A testing system and methods for using the same are provided. The testing system can include a sensor and a radiofrequency (RF) tag mounted on the sensor. The RF tag can be configured to store sensor information regarding the sensor and to wirelessly communicate at least a portion of the sensor information to a portable computing device upon request. The portable computing device can be configured to allow an operator to obtain selected sensor information from the RF tag and display it on the portable computing device. The portable computing device can also be configured to retrieve additional sensor information from external sources, such as a sensor manufacturer, via a network. Thus, sensor information can be retrieved in the field by the portable computing device for use in operating the testing system.
