About Data Logging
The L900 MIU is capable of storing interval data for data logging. The L900 MIU
is 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 is
extracted through RF activation. The RF activation allows the utility workers to
visit the location and extract the data without physically interacting with the meter
itself. This limits the worker’s exposure to animals or other dangerous situations.
The extraction process, once started, takes approximately 30 seconds. The
activation 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 turn
sends the data intervals to the R900 BCT and are saved in the HHU.
Accessing Data Logging
Complete the following steps for data logging.
1. From the host software home screen on the HHU, click MENU. See Figure 46.
