L900 MIU Pit and Wall Installation and Maintenance Guide 35Chapter 6: Data Logging ExtractionAbout Data LoggingThe L900 MIU is capable of storing interval data for data logging. The L900 MIUis activated using the Trimble®Nomad®and R900®Belt Clip Transceiver(R900 BCT) and is explained in more detail in the following section.The L900 MIU stores consumption in hourly intervals for a rolling total of 96 days.This is equal to 2,304 hourly intervals of consumption. The data logging data isextracted through RF activation. The RF activation allows the utility workers tovisit the location and extract the data without physically interacting with the meteritself. This limits the worker’s exposure to animals or other dangerous situations.The extraction process, once started, takes approximately 30 seconds. Theactivation is done through the HHU connected to the R900 BCT via Bluetooth.The activation signal is sent by the R900 BCT to the L900 MIU which in turnsends the data intervals to the R900 BCT and are saved in the HHU.Accessing Data LoggingComplete the following steps for data logging.1.
