7.5.2 [ CAL ] Calibration
Calibration consists of two adjustments: zero adjustment and span adjustment.
For linearization of a scale press ► key.
Calibration is performed as;
1. Press Enter to start the calibration.
2. At the [ UnLoAd ] prompt, unload the scale then press Enter .
3. The indicator automatically starts to capture zero and the [ - - - ] message indicates the operation
is in progress.
4. After a while the [ LoAd ] prompt appears with a suggested test weight on the display as
[ XXXXXX ]. For definition of different test weight use the navigation keys.
FLINTEC recommends using between 50 and 100% of the scale capacity but minimum 20%.
An insufficient weight leads to a calibration error.
5. Place the test weights or another practical weight on the scale.
6. Press Enter to start span calibration. [ - - - ] message appears on the display while span
calibration is being performed.
7. After the calibration the Linearity Correction can be executed.
7.5.3 [ LınCAL ] Linearity Correction
Three steps calibration will improve the performance of the scale.
If you will not perform linearity correction press ► key or press Esc key to return to the main
block.
Linearity correction is performed as;
1. Press Enter prompt to start three-point calibration.
2. At the [ UnLoAd ] prompt, remove any weight on the platform, then press Enter .
3. The indicator automatically starts to capture zero and the [ - - - ] message indicates the operation
is in progress.
4. After a while the [ Load 1 ] prompt appears with a suggested test weight on the display as
[ XXXXXX ]. This load shall be between 35% and 65% of the scale’s capacity. Enter the Load 1
value using navigation keys.
5. Load the scale.
6. Press Enter to start the span calibration at Load 1. [ - - - ] message indicates the operation is in
progress.
7. At the [ Load 2 ] prompt, the second load will be suggested as [ XXXXXX ]. For definition of
different test weight use the navigation keys. Load 2 weight shall be between 90% and 100% of
the scale capacity.
8. Place the test weights or another practical weight on the scale.
9. Press Enter to start second step span calibration. [ - - - ] message appears on the display.
10. The next item Zero Adjustment prompt appears after the linearization.
7.5.4 Zero and Span Adjustment
[ ZerAdJ ] Zero Adjustment
This parameter is only being used for refreshing the zero level of the scale to prevent wrong weighing
from zero drifts.
If you will not perform Zero adjustment press ► key or press Esc key to return to the main block.
Zero adjustment is performed as;
1. Press Enter key to start the zero adjustment.
2. At the [ UnLoAd ] prompt, remove any weight from the platform, then press Enter .
3. The indicator automatically starts to capture zero and the [ - - - ] message indicates the operation
is in progress.
4. Next item appears on the display after the zero adjustment.
