The Android app included with the MAXREFDES73# measures and displays temperature as well as galvanic skin response (GSR) versus both time and frequency. To save the data, click on the three vertical dots on the upper right-hand corner of the app screen: You will be presented with an option for saving the data in a CSV file on your Android device. The software is limited to saving 15000 samples, provided enough storage space is available on your Android device. One reading is taken every second, meaning that up to 15000 seconds, or over 4 hours of data can be saved. The data is saved as "maxrefdes73.csv" in the root directory of your Android phone. Any subsequent saves will append the new data to the existing file.
