SmartReader Data Loggers

1.2.1 Logger Status

When you contact the logger, the logger status is displayed. The Status line indicates whether

the data logger is actively logging, waiting to start or dormant. If you set up the logger with no

delay, it will immediately start logging and the status will show the number of readings, or

samples, that have been taken. If you want to have the logger wait before it starts logging, set

the start time accordingly. The Status subsections are Sampling and Memory.

1.2.1.1 Logger Sampling

The Sampling subsection indicates the sample rate, which is the frequency with which a logger

takes readings. The rates available are from once every 8 seconds to once every 5 days.

To set the sample rate, click on the desired time unit and select the value from the drop-down

list as shown.

To find out more about sample rates and to view a set of sample rate tables, see Appendix D

Sample Rates.

1.2.1.2 Logger Memory

The Memory subsection indicates how the data is stored in memory and what the start and

end times (or capacity) are for the data logging. In the FIFO (First In, First Out) mode, the

logger continually stores data and when the memory limit is reached, the new readings start to

overwrite the oldest readings. In this method, the logger is always collecting data, but only

saves the most recent data in its memory. In the Stop When Full mode, when the memory

limit is reached, the logger stops recording.
