  • Page 50: Offset Adjustment

    INT5 User Manual 5.5. Offset Adjustment After you have calibrated your meter, you can use the 'OF.St' feature to make fine additions or subtractions to the reading, without affecting the calibration itself. For example if your weighing structure is altered after calibration and you want to subtract the effect of 37kg of extra metalwork which was welded to the hopper, you can easily do this by entering a value of -37 in the offset value.

  • Page 51: Scale Factor Adjustment

    INT5 User Manual 5.6. Scale Factor Adjustment After you have calibrated your meter, you can use the 'SCAL' feature to make fine adjustments to calibration, without affecting the calibration itself, or you can convert to different units of measure. Examples:...
