Target Superheat
This feature allows the calculation of target superheat in conjunction with the
App and additional testo 605i Smart Probes. This application can only be used
for split air conditioning systems/heat pumps with a fixed expansion valve. The
two connected testo 605i Smart Probes determine the ODDB and RAWB
values. As a result, the target superheat appears in the App.
The following are used for the measurement:
•
testo 115i (clamp thermometer)
•
testo 605i
Before each measurement, check that the refrigerant hoses are in
flawless condition.
Before each measurement, zero the pressure sensors.
