The measurement of metallic surfaces, in particular,
requires a careful emissivity adjustment on the basis
of the relevant values shown in the emissivity table.

1) Shiny or polished metallic surfaces may result in inaccurate
reading results. Please see „Emissivity" for measuring surfaces.
Accessories
Included:
1) Manual/Warranty
2) 9V alkaline battery
3) Wrist strap
4) Pouch; Make sure, that you insert
the thermometer into the pouch
like shown in order to avoid
unintended operation.
Optional:
DKD traceable calibration certificate
Distance and spot size
Due to the precision glass optics and its focusing, the
measuring
beam of the instrument has a diameter of 13
mm at any distance within 140 mm. The spot size grows
with increasing distance. At the distance of 1 m the spot
size achieves a diameter of 5 cm. The ratio of distance to
A size, also called optical resolution, is 20:1 within the
close focus point at a distance of 1 m,
|
The spot size of longer distances can be calculated by
dividing the distance by factor 20.

Spot Size
The target area must be at least as large as the spot size.
The thermometer enables you to measure objects as small
as 13 mm.

2) Infrared thermometers measure the surface
temperature of objects, only. They cannot measure
through transparent material such as glass or plastic.
3) Keep the optics clean of steam, dust, smoke or
other particles to prevent inaccurate measurement.
WARNING
Laser Class 2
>
Do not point the laser
directly at the eye or
indirectly off reflective
surfaces as this may cause
serious damage!

Buttons
Trigger:
The round button is the
trigger for the temperature
measurement. By
activating it you start the
temperature measurement,
As soon as you release the
trigger, the temperature
value will be held
for 7 seconds. The MAX- or MIN-value of the
measurement is displayed.
Mode-Button:
The centre button — marked with a circle — is the mode
button. Each time you press it, you enter another
function interface, e.g, one time to call emissivity,
afterwards. press it one time to store it, two times to
call MIN/MAX function, press it one more time to store
this function a.s.o,
Up/Laser:
With this button you set the laser and increase the
chosen value,
Down/Display Backlight:
Use this button to activate the backlight and to reduce
the chosen value,

Warranty
Each product passes through a quality process.
Nevertheless, if failures occur please contact the customer
service at once.
The warranty period covers 24 months starting on the
delivery date. After the warranty is expired the
manufacturer guarantees additional 6 months warranty
for all repaired or substituted product components.
Warranty does not apply to electrical circuit breakers,
primary batteries and damages, which result from misuse
or neglect. The warranty also expires if you open the
product. The manufacturer offers a 3 months warranty
for rechargeable batteries. The manufacturer is not liable
for consequential damage.
If a failure occurs during the warranty period, the product
will be replaced, calibrated or repaired without further
charges. The freight costs will be paid by the sende. The
manufacturer reserves the right to exchange components
of the product instead of repairing it. If the failure results
from misuse or neglect the user has to pay for the repair.
In that case you may ask for a cost estimate beforehand.
CE - Conformity
The product conforms to the following standards:
EMC:
EN 61326-1
Safety standards:
EN 61010
-1
EN 60825-1
The product accomplishes the requirements of the EMC
directive 89/336/EEC and of the low voltage directive
73/23/EEC.
The instrument complies with the standards of the
European Union.
