A.3 SERVICE CALIBRATION
Span calibration from the service menu allows you to set a new zero and maximum setting.
This is distinct from user level span calibration, which allows a user to adjust the zero and
maximum setting within the range established by the service menu span setting.
Remove any load from the Pan, including sample pan. Analyzer must be
OFF but plugged in.
Have 100g and 50g calibration masses available.
