Important and common terms 

The Commander-3 can be operated in two different user modes (see page 23):  

 

Easy mode 

 

Professional mode 

You can switch between these modes in system settings menu (see page 25). 

These two values are identified each time a noise logger performs a measurement:  

 

“Level” 

…  is the noise level (volume) of a measurement 

 

“Frequency”  …  is the frequency in the measurement’s frequency spectrum with 

the greatest deflection 

 

ESA stands for “Extended Spectral Analysis” and means that noise level and frequency 
are combined in one reading using a mathematical formula. This results in an extended 
view  of  the  measured  data,  which  makes  the  leak  probability  and  position  visible  in 
relation to other loggers. The dimensionless ESA value can be between 0 and 100. The 
higher the ESA value, the higher the leak probability and the shorter the distance from 
the logger to the leak. 

In  order  to  analyse  the  recorded  measurements,  the  noise  loggers  must  be  read  after 
measuring,  i.e.  the  data  in  the  loggers  is  accessed  wirelessly  with  a  reading  device 
(Commander/Reader/PC). It is possible to do this in the following ways: 

 

Group mode 

 

 

 

 

 

 

 

 

 

 

 

 

 

“Lift&Shift” 

“Patrol” 

“Network” 

The loggers are collected; 

data is read out wirelessly  
in the office 

The loggers remain at  
the place of use; 

data is read out  
wirelessly while  
“driving by” 

All the installed loggers 
are networked with each 
other and connected to 
a GSM box; 

data is read out via 
mobile radio from the 
office 

 

The method  must  be  chosen  for  reading  out  the  measured  data  before  the  measuring 
work is performed. Before measuring, the mode decided on is permanently assigned to 
the  loggers  or  logger  groups.  After  that,  only  loggers  that  have  been  configured  for 
reading using “Patrol” can be read with “Patrol”, for example, and not with “Lift&Shift” or 
“Network”. The same applies to the other group modes.  

User mode 

Level and frequency 

ESA value 

Group mode
