9.2 Output Range
9.3 Error Output
Now the value can be defined which is to be output if the source item can not be measured.
When configuring an analog output, the output range will be defined
now. Select one of the ranges in the scroll list or
OTHER RANGE..
. to
enter the output range manually.
If
OTHER RANGE..
is selected, enter the minimum output value
(
OUTPUT MIN
). Press ENTER.
If
OTHER RANGE..
is selected, enter the maximum output value
(
OUTPUT MAX
). Press ENTER.
The entered output range should cover at least 10 % of the full physi-
cal output range (e.g.
I
MAX
- I
MIN
2 mA for a 20 mA current loop).
If this is not the case, the smallest maximum output value (
OUTPUT
MAX
) possible for the entered minimal output value (
OUTPUT MIN
) will
be displayed.

MINIMUM
output of the lower limit of the output range
HOLD LAST VALUE
output of the last measured value
MAXIMUM
output of the upper limit of the output range
OTHER VALUE
The output has to be entered manually. It has to be within the limits of the output.
Example:
The normalized refractive index was selected as source item for the current loop, the output range
was set to 4/20 mA, the error value delay t
d
> 0.
The measurement of the refractive index is impossible during the time interval t
