mA Output Value (2.6.6.)
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.
Values Range: 3.56 mA to 22.6 mA
Read Only unless Current Output Function (2.6.1.) is set to Manual.
Related parameter Current Output Function (2.6.1.)
1. First set Current Output Function (2.6.1.) to Manual.
2. Enter the desired mA value in mA Output Value.
3. 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 Loop Test (Page 78).
Linearization (2.7.)
Volume (2.7.1.)
Carries out a volume conversion from a level value.
Vessel Shape (2.7.1.1.)
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.
