8.6.2 Zero and Span Adjustments
In this sub-block you can only perform zero adjustment or span adjustment automatically without
performing full calibration. Do not perform span calibration if eCal electronic calibration
Zero Adjustment
1. Press key at the [ 621 ZERO ADJUSTM ] prompt to start the zero adjustment.
2. At the [ UNLOAD THE PAN] prompt, remove any weight on the platform, then press key.
3. The terminal automatically starts to capture zero and the [ WAIT ] message appears during zero
adjustment.
Span Adjustment
1. Press key at the [ 622 SPAN ADJUSTM ] prompt to start the span adjustment.
2. At the [ LOAD THE SCALE] [ XXXXXX ] prompt, the test weight value will be used for the
calibration seen on the display. Enter the test weight value via keys. A minimum test load
requirement is 20% of scale capacity for accurate calibration; FLINTEC recommends test load
between 50% to 75% of the capacity.
3. Place the test weights on the scale.
4. Press to start span calibration. [ WAIT ] message will be shown on the display 10 seconds
during span calibration.
Span Adjustment under load
This parameter is being used to perform span adjustment of a scale without lifting the load on it. This
operation especially used for span adjustment tank / silo which have some material in it. You can make span
adjustment without emptying the tank.
1. Press key at the [ 623 S UNDER LOAD ] prompt to start the span adjustment under load.

temporary zero.
3. Press key and the display will show [ WAIT ] message during temporary zero adjustment.
4. At the [ LOAD THE SCALE ] [ XXXXXX ] prompt, the test weight value will be used for the
calibration is seen on the display. Enter the test weight value via keys. A minimum test load
requirement is 20% of scale capacity for accurate calibration. FLINTEC recommends test load
between 50% to 75% of the capacity. Sum of the preload of the scale and test weight must be
less than capacity.
5. Place the test weights on the scale.
6. Press to start span calibration. [ WAIT ] message will be shown on the display 10 seconds
during span calibration.
7. Zero adjustment is recommended after emptying the scale.
