Data Logger Function 

4.4.1

 

General Information 

Data Logger is intended for automation of the procedure of recording the measurement results. 
The memory capacity allows to save up to 64 channel plans, up to 16 limit plans, up to 250 channel 
data logger pages with maximum number of channels. The Analyzer allows viewing the saved data 
off-line or by means of a computer (Section 4.8.2)

4.4.2

 

Channel Plan List 

In  the  main  selection  menu,  the  icon 

  corresponds  to  the  mode.  This  mode  allows 

performing all the operations with channel plans: viewing, editing, deleting, and creation of new 
pages. See the view of the screen in Figure 4.7. The table contains 2 columns. The first column is a
