NOTES

1) Deviation at one half full-scale pressure from the least squares best line fit over pressure range (0 to 0.5 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.
