Setting the measuring rate
Preset measuring rates can be selected in 1 Hz steps. The measuring rate must be
selected as an integer value in the range supported by the device.
The greater the measuring rate, the shorter the exposure time. The amount of light per
measurement is lower.
The smaller the measuring rate, the longer the exposure time. The amount of light
per measurement is higher. The detector is exposed for a longer time. Due to the
longer exposure time, any stray light that may occur has a greater influence on the
measurement result. If too much light is reflected, detector overdrive occurs. Increase
the measuring rate in case of overdrive.
Setting
Application
Increase measuring rate
Perform many measurements per time unit, e.g. to
measure highly reflective surfaces.
Reduce measuring rate
Even weakly reflective surfaces can be measured accu‐
rately.
Configuration with the OD7000 Engineering Tool
The measuring rate can be set in the
Measurement settings
window. To check the settings,
open the spectrum in the
Alignment
menu.
Spectrum
Setting recommendation
The peak in the spectrum does not have a
sharp peak, but is cut off at the top.
The detector is overdriven. Increase measuring
rate.
The peak in the spectrum is too weak. The
peak is difficult to distinguish from the noise.
Reduce measuring rate.
Configuration with commands
Command:
SHZ
Example
Input
Action
SHZ 40
Sets the measuring rate of the device in Hz.
SHZ ?
Returns the current measuring rate.
7.3.2
Exposure settings
Exposure settings
Different exposure settings are available to account for surfaces with different reflective
behavior.
The device can automatically adjust the amount of light during measurement.
Configuration with commands
Command:
AAL
(Auto adapt light source
)
Example
Input
Action
AAL 1 50
Activates the automatic adjustment of the light source. Sets the target
saturation level to 50%.
AAL 0
Deactivates automatic adjustment of the light source.
