First steps

▷Inserting batteries:

To open the battery compartment, push the battery cover down.
Insert batteries (2x 1.5 V type AAA). Observe the polarity!
To close the battery compartment, push the battery cover back on.

▷ Basic settings (configuration mode): Adjustable functions

Unit of temperature: °C, °F
Differential temperature Dt: OFF, ON
Emission factor: e · 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.

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) e 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

When switching the instrument on, press and hold until and appear on the display (configuration mode).
● The adjustable function is displayed. The current setting flashes.
Press several times until the desired setting flashes.
Press to confirm the input.
Repeat steps 2 and 3 for all functions.
● The instrument changes to measuring mode.

Using the product

▷ Switching the instrument on:

Press .
– Measuring mode is opened.
▷ Switching the display light on:
****The instrument is switched on.
Press .
– The display light goes out automatically if no key is pressed for 10 seconds.
▷ 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
---|---
10cm| 3cm| 4 in| 1.06 in
60cm| 11cm| 25 in| 4.56 in
100cm| 18cm| 40 in| 7.06 in
200cm| 35cm| 80 in|

Press and hold .
– flashes in the display. The laser dot marks the centre of the measuring surface.
– When IR measurement has been completed (release ), the instrument changes to the Hold display view and the eadings are held.
▷ Changing the display view: Adjustable views

Hold: Readings are held.
Max: Maximum values since the instrument was last switched on or last reset.
Min: Minimum values since the instrument was last switched on or last reset.

Press several times until the desired view appears.

▷Resetting Max/Min values:

Press several times until the desired view appears.
Press and hold until – – – – appears.
Repeat steps 1 and 2 for all values that are to be reset.

▷Switching the instrument off:

Press and hold until the display goes out.

Maintaining the product

▷Changing batteries:

To open the battery compartment, push the battery cover down.
Remove used batteries and insert new batteries (2x 1.5 V type AAA). Observe the polarity!
To close the battery compartment, push the battery cover back on.

▷ Cleaning the housing:

Clean the housing with a moist cloth (soap suds) if it is dirty. Do not use aggressive cleaning agents or solvents!
