displayed on the interface will be temperature. Select “Pressure” and the pressure parameter

displayed on the pressure interface will be pressure. Refrigerant type will affect the pressure

parameter displayed on the interface.

Database saving of multiple systems

Click icon of “Others” on the menu bar and click “Database Save Settings” to select which system

that needs to save database. Because there is a large quantity of data in a network that contains

multiple systems, data of only one system can be saved.
