Target Laser; Miscellaneous - BASETech IRT-350 Notice D'emploi

c) Target laser
• The product features a target laser (10) that helps determine the measurement range. You can
manually activate/deactivate the target laser.
• The middle of the measuring spot is 20.5 mm beneath the laser spot.
d) Miscellaneous
• If you wish to determine the warmest and coldest points of the measuring object, scan the
object from left to right and from top to bottom (or from front to back). The maximum and
minimum readings will be temporarily saved.
• The device cannot measure through transparent surfaces (e.g. glass). Instead, it will measure
the surface temperature of the transparent surface.
• The product must adjust to the ambient temperature before it can give an accurate reading.
If you have just moved to a new area, wait until the product has adjusted to the ambient
temperature.
• Using the product to measure high temperatures at a short distance for an extended period of
time causes the product itself to heat up which may falsify readings. Adhere to the following
rule of thumb to achieve the most exact readings possible: The higher the temperature is, the
higher the distance to the measuring surface and the shorter the measuring time should be.
