Prerequisites
•
The device is connected.
•
The operating temperature of the device has been reached. The warm-up time is
approx. 30 minutes, depending on the ambient temperature.
•
The measuring head is connected.
•
The measuring head is positioned.
Approach
1.
Make sure that the measuring head is not pointed at a light source.
2.
Ensure that there are no objects within twice the working distance along the
measuring beam.
3.
Ensure that little stray light enters the measuring head. To do this, cover the meas‐
uring head with dark paper, for example. If this is not possible for constructive
reasons, point the measuring head into the void.
4.
Perform the dark balance using command
DRK
.

returns the current virtual measuring rate.
5.
If the value obtained is very high, clean the fiber face.

Performing chromatic confocal distance measurement
Important information
NOTE
The described procedure refers to point measurements. To perform surface measure‐
ments, move the measuring head over the surface with appropriate measuring equip‐
ment. In this way, a surface is assembled from individual measurements.
Prerequisites
•
The device is configured correctly (e.g. measuring rate, lamp intensity).
•
The correct chromatic measuring head is used.
Approach
1.
Check whether the measuring head is positioned correctly.
2.
In the OD7000 Engineering Tool: Select the desired signal. Track the measure‐
ment.
3.
Adjust parameters if necessary.
Typical parameter adjustments for chromatic confocal distance measurement:
°
Measuring rate
°
Lamp intensity
°
Detection threshold
°
Detection window
