3.5 Connection options overview

In regard to the following connection options, the testo 570 is used to
represent any manifold and can use the testo 552 as a probe via a
MiniDIN connecting cable (see Option 2).
Option 1 (recommended)
The testo 552 is connected at the point that is furthest from the

generated throughout the system in order to remove any moisture or
foreign gases that may be present.
