10. Calibration
10.1 What is calibration?
Calibration is required to accurately weigh items with an electronic balance. Calibration should be per-
formed:
• When the location of the balance is changed, even within the same room.
• When the room temperature changes considerably.
• 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.
Caution
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 mech-
anism.
