16.1 Creating Distributor Structures, General
A complete distributor structure with data for electrical circuits 
and RCDs can be created in the PROFITEST MASTER test instru-
ment. 
This structure makes it possible to assign measurements to the 
electrical circuits of various distributors, buildings and customers.
There are two possible procedures:
• On location or at the 
construction site: 
Create the distributor 
structure in the test 
instrument. 
A distributor struc-
ture with up to 
50,000 structural 
elements can be 
created in the test 
instrument, which is 
saved to the instru-
ment’s flash mem-
ory. 
or
• Create and save an existing distributor structure with the help 
of the report generating program IZYTRONIQ.
Notes concerning IZYTRONIQ
Read the online help for the PC program regarding installation 
and use.
