Modes
i
The sign ESC (1Bh) finishes the data output. Now the sensor waits for a new command.
7.2.1
DT......Distancetracking
Essential input parameters: SA, SD, SE, SF, ST, OF
Effect on:
RS232/RS422, digital switching output, analog output
- Distance measurement at different kinds of surfaces (varying reflectance).
- Permanent evaluation of the sensitive laser radiation.
changing reflectance: longer measuring time
sudden jumps in distance: longer measuring time
The minimum time to measure is 160 ms, the maximum time is 6 s. If the measuring signal fails to reach a
specified quality within six seconds, an error message is output.
The time to measure may also be limited by setting the ST parameter to a desired value.
7.2.2
DS ...... 7 m Distance Tracking
Essential input parameters:
SA, SD, SE, SF, ST, OF
Effect on:
RS232/RS422, digital switching output, analog output
- Distance measurement at different kinds of surfaces at close range up to 7 m
- Higher measurement rate compared to DT measuring mode.
- Within the range from 0.1 m to 0.5 m, measuring accuracy is restricted.
Measuring time (time to measure) can be limited via ST parameter settings.
