Calibration module shield and protection method

A calibration system, comprising:

• an electronic calibration module;
• a terminal module interlocking with the calibration module such that a terminal connection board provides access to and permits write protection of calibration parameters stored in the calibration module when appropriately configured;
• a primary cover including a connection device, an access opening and a first through hole, the primary cover being configured to cover and exclude access to at least a portion of the terminal connection board where calibration controls are located, the access opening being located adjacent to the connection device to permit access to the portion of the terminal connection board when securing the primary cover over the underlying area;
• a shield configured to fit over the primary cover and prevent access to the access opening, the shield including a latch portion configured to latch on a first end portion of the primary cover and a second through hole located at a second end portion opposite the first end portion and corresponding to the first through hole of the primary cover;
• and
• a security mechanism configured to be received in the first and second through holes such that the security mechanism needs to be destroyed prior to access the portion of the terminal connection board.

A method for preventing access to write protected calibration parameters, comprising:

• eliminating access to an underlying area where calibration controls are located by installing a primary cover including a connection device and an access opening which permits access to the underlying area when securing the primary cover over the underlying area;
• securing the primary cover using the connection device by accessing the underlying layer through the access opening;
• placing a shield configured to fit over the primary cover to prevent access to the access opening, the shield including a latch portion configured to latch on a first end portion of the primary cover;
• and
• sealing the primary cover and the shield with a security mechanism which passes through a first through formed in the primary cover and a second through hole formed in the shield at a corresponding location such that the security mechanism needs to be overcome to access the underlying area.
