Sav_Triggering Pressure - TESTO 324 Instruction Manual

6.2.9.3.

SAV_triggering pressure

For the measurement, it is important to ensure that the valve
upstream of the SSV is open and the valve upstream of the
consumer is closed. The pressure downstream of the controller
(secondary side) in the gas pipe must be increased. If the triggering
pressure is exceeded, the SSV is triggered, indicated by a click,
and the gas supply is blocked on the primary side. The existing
pressure at the time of the click (secondary side) is the SSV
triggering pressure.
