3. Figure 6.7 specifies the AAR allowable tolerances for the STD and VTP of
each valve model covered in this document. Depending on the initial STD

a. If the pressure indicated is below the acceptable AAR tolerance for
valve setting, rotate the adjustment screw clockwise and test again.
Repeat this process until the desired STD value has been established
then record the pressure (Figure 6.8 & 6.9).
