During the 30-minute soak test voltage the test voltage do not lower than. If the pressure in the system to reduce pressure and increase ngahai if the supply voltage exceeds 6%, reducing the voltage down.
Soak for 30 minutes during the test, pressure test ban under pressure. If the pressure in the system to reduce the pressure and if the pressure exceeds 6% to reduce the pressure down.
During the test, soak 30 minutes no lower pressure test pressure. If the pressure in the system to add pressure to close and if excess pressure 6%, reduce the pressure down.
