Calibration and Adjustment
Background During calibration, a calibration weight is used to determine how much the
displayed value deviates from the actual measurement value. This deviation is
compared to a specified desired value. Adjustment eliminates this deviation or
reduces the permissible error limits.
For Secura
® , Quintix ® , and Practum ® models, calibration and adjustment are
combined as one process. The balance is automatically adjusted after each
calibration.
Before using a verified balance for legal metrology, calibration/adjustment must
always be carried out at the balance placement station. This can be performed
automatically or manually. Practum
® models with accuracy class (I) can be
calibrated using an external weight.
When and How Often To achieve the highest accuracy possible, regularly calibrate and adjust the balance:
– daily after switching on the balance,
– each time the balance is leveled,
– each time ambient conditions have changed (temperature, humidity, or air
pressure),
– each time the balance is set up at a new placement station or moved on its
current station.
The following describes in detail the available options for calibrating and adjusting
the balance:
– Calibration/Adjustment using an internal calibration weight (Secura
® and
Quintix ® only)
– Calibration/Adjustment using an external calibration weight
– Automatic calibration/adjustment with isoCAL
