so...the reason of measuring "soak pressure" is:
-as an indicator to detect leaking in our system, 2nd stage (low side) for high pressure refrigerant with offset around 20 psi.-

is there any purpose that make us need to measure soak pressure?

cant we do it also in high side (1st stage) due to refrigerant behavior?

is there any relationship between ambient temperature and soak pressure?

anyway, thanx for the reply.
