6.1 Laser
The laser sighting allows fast and precise aiming at small, rapidly moving targets, or targets passing at irregular
intervals. The laser is specially aligned with the sensor’s lens to provide accurate, non-parallax pinpointing of
targets. The laser comes as a small, bright red spot indicating the center of the area being measured.
Figure 6-1: Laser Indication
The laser is a Class II type laser with an output power less than 1 mW, and an output wavelength of 650 nm.
Note
To preserve laser longevity, the laser automatically turns off after approximately 10 minutes of constant use!
Risk of Personal Injury
Avoid exposure to laser light! Eye damage can result.
Use extreme caution when operating!
Never look direct into the laser beam!
Never point directly at another person!
LASER 2
λ = 650 nm, < 1 mW, IEC/EN 60825-1 :2014
The laser automatically turns off above an internal case temperature of 50°C (122°F).
The laser is not available for the LT-07, LT-15, LTB-30, LTD-04, P3 and HART models.
2-wire devices require an additional power supply via USB. For this purpose, the end cap must be removed so that
the device loses its IP65 ingress protection.
6.2 Post Processing
6.2.1 Averaging
Averaging is used to smooth the output signal. The signal is smoothed depending on the defined time basis. The
output signal tracks the detector signal with significant time delay, but noise and short peaks are damped. Use a
longer average time for more accurate damping behavior. The average time is the amount of time the output signal
needs to reach 90% magnitude of an object temperature jump.
