HL-Scan's emissivity can be selected to obtain
accurate measurement readings for different
materials and surfaces (see table). Emissivity is
set to 0.90 on leaving the factory. This is the
value most organic materials have.

The emissivities shown in the emissivity table are approximations.
Surface quality, geometry or other parameters may influence the emissivity of the object being
measured.
The scanner comes with an alarm function that
is activated when the temperature measured
exceeds or falls below the temperature select-
ed. The alarm is given in acoustic form by an
audio signal and in visual form by blue and red
back-lighting. The alarm is triggered when the
temperature measured exceeds or falls below
the temperature that is set.
When back-lighting is green, the temperature
measured by HL-Scan matches the alarm toler-
ance level previously selected. The acoustic
warning signal can be deactivated. To deacti-
vate the audio signal, go to "Settings menu".

Technical Specifications
Cleaning the lens:
The lens may be cleaned with a damp, soft and
non-linting cloth if it gets dirty (do not use
cleaning agents). Alternatively, lens cleaning
fluid may be used. Never use any acid-based
or alcohol-based solvents or solvents of any
other kind.
Cleaning the enclosure
The enclosure can be cleaned with water or
mild detergent. Never use any abrasive prod-
ucts or solvents.
Care and maintenance
Nozzles (Fig. )
The following nozzles are suitable for use on
the hot air tool with HL-Scan:
• Reduction nozzle: 9 mm, 14 mm
• Surface nozzle: 50 mm, 75 mm
When using the surface nozzles, make sure the
LED light beam is not interrupted. Only use sur-
face nozzles horizontally as shown in Figure .
Please also note that the ideal measurement
area is 15 cm from the hot air tool's delivery
outlet and not from the nozzle.
Serious measurement errors can occur if
nozzles are used other than the ones listed
here.
