Parameters
2.6.6. mA Output Value
Allows you to use a simulated value to test the functioning of the loop.
You can
enter 4 mA, 20 mA, or any other user-defined value within the range.
a) First set Current Output Function (2.6.1.) to Manual.
b) Enter the desired mA value in mA Output Value.
c) After completing the test, remember to reset Current Output Function
(2.6.1.) to the previous setting.
Via SIMATIC PDM:
Open the menu Device – Loop Test. (For more detail, see

2.7. Linearization
2.7.1. Volume
Carries out a volume conversion from a level value.
2.7.1.1. Vessel Shape
Defines the vessel shape and allows the LR250 to calculate volume instead
of level. If None is selected, no volume conversion is performed. Select the
vessel shape matching the monitored vessel or reservoir.
Values
Range: 3.56 mA to 22.6 mA
Read Only unless Current Output Function (2.6.1.) is set to Manual.
