First steps

²Inserting bbatteries:

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.

²Basic ssettings ((configuration mmode):

Adjustable functions

· Unit of temperature: °C,°F

· Differential temperature ∆t:OFF,ON

· Emission factor: ε

· 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) ε

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

²Switching tthe iinstrument oon:

iPress .

- Measuring mode is opened.

²Switching tthe ddisplay llight oon:

The instrument is switched on.

iPress .

- The display light goes out automatically if no key is

pressed for 10 seconds.

²IR mmeasurements:

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

iPress and hold .

- flashes in the display. The laser dot marks the centre

When IR measurement has been completed (release ),

the instrument changes to the Hold display view and

the

readings are held.
