First steps
> Inserting batteries:
1 To open the battery compartment, push the battery cover down.
2 Insert batteries (2x 1.5 V type AAA). Observe the polarity!
3 To close the battery compartment, push the battery cover back on.

Basic settings (configuration mode):

Adjustable functions

·Unit of temperature: °C, °F
· Differential temperature Δ t: 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)

1 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.
2 Press several times until the desired setting flashes.
3 Press to confirm the input.
4 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 that 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 equalize for approx. 15 minutes.

• The instrument has a lens (90 % value) of 6:1 (distance : measuring surface) + Opening diameter of the sensor (10mm / 0.39 in):

– flashes in the display. The laser dot marks the center of the measuring surface.
– When IR measurement has been completed (release ), the instrument changes to the Hold display view, and the readings 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:
  1 Press  several times until the desired view appears.
  2 Press  and hold until – – – – appears.
  3 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.
