Battery compartment (on rear)
First steps
Inserting batteries:
1To open the battery compartment, push the battery cover
down.
2Insert batteries (2x 1.5 V type AAA). Observe the polarity!
3To close the battery compartment, push the battery cover
back on.
Basic settings (configuration mode):
Adjustable functions
· Unit of temperature: °C,°F
· Differential temperature t:OFF,ON
· Emission factor:
· Auto off function: OFF,ON (instrument switches off automatically if no key is
pressed for 10 minutes)
The emission factor has a default setting of 0.95. This is
ideal for the measurement of non-metals (paper, ceramic,
gypsum, wood, paints and varnishes), plastics and
foodstuffs.

Product description 17
Because of their low or non-uniform emission factor, bright
metals and metal oxides are of only limited use for infrared
measurement. Coatings that increase the emission factor,
e.g. paint or emission adhesive (0554 0051) must be
applied to the object being measured.
Emission factors of various materials (typical values):
Material (temperature)
Aluminium, bright rolled (170 °C) 0.04
Cotton (20 °C) 0.77
Concrete (25 °C) 0.93
Ice, smooth (0 °C) 0.97
Iron, emery ground (20 °C) 0.24
Iron with casting skin (100 °C) 0.80
Iron with rolling skin (20 °C) 0.77
Gypsum (20 °C) 0.90
Glass (90 °C) 0.94
Rubber, hard (23 °C) 0.94
Rubber, soft grey (23 °C) 0.89
Wood (70 °C) 0.94
Cork (20 °C) 0.70
Radiator, black anodised (50 °C) 0.98
Copper, slightly tarnished (20 °C) 0.04
Copper, oxidised (130 °C) 0.76
Plastics: PE, PP, PVC (20 °C) 0.94
Brass, oxidised (200 °C) 0.61
Paper (20 °C) 0.97
Porcelain (20 °C) 0.92
Black paint, matt (80 °C) 0.97
Steel, heat-treated surface (200 °C) 0.52
Steel, oxidised (200 °C) 0.79
Clay, burnt (70 °C) 0.91
Transformer paint (70 °C) 0.94
Brick, mortar, plaster (20 °C) 0.93

IR measurements:
Laser radiation! Do not look into the laser beam.
Laser class 2.
To ensure correct readings:
· Keep temperature and humidity sources which may falsify the
measurement (e.g. hands) away from the sensor.
· Keep the lens clean and do not measure with foggy lenses.
· Keep the measuring range (the range between the instrument and the
object being measured) and the surface of the object free of obstacles.
There must be no particles of dust or dirt, no humidity (rain, steam) and
no gases.
· If the ambient temperature changes (change of location, e.g.
measurement indoors/outdoors), the instrument must be allowed to
equalise for aprox. 15 minutes.
· The instrument has a lens (90 % value) of 6:1 (distance : measuring
surface) + Opening diameter of the sensor (10mm / 0.39 in):
Distance Diameter of meas. surface Distance Diameter of meas. surface
