Cold differential set pressure

Cold differential set pressure The inlet static pressure at which an SRV is adjusted to open on the test stand. This test pressure includes corrections for service conditions of superimposed backpressure and/or low or high temperature. 

Then the Cold Differential Set Pressure (set pressure on the test bench) must be reduced by the amount of the backpressure to obtain the correct set pressure on the installation CDSP = Set - BP.
