The activated monitor must be placed immediately in its predetermined location. As described in the SOP, or otherwise it is recommended to place the device as close to the supervised goods as possible. This is an important prerequisite to ensure the temperatures observed by the device are as close to the product temperature as possible.
Important: It is recommended to “precondition” the device to the desired mean temperature for about 30 minutes before use, especially if no start delay time has been programmed. This is to ensure against false readings during start-up.
