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.
x Examples for interpreting the results of a Calibration Check:
“d” Value Actual Mass Displayed Mass
-0.3
+0.21
3000g
400g
2999.7(3200g/0.1g balance)
400.21(420g/0.01g balance)
x 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.
