The information on our webpages about the 32.000 values is together for all our instruments R/Sxxxx series and it is memory capacity for all channels. DP is counted from temperature and humidity and is not stored in the logger's memory. In manuals you can find the information considering the number of channels. For S3120 (noncyclic) it is 16252 values for temperature and 16252 values for humidity. This values are max. If you will interrupt the logging and will start again, it will decrease the memory capacity about 16 values. Please send us an e-mail with the file. We will check why it shows memory full when there was just 10 828 values.
