Operating Instructions, 01/2013, A5E32122003-AA
The default value for each of these new parameters is 0.0. A value of zero effectively
disables the pressure and temperature pipe volume compensation routine. When entering a
value for the thermal expansion coefficient and modulus of elasticity, keep in mind that the
numeric entry already includes an exponent multiplier. For the Thermal Expansion
Coefficient the multiplier is 10
-6
and for the Modulus of Elasticity the multiplier is 10
6
.
Typical values for each parameter are shown below:
