Logging
Satlink automatically logs the sensor data that it collects (see
). Data is logged on
secure flash memory with a capacity of over 1,000,000 entries.
Measurement readings are logged according to the
Logging Interval
(see
). Each measurement has its own logging interval.
Logged data will
not
be lost if power is removed. Once the log is full, the oldest data will
be overwritten.
Only logged data may be transmitted.
Satlink logs events such as power up, log download, and setup change.
When downloaded, the data is presented in Sutron Standard CSV format. It is a format common
to current Sutron products. A log entry looks like this:
04/02/2012,09:25:00,STAGE,20.50,FT,G
date and time (with a one-second resolution)
user set measurement label (STAGE)
measurement reading (20.50)
user set measurement units (FT)
measurement quality (G = good, B = bad)
The general format specification for Sutron Standard CSV format is:
mm/dd/yyyy,hh:mm:ss,label,data,units,quality
Here are some examples of log entries:
01/19/2015,09:30:00,Stage,1.25,ft,G
01/19/2015,09:45:00,Stage,1.27,ft,G
01/19/2015,09:50:27,Setup Change,,G
To help preserve data integrity and reliability, there is no way to erase data from the log.

Downloading the Log
Logged data can be downloaded using LinkComm or via a terminal program using the LOG
command. Additionally, plugging in a USB thumb drive into Satlink will automatically download
the log.
The downloaded data is in Sutron Standard CSV format and can be easily displayed using Sutron’s
GRAPHER program (downloadable from
) or common spreadsheet/word
processing programs.
