A method for maintaining a medical device in a sterile atmosphere at a desired temperature during a calibration step is provided. The method includes packaging a medical device and temperature indicator in a sterile container such that the indicator is visible to a user. Next, heat can be applied to the container in order to stabilize the temperature of the container (as indicated by the encased temperature indicator) at room temperature. Once at room temperature, the device can be calibrated while remaining in the sterile atmosphere. A kit including such a container and a set of instructions is also provided. Like above, the container of the kit can include a sterile medical device and temperature indicator such that the device can be maintained in a sterile environment during calibration and/or zeroing. As such, the method and kit allow for increased precision and safety in performing medical procedures.
