Behavior of the analog outputs of the ODSL 30/V…
The ODSL 30/V… has an analog output with linear behavior. A current output (4 … 20mA) and a voltage
output (1 … 10V) are available to the user. In order to achieve the highest resolution possible, the range
of the analog output should be set as small as the application allows. The analog output can be adjusted
within the measurement range by configuration via the membrane keyboard and LC display (adaptation of
the characteristic output curve). The parameter
Cal.
Ana.
Output
determines whether the calibration is
to be carried out for the current or voltage output. The characteristic output curve can be configured as
rising or falling. For this purpose, the two distance values
Pos for min. val
and
Pos for max. val
for the minimum and maximum analog output value are set accordingly in the range between 200mm and
30,000mm (see Figure 3.4 and Figure 3.5).
