Systems and methods for calibrating a load cell of a disk burnishing machine

A system for performing in situ testing of a load cell of a disk burnishing machine, the system comprising:

• the disk burnishing machine configured to burnish a disk, the disk burnishing machine comprising:
• a load cell bracket attached to a component of the disk burnishing machine;
• and
• wherein the load cell is mounted within the load cell bracket and comprises a force measuring surface, and
• wherein the load cell bracket is configured to be oriented such that the force measuring surface of the load cell faces a direction that is about opposite to a direction of gravity;
• a preselected weight;
• and
• a weight holder configured to receive the preselected weight, wherein the weight holder is configured to be mounted to the load cell bracket and to be aligned with the load cell,
• wherein the preselected weight is configured to be positioned within the weight holder and on the force measuring surface of the load cell.
