50% = at a concentration of 50% of the measuring point range the
output will be set to 10V (20mA without JP5 mounted)
100% = at a concentration of 100% of the measuring point range
the output will be set to 10V (20mA without JP5 mounted)

Do not change – If doing so a small “noise signal” (step form) on
top of the measured ppm-value with a duty-cycle of app. 180s is
activated.

output signal
0 V.
0V = at the minimum measuring signal of the sensor, the output will
be set to 0V (0mA without JP5 mounted)
2V = at the minimum measuring signal of the sensor, the output will
be set to 2V (4mA without JP5 mounted)

AO Function
The configuration of the analog outputs.
The analog output checks the current signal for
validity. Signal deviations of more than 5% from
the nominal value will entail an error message
(causes: short circuit or interruption of cable,
actuator not connected).
If more than one measuring points is present,
the maximum value of the two measurement is
assigned to the output.
Using this function, it is possible to configure the
output signal.
The CO2 sensor with a range of 0-20.000ppm
has an output signal of 0-10V corresponding to
0-10.000ppm as default
In example this may be changed to say 2-10V for
0-20.000ppm by changing settings to “100%” and
“2V”.
