Calibration Check Using the Built-in Weight (UW Series Only)
1
Verify that the balance is in mass display and
that the pan is empty.
2
Press the
[CAL]
key once to display “i-tESt”.
(If “i-tESt” is not displayed, return to mass display
and select menu item
.)
3
Press the
[O/T]
key.
The display changes sequentially from “i-tESt 2”
to the “d xxx” display. (xxx indicates a numeric
value)
This “d” value indicates the difference between
the current calibration weight reading and the cal-
ibration weight reading at the last span calibra-
tion.
4
To perform span calibration, change the “d”
value to zero, by pressing the
[CAL]
key.
--Otherwise, Press the
[O/T]
key to avoid chang-
ing the “d” value to zero. (Pressing the
[POWER]
key interrupts calibration and does not change
this value to zero.)
“CALEnd” is displayed, indicating the completion
of the calibration check.
2
Note
Changing the “d” value to zero is equivalent to performing span calibration.
Notes
• Examples for interpreting the results of a Calibration Check:
• Error codes that may be displayed:
“d ouEr” (d OVER) indicates that the “d” value is 1000 counts or more.
“d UndEr” indicates that the “d” value is -1000 counts or less.
