Interval (Hours)
Enter this menu to set hours for the balance to start
Internal Calibration (AutoCal
™).
The value can be set from 3-11 hours.
5.3.5
AutoCal
™ Adjustment
Use this calibration method to adjust the zero calibration point, without affecting the span or linearity
calibration.
Calibration Adjust may be used to adjust the result of the Internal calibration by +100 divisions.
Note:
Before making a calibration adjustment, perform an Internal Calibration. To verify whether an
adjustment is needed, place a test mass equal to the
span calibration value
*
on the pan and note the
difference (in divisions) between the nominal mass value and the actual Balance reading. If the difference
is 1 division, calibration adjustment is not required. If the difference e1 division,
calibration adjustment is recommended. (
*
See Table 5-1, below.
)
Example:
Actual weight reading:
200.014
Expected weight reading:
200.000 (Test mass value)
Difference Weight (d):
0.014
Difference weight in digits:
–14 (Adjust value)
To perform a Calibration Adjustment, touch AutoCal Adjustment from the Calibration Menu; Enter the
value (positive or negative divisions) to match the difference noted earlier in the procedure and press
.
Recalibrate using Internal Calibration. After calibration, place the test mass on the pan and verify that the
mass value now matches the displayed value. If not, repeat the procedure until Internal Calibration
reading agrees with the test mass.
Once completed, the balance stores the Adjustment value and the display returns to the current
application.
5.3.6
Span Calibration
Span calibration uses two calibration points, one at zero load and the other at specified full load (span).
Refer to Table 5.1 for Span values. For detailed calibration mass information please see the specification
tables in section 9.

Factory default settings are shown in bold.
