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 if the logger is actively logging,

dormant or set to start at a given time.  It will also show the status of the logger's capacity. 

The Status subsections are 

Sampling

 and 

Memory

.

1.2.1.1

Logger Sampling

The sample rate is the frequency with which a logger stores readings to memory.  The

Sampling subsection indicates what the sample rate is.  In normal sampling, the rates

available are from once every 8 seconds to once every 34 minutes.  

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 A

Sample Rates

.

The Mode is the way the logger stores the data. The Average method stores an averaged

reading of the data read every 8 seconds over the sample interval you have chosen if the

sampling mode is set to Average (this does not apply to a sampling interval of 8 seconds). The

Spot method  still takes readings every 8 seconds but only stores the reading taken at the

selected interval.
