To adjust the load display on a Minebea CSD-581-15, follow these steps:

1. Press the “FUNC.” key for about one second. The display will show “FUNC”.
2. Press the “A/ZA” key multiple times to cycle through modes: “FUNC” → “CCAL” → “ACAL” → “LCAL” → “ZERO” → “SPAN” → “TARE” → “CHECK” → “MONIT” → “F−END” → back to “FUNC”.
3. To adjust zero (fine adjustment):
- Stop at “ZERO”, press “ENTER”.
- Use “A/ZA” or “A/ZOFFY” keys to set the current load value to zero.
- Press “ENTER” again to save and exit. Display will show “T−END”.
4. To adjust span (fine adjustment):
- Ensure tare weight cancellation (A/Z) and zero tracking are not active.
- Enter span fine mode through the same function sequence.
- Set the actual load value applied to the load cell using “A/ZA”, “A/ZOFFY”, or “CHECK” keys.
- Press “ENTER” to confirm.

Make sure the load value is within the display range (−10% to +110% of the maximum display value). If below or above this range, the display will show “−OL” or “OL”.
