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 .)

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 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 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.

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.

“d” Value Actual Mass Displayed Mass

−0.3 3000g 2999.7(3200g/0.1g balance)

+0.21 400g 400.21(420g/0.01g balance)
