10. Calibration
10.1 What is calibration?
Calibration is required to accurately weigh items with an electronic balance. Calibration
should be performed:
x When the location of the balance is changed, even within the same room.
x When the room temperature changes considerably.
x Periodically, according to the quality control plan of the user.
Terms used in this manual:
Span Calibration: Adjustment of the balance to specifications using two
weight values; zero and an appropriate value for the
balance capacity.
Calibration Check: Comparing the current calibration weight reading to the
calibration weight reading after the last span calibration.
Calibration: Pertains to both span calibration and calibration check.
Never plug off the balance when the following messages are displayed.
“i-CAL x”, “i-tESt x”, “wAit”, “Abort”, “CAL E x”(“x” represents a number).
With UW series, displaced built-in weight may cause damage to the mechanism.
