ABSTRACT:
An apparatus and method for preventing access to calibration controls includes a primary cover including a connection device, an access opening and a first through hole. The primary cover is configured to exclude access to an underlying area. The access opening is located on the primary cover to permit access to the underlying area when securing the primary cover. A shield is configured to fit over the primary cover and prevent access to the access opening. The shield includes 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 and corresponding to the first through hole of the primary cover. A security mechanism is configured to be received in the first and second through holes such that the security mechanism shows signs of tampering when unauthorized access to the underlying area is attempted.
