Exposure Control; Peak Select; Trigger, Time-Based Measurement Value Output; Error Behavior - MICRO-EPSILON ILD1402-5 Instruction Manual

Functional Principle, Technical Data
3.2.2
Dark or shining objects to be measured may require a longer exposure time. However, the controller is not
capable of providing exposure which is any longer than permitted by the measurement rate. For a longer ex-
posure time, therefore, the measurement rate of the sensor has to be reduced, see Chap. 6.4, by command.
3.2.3
For measurements on mirroring or transparent surfaces like glass plates or plastic layers spurious reflections
from the front or rear side can be suppressed by command, see Chap. 8.3.15.
3.2.4
Single measurements can be output via the trigger input. You can also output the measurements in a pro-
grammable timing period, see Chap. 8.3.10.
3.2.5
The sensor may replace or hold up to 99 consecutive errors by the last valid value. In addition, all error values
at the analog output can be replaced by the last valid value.
Details about the behaviour of the analog output can be found in Chap. 8.3.11.
3.2.6
The sensor enables an averaging of the measured values with the median or moving average, before they are
output. This does not reduce the measurement rate.
3.2.7
For a replacement or retrofitting, the ILD1402 can also be operated in the configuration of the previous type
ILD1401. This reduces the data word width of 14 to 12 bit and the functions of the ILD1401 are usable only.
3.2.8
The sensor ILD1402 uses the same commands (Stop, Info, etc.) for the same functions as the type ILD1700.
This means that existing programs of the ILD1700 can be easily adapted.
More informations can be found in Chap. 8.3.2.
