In one embodiment of the invention, a method includes receiving an input terminal change request, requesting that a current input terminal be changed from a first input terminal to a second input terminal. The method may further include determining if an external device is connected to the second input terminal. In one embodiment of the invention, the second input terminal includes a connection detection switch. The method may also include switching to the second input terminal when the connection detection switch indicates an external device connection and skipping the second input terminal when the connection detection switch indicates no external device connected according to one embodiment of the invention.

Abstract: An isolator includes: a working chamber for conducting work on cells, the working chamber including an opening on a front face thereof; a transparent plate member, made of a resin, through which an interior of the working chamber can be viewed, the plate member being mounted to the working chamber so as to close the opening; and a working chamber sterilization device configured to sterilize the interior of the working chamber by supplying hydrogen peroxide gas into the working chamber, and thereafter discharge the hydrogen peroxide gas in the working chamber, the plate member having at least a face, facing the working chamber, formed to have a water absorption rate equal to or smaller than a predetermined value.
