6  Single tests 

6.1 

Selection of single test 

Single tests can be selected in the Main Single Tests 

menu or in Memory Organizer’s main and 

submenus.  It  is  possible  to  select  the  area group  and  two  different modes for  selecting  single 
tests. 
 
Options 

 

 

 

Area Group 

With  help  of  area groups  it  is  possible  to  limit 
the  offered  single  tests.  The  instrument  has 
four area groups: 

 

the Portable appliances group

 

 

the Electrical machines group

 

 

the Switchgears group

 

 

the Welding equipment group

 

 

In the All group all measurements are offered.

 

 

 

 

Last used 

Up to the last 9 different executed single tests 
are displayed. 

 

 

 

Groups 

The  single  tests  are  divided  into  groups  of 
similar tests.
