Last Automeasured
(page 17). When a logger is communicating with the radar, it can ask the radar to make a new measurement.
However, the logger then has to wait for the radar to complete the measurement.
If the user desires data that is instantly available, the radar can provide the last measured data. The radar

However, the logger then has to wait for the radar to complete the measurement.
If the user desires data that is instantly available, the radar can provide the last measured data. The radar
automatically measures based on the
interval (see page 16) . That data can be retrieved as the
last measured data.
For example, if radar is setup to automeasure every 10 minutes, with an averaging time of 10 seconds:
For example, if radar is setup to automeasure every 10 minutes, with an averaging time of 10 seconds:

Discharge is a measurement of water volume flowing over time. Please refer to the

Logging
A secure flash chip in the radar provides a logging capacity of more than 300,000 entries. Data will not be
lost if power is removed. There is not a means of erasing data from the log. Once the log is full, the oldest
data will be overwritten.
Each log entry consists of
lost if power is removed. There is not a means of erasing data from the log. Once the log is full, the oldest
data will be overwritten.
Each log entry consists of
date and time (with a second resolution)
name of the logged entry
measurement reading (optional)
measurement quality and units (optional)
The format of logged data is the Sutron Standard CSV format which was introduced in the Summer of 2009.
It is a format common to current Sutron products.
The general format specification for Sutron Standard CSV format is
mm/dd/yyyy,hh:mm:ss,label,data[,units,qual][,label,data[,units,qual]]
Here are several examples of log entries:
01/19/2010,09:21:49,Reset Powerup,1
01/19/2010,09:30:00,Stage,1.25,feet
01/19/2010,09:45:00,Stage,1.27,feet

Minimally, radar will log stage and various events. The user can decide how often to log stage (via
