To determine initial sensor configuration values, refer to Table 3.A, and
specifications that accompanied your sensors, valves, and cylinders. Write
down applicable values on Worksheet 3-D.

Important: You must enter floating-point numbers and percentages as
integers, so we recommend that you write them in Worksheet 3-D in the
following format: Use an assumed decimal point position that depends on
the range value. For example:

If the Range is:
