Bosch Professional GIS 500 Original Instructions Manual page 13

At a surface temperature of −10 °C to +500 °C, the optimum measuring distance is
between 0.75 m and 1.25 m. Below −10 °C, the optimum measuring distance is
between 10 cm and 30 cm.
The displayed reading is the average value of all temperatures measured within the
measuring surface.
Stand back from very hot objects. There is a risk of burns.
u
Do not hold the measuring tool directly against hot surfaces. The heat can damage
u
the measuring tool.
Information about the measuring conditions
Highly reflective or glossy surfaces (e.g. glossy tiles, stainless steel fronts or cooking
pots) can affect the surface temperature measurement. If necessary, mask the area to be
measured with a dark, matt adhesive tape that conducts heat well. Allow the tape to ac-
climatise briefly on the surface.
Measuring through transparent materials (e.g. glass or transparent plastics) is funda-
mentally not possible.
Consequently, the more suitable and stable the measuring conditions are, the more ac-
curate and reliable the measurement readings are.
Infrared temperature measurement is impaired by smoke, steam or dusty air.
It is therefore important to ventilate the room prior to measuring, especially when the air
is contaminated or steamy. For example, do not perform measurements in a bathroom
immediately after the shower has been used.
Once ventilated, allow the room to reacclimatise a while until it returns to the usual tem-
perature.
Measuring functions
Individual measurements
Briefly pressing the measuring button (3) once switches the laser on and actuates a
single measurement.
The measuring process can take up to half a second and is indicated by the SCAN (h) in-
dicator lighting up. Once the measurement has been completed, the laser switches off
automatically, the indicator SCAN disappears and both the most recent measurement
reading and the reading before it are shown on the display.
Continuous measurement
For continuous measurements, press and hold the measuring button (3). The laser re-
mains switched on and the indicator SCAN appears in the display. Using slow move-
ments, aim the laser at each of the surfaces to be measured, one by one.
