Note:
In order to terminate internal calibration process in balances that do not comply with verification
requirements press
key and wait until balance mechanism is settled in initial position.
11. Checking the balance
In order to confirm correctness of the balance during its operation, before starting and after finishing
every measurement series it is advised to check weighing accuracy. It can be done by weighing external
calibration weight or other object with exactly known mass.
If exceeding of allowable measurement error is affirmed, the following things should be checked:
-
if the balance stands stable and it is levelled,
-
if the balance is exposed on rapid air blasts, vibrations, rapid temperature changes or air
humidity,
-
if the balance is not affected directly by heat source, electromagnetic radiation or magnetic field.
The cause of inaccuracy can be too low temperature of the balance as well, when it was unplugged from
power supply. In this situation leave the balance switched on for several minutes in order to adjust its
internal temperature.
If none of above causes of inaccuracy occurs, calibration with external weight should be performed to the
balance. Recommended external calibration weight (to buy for additional charge) is given in technical
data table. In order to calibrate the balance with external weight in legally verified balances verification
seals should be removed and another legal verification should be performed. In this case it is
recommended to contact authorized service centre.
Calibration with external weight is described in details in chapter 17.1.
