7.20 Field Calibration Adjustment
The Field Calibration Adjustment permits
the end user to "shift" the calibration curve
to provide better accuracy when the Factory
Standard Calibration is not suitable. Each
step on the Field Calibration Adjustment
will increase (clockwise) or decrease
(counterclockwise) the displayed value
by 1.5%.
Increase: [7 steps] x [1 .5% per step] = +10.5%
Decrease: [7 steps] x [1.5% per step] = –10.5%
If a Field Adjustment Calibration is not adequate, the accuracy of the DTMB
can be increased further by ordering a Special Calibration using a calibration
sample supplied by the user. Refer to Special Calibration, Section 7.30.
7.20 LCD Display Indications and Error Codes
7.21 Over Range Display
When a displayed value is flashing on & off, this
indicates that this reading is higher than the
maximum range of the unit. The accuracy of the
flashing value is not guaranteed. When all F’s are
displayed, this indicates that the current value
greatly exceeds the maximum range of the unit.
7.22 Error Codes
If the Error Code “E009” is displayed, try turning
the power on and off a few times to clear it. If it
does not clear, contact the factory. If the Error
Code “E001” is displayed, the user is attempting
to store date with units (g or lb.) different than
those values already stored in memory. Clear the
data stored in memory and start again.
