mmmmm
Parameters
2.3.1.3. 4 mA Setpoint
Sets the process level corresponding to the 4 mA value. 4 mA always
defaults to 0, and mA Output Function determines whether this is a Level,
Space, or Distance measurement. Level and Space are measured as a
percentage of the difference between High Calibration Point and Low
Calibration Point. Distance is measured as a percentage of the Low
Calibration Point.
Enter the reading that is to correspond to a 4 mA output. Units are defined
in Sensor units for Level, Space, or Distance.
1)
Notes:
• The mA Output Function is set independently from the setting in
Operation. Set Operation first and then mA Output Function.
(Operation resets mA Output Function to the same value.)
• The mA Output Function controls the primary value and the loop
current for the SITRANS LR260. Use caution when changing the mA
Output function when connected to a HART network.
• mA Output Function must be set to Manual before you can modify the
mA Output Value (2.3.1.1). Remember to restore your previous setting
after using mA Output Function.
Values
Range: 0 to 30 m

Default: 0 m (set to value corresponding to 0% as defined
