6.2 The "extended calibration" submenu
6.2.1 "mode current N" (N = 1 or 2)
"current span"
Used to select the current span to which the measuring range is mapped.
Selection:
• 4-20 mA (default)
The measuring range (0%-100%) is mapped to the current range 4-20 mA.
• 0-20 mA
The measuring range (0%-100%) is mapped to the current range 0-20 mA.
• fixed current HART
A fixed current is output. The value can be defined in the "mA value" parameter. The measured
value is transmitted by the HART signal.
L00-FMU90xxx-19-00-00-yy-066
A: current span = 4-20 mA; B: current span = 0-20 mA; C: current span = fixed current HART;
D: mA value
"mA value" (only available for "current span" = "fixed current HART")
Specifies the value of the fixed current.
• range of values: 3,6 - 22 mA
• default: 4 mA
