10.2.2 Calibration Check Using the Built-in Weight (UW Series Only)
The shift from the last calibration is displayed using the built-in calibration weight, however,
the balance is not adjusted.
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
2
.)
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 calibration
weight reading at the last span calibration.
4
. To perform span calibration, change the “d”
value to zero, by pressing the
[CAL]
key.
--Otherwise, Press the
[O/T]
key to avoid changing
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.
Changing the “d” value to zero is equivalent to performing span calibration.

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.
