type and max
capacity. The process takes semi-automatic form, successive stages are signalled with prompts.
CAUTION! External adjustment is possible for balances that are not a subject to conformity assessment
(verification).
Process stages:
•
Enter <Adjustment> submenu, next select “External adjustment” option,
•
“Remove weight” prompt is displayed.
•

mass, “Adjustment; Please wait…” prompt is displayed,
•
Upon completed start mass determination procedure “Put weight …” prompt is displayed along
with particular mass standard value.
•
Put the required weigh on a pan and press button,
•
Upon completed procedure “Remove weight” prompt is displayed.
