Manual Charging Via Weight - TESTO 570 Series Instruction Manual

Manual charging via weight

This function enables a refrigerant circuit to be charged manually via weight
using the testo 560i in combination with the app or testo 570s manifold.
By manually opening and closing the refrigerant bottle valve, the system is
charged with refrigerant until the target value (weight/superheating/subcooling)
is reached.
Displaying the current target values superheating/subcooling is only
possible in combination with testo 115i smart probes.
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 and applied to all ports tight to prevent leaks.
The system must be supervised by a competent person throughout the
entire process.
