1) if measuring range 2 is set to the maximum possible v alue, the limiting
value of range 2 ... 20 mA is at 20.9 mA and of range 4 ... 20 mA at
20.8 mA.
S Analog output during FCTRL (analog output during function
control)
The following measured value outputs are possible with the
AUTOCAL procedure, in warm-up mode and in the uncoded state:
Hold: The value measured directly prior to commencement is
output unchanged. This also applies to the limits which are
output (see section 5.9.2)
Actual: The measured value is continuously updated.
Zero: see following table:
