Automatic charging by superheat

This function enables a refrigerant circuit to be charged via the target superheat
value using the testo 560i scale and the testo Smart Valve in combination with
the app or testo 570s manifold.
For this, the current superheating value is determined. Based on this
information, a target superheat value can be entered. The system is filled
automatically until the target value is reached.
Displaying the target superheat value is only possible in combination
with testo 115i smart probes.
The appropriate maximum charge value for a system must be entered
in the [Max charge]
The appropriate superheat target value for a system must be entered
on the manifold/app or recorded by the testo 605i via
Based on the specified system size the algorithm creates a maximum
weight to be filled. When this maximum weight is reached, automatic
filling is paused and must be restarted. This prevents overfilling or
incorrect filling.
When using the manifold, the app is in second-screen mode. All
settings must be made on the manifold.
Before each measurement, check that the refrigerant hoses are in
flawless condition.
The system must be supervised by a competent person throughout the
entire process.
