6.1.3 Log Buffer
6.1.3.1 Buffer
Open the Log Buffer window by clicking on the Log Buffer icon.
The Log Buffer window is where you set up the logger memory for recording data by selecting what
to log and how often to log it. Data loggers have one Main Buffer and multiple Event Buffers.
Event Buffers tend to be small and are used to store data logged on an ad-hoc basis. Whatever
memory is not allocated to Event Buffers is allocated to the Main Buffer. Since Event Buffers
default to zero bytes, the default Main Buffer size is all the available memory.
6.1.3.2 Instrument Channels
Each Buffer has its own set of the Instrument Channel checkboxes. You control which of the
available channels gets logged into each buffer. The following channel logging options are
available; however, some instrument channels may not support all of them (for example,
temperature cannot be totalised)
Option Description
RAW
The instantaneous value of the channel at the time of the log.
MIN
The minimum of the values sampled at each scan over the
log interval
MAX
The maximum of the values sampled at each scan over the
log interval
TOT
The total of the values sampled at each scan over the
log interval
AVG
The average (arithmetic mean) of the values sampled at each scan over the
log interval
avg
The average (arithmetic mean) of the values sampled at each scan over the
sub interval
