5.1.2 Y-Axis Scaling Properties
This mode automatically adjusts the y-scale of the display to zoom in on the
measured values as close as possible.
In manual mode the value range can be set by entering the min. and max.
limits of the y-axis.
5.1.2.1 Flip Y axis
Turns the measured signal upside down. Can be used for example to display
the surface of a measurement target.
5.1.2.2 Y-Scaling Type
The scaling of the y-axis can be set to one of the following methods.
•
Manual Y range:
Enables the edit fields for the user can enter the upper and lower limit
of the y–axis.
•
Autoscale Y range:
The program searches the smallest and greatest value in the visible x-
range and sets the y-limits to those values.
•
Y center on data:
This scaling mode requires the parameter
Range(mm
), here called
Y_range.
The program calculates the average of the measurement values in
the visible x-range. Then it sets the upper limit of the y-axis to
Y_range and the lower limit to average- Y_range.
5.1.2.3 Range (mm)
This parameter determines the area of interest around the mean value of the
measurement signal.
5.2 Data Acquisition
The purpose of this page is to acquire data, only. It does not change any of
the sensor’s parameters. There is one exception: it sets the transfer mode
from ASCII to binary.
This data acquisition module requires a baud rate of 115200. Also the laser
diode must be turned on.
5.2.1 Measurement Properties
5.2.1.1 Data Acquisition
The button shows ‘
Start DAQ
’ if no connection to a sensor was established. To
connect to a sensor and to start the measurement press the button once. If
the connection was successful, the button shows ‘
Stop DAQ
’. Another click on
the button stops the measurement.
5.2.1.2 Hold last valid value
If no valid target can be recognized the last valid value is kept and put out,
otherwise an error value is put out to indicate that the sensor has ‘lost’ its
target.
5.2.2 AutoZero Properties
This section offers a software distance calibration of the sensor position.
