1. Minimum or maximum span, or any span in between, may be positioned anywhere within the operating range. For example, if a 0 to 350 mbar (0 to 5 psig) sensing element is used and the
minimum span of 1.75 mbar (2.5 psig) is set, the process indication can be calibrated to a range of -340 mbar to -203 mbar (-10 inch Hg to -6 inch Hg), 0 to 172 mbar (0 to 2.5 psig), 
172 to 345 mbar (2.5 to 5 psig), 305 to 480 mbar (4.5 to 7 psig), or any value between minimum and maximum values of operating range.
2. Capsules with the travel stops set may be pressured to this value without permanent zero shift.
