1 Safety notes
Please read this manual carefully and completely before you usethe device for the first time. The
device may only be used by qualified personnel and repaired by PCE Instruments personnel.
Damage or injuries caused by non-observance of the manual are excluded from our liability and
not covered by our warranty.
•The device must only be used as described inthis instructionmanual. If used otherwise,
this can cause dangerous situations for the user and damage to the meter.
•The instrument may only beused if the environmental conditions (temperature, relative
humidity, …) are within the ranges stated in the technical specifications. Do not expose
the device to extreme temperatures, direct sunlight, extreme humidity or moisture.
•Do not expose the device to shocks or strong vibrations.
•The case should only be opened by qualified PCE Instruments personnel.
•Never use the instrument when your hands are wet.
•You must not make any technical changes to the device.
•The appliance should only be cleaned with a damp cloth. Use only pH-neutral cleaner,
no abrasives or solvents.
•Be particularly careful when the laser beam is activated.
•Avoid eye contact with the laser beam.
•Also avoid eye contact with the laser beam through reflecting surfaces.
•The device must only be used with accessories from PCE Instruments or equivalent.
•Before each use, inspect the case for visible damage. If any damage is visible, do not
use the device.
•Do not use the instrument in explosive atmospheres.
•It is not recommended to measure glossy or polished metallic surfaces (stainless steel,
aluminium etc.) with this meter, see information about emissivities.
•The thermometer cannot measurethrough transparent surfaces suchas glass. It would
measure the surface temperature of the glass instead.
•Vapor, dust, smoke etc. can impair the optics of the meter and thus have a negative
impact on the measuring accuracy.
•The measurement range as stated in the specifications must not be exceeded under
any circumstances.
•Non-observance of the safety notes can cause damage to the device and injuries to
the user.
We do not assume liability for printing errors or any other mistakes in this manual.
We expressly point to our general guarantee terms which can be found in our general terms of
business.

which appear during the measurement mark the diameter of the measuring spot. The complete
area within the circular measuring spot will be included in the measurement.
NOTE
Make sure the target is larger than the measuring spot. The smaller the target, the closer the
meter must be to make a measurement. If a high accuracy is required, make sure the target is
twice as large as the measuring spot.

5 Measurement
Infrared thermometers measure the surface temperature of an object. The object emits infrared
radiation which is collected by the optics of the thermometer and focused onto the sensor where
the radiation is converted to a signal that will be transmitted to the electronics. The electronics
processes the signal so that the reading can be displayed in degrees Centigrade or Fahrenheit.
The laser points mark the diameter of the circular area that will be included in the measurement.
The temperature can also be measured by using the included K-type thermocouple. This allows
measurements in areas where the infrared sensor could not be used.
1. Hold the meter by its handle and target the surface you wish to measure.
2. Apply and hold the trigger button to make a measurement. The SCAN icon will be
displayed. If the display does not light up, replace the battery.
3. Release the trigger button to stop the measurement. The HOLD icon will appear and
various functions and settings are available via the keys MODE, F1, F2 and F3.
4. The thermometer powers off automatically (standard 7 s, max. 60 s).
NOTES
•Not recommended for glossy or polished materials (stainless steel, aluminium).
•The material-specific emissivity can be set in the meter, see chapters 6.1.6 and 7.
•The meter cannot measure through transparent surfaces such as glass or plastic. It
would measure the surface temperature of the transparent surface instead.
•Vapor, dust, smoke etc. can impair the optics of the meter.
•To find a spot of critical temperature (hot spot), slowly change the targeted area
during the measurement and watch the display.
•Allow some time for the meter to adapt to the ambient temperature, especially when
there is a considerable difference between the measuring and ambient temperatures.

7 Emissivity values
The emissivity describes the energy emission behaviour of materials. Most (90 % of the typical
applications) organic materials and painted or oxidisedsurfaces have an emissivity of 0.95 which
is the standard setting in the meter.
When you measure glossy or polished surfaces, the accuracy will deteriorate. If possible, cover
the surface to be measured with temperature-resistant black adhesive tape or a thin layer of black
paint. Allow some time for the tape or paint layer to take on the same temperature as the material
below it. Now measure the temperature.

9 Warranty
You can read our warranty terms in our General Business Terms which you can find here:
https://www.pce-instruments.com/english/terms.
10 Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.
If you have any questions, please contact PCE Instruments.
