Error Reaction
The parameter Error Reaction defines how the switching outputs will react if a measurement cycle is found to
have been unsuccessful.
Different setting options are available in order to cause error messages to trigger different kinds of response
as appropriate for a particular environment in which the sensor operates.

Measuring Time
The Measuring Time is active in the DM and the DT measuring mode. As a general rule, it may be assumed
that the poorer the surface quality of a targeted object the more time will be required by the sensor to deter-
mine that target’s distance with specified accuracy. For example, if error message E15 is output because of
poor reflectance and too small a measuring time value, the setting for measuring must be increased.
The available range for measuring time variation is 0 to 25.
Note: The greater the value which is selected for measuring time the longer the time which will be available
for measurement and the smaller the frequency at which measurement will be performed.
“0” value setting is an exception. In this case, the sensor will use its internal criteria for evaluation.
In addition, by varying the Measuring time, one may also configure the measuring frequency. This may prove
helpful where data volumes have to be restricted. The following provides an approximated measuring time
equation:
Measuring time » Measuring Time × 240 ms (> 0)
Factory setting: Measuring time = 0.
