Menu explanations
7.2.1
O
2
measuring ranges (scaling)
Fig. 27: O
2
measuring ranges
O
2
measuring range (3) specifies the linear scaling of the O
2
measured value as analog
output value (mA).
“O
2
measuring range from” (1) defines the O
2
value at which the analog output signal
should be 4.00 mA (4-20 mA) or 0.00 mA (0-20 mA). “O
2
measuring range to” (2) defines
the O
2
value at which the analog output signal should be 20.00 mA.
Only 4-20 mA: A measuring range underflow (4) exists when the O
2
measured value falls
below the value defined in “O
2
measuring range from”. The analog output signal is limited
to a minimum of 3.60 mA for theO
2
measured value output.
A measuring range overflow (5) exists when the O
2
measured value rises above the value
specified in “O
2
measuring range to”. The analog output signal is limited to a maximum of
20.40 mA for the O
2
measured value output. Measuring range underflows and overflows
are shown on the display (measuring mode).
7.2.2
Measured value average over [s]
This entry defines the time span up to 60 seconds for continuous averaging (rolling
average). During an adjustment as well as a sensor check, averaging for the O
2
measurement display is switched off, the signal at the analog output is still averaged.
7.2.3
mA output for system error
Sets the mA output value in the range 0 to 3.55 or 20.41 to 20.80 mA in the event of a
system error. The mA output value in case of a system error cannot be within the mA
measuring range.
Load default set.
