NOTES
1) Deviation at one half full-scale pressure from the least squares best line fit over pressure range (0 to 0.4 bar).
2) Slope of the endpoint straight line from 25°C to 60°C.
3) Output deviation at any pressure within the specified range, when this pressure is cycled to and from the
minimum or maximum rated pressure, at 25°C.
4) Same as 3) after 10 pressure cycles
5) Maximum difference in offset after one thermal cycle from -40°C to +125°C.
