Congratulations on your purchase of the XC880A High Accuracy Parts Counting
Scale. Since 1962, Sterling Scale Co. has been manufacturing quality scales and
weighing systems for industry. All Sterling Scale models are covered by a full one-year
limited warranty against defects in materials and workmanship. Ask your dealer, or
contact Sterling Scale Co. for warranty details.
1.1 Unpacking and Assembly
This section will describe the proper unpacking and assembly of your new XC880A
High Accuracy igital Weigh Scale. These instructions should be followed to avoid
damage to the load cell, or electronics. This section only applies to desk top versions of
the XC880A.
1. Remove the XC880A from the shipping container. The package should contain
the following items. Contact your dealer or Sterling Scale Co. if any items are
missing:
•This Users Manual on C .
