2 Applications
Please read this important information!
2.1 Intended Use / Use for Intended Purpose
The METRATHERM IR BASE is a non contact temperature mea-
surement accessory instrument. It may only be used with instru-
ments that specify it as accessory.
The temperature is measured by pointing the METRATHERM IR
BASE at the surface to be measured, and reading the temperature
on the display of the instrument it is connected with. It automati-
cally compensates for temperature deviations from ambient tem-
perature.
Safety of the operator, as well as that of the instrument, is only
assured when it’s used for its intended purpose.
2.2 Use for Other than Intended Purpose
Using the instrument for any purposes other than those described
in these instrument operating instructions is contrary to use for
intended purpose.
2.3 Liability and Guarantee
Gossen Metrawatt GmbH assumes no liability for property dam-
age, personal injury or consequential damage resulting from
improper or incorrect use of the product, in particular due to failure
to observe the product documentation. Furthermore, all guarantee
claims are rendered null and void in such cases.
Nor does Gossen Metrawatt GmbH assume any liability for data
loss.
2.4 Opening the Instrument / Repairs

the manufacturer with regard to personal safety, measuring accu-
racy, compliance with applicable safety measures or any conse-
quential damages.

5 Preparation
The METRATHERM IR BASE is powered by a 9 V battery. One
battery is included in delivery; replacements must be provided.
You have to install the battery before first use and replace it later if
depleted. If the battery runs low, the low battery LED on the instru-
ments lights up.
The measurement unit can be °C or °F. The unit is set by an inter-
nal switch located in the battery compartment. If you want to
change the unit later on, also follow the steps below but without
replacing the battery
Required tools: Philips screwdriver.



 The instrument is switched off.
1. Place the instrument face down on a stable surface.
2. Loosen and remove the screw from the battery compartment
cover.
3. Unlock and remove the battery compartment cover.
4. Set the internal °C/°F switch to the desired unit.
5. Connect the 9 V battery to the battery snap.
6. Insert the 9 V battery into the battery compartment, making
sure that the wires are not damaged (e.g. squished).
7. Place the battery compartment cover onto the battery com-
partment and press it back into place.
8. Secure the battery compartment cover with the screw.
The instrument is provided with power and ready for operation.
6 Operation
The METRATHERM IR BASE is an accessory. It‘s operation is
described in the documentation of the instruments it may be used
with.
General Information for Using the Instrument
When using the instrument, make sure that the target is larger than
the instrument's spot size. The smaller the target, the closer you
should be to it. When accuracy is critical, make sure the target is
at least twice as large as the spot size. Refer to the chart printed
on the back of the instrument for more information.
The instrument automatically compensates for temperature devia-
tions from ambient temperature. However, the IR sensor needs
time (up to 30 minutes) to adjust to temperature changes.
7 CE Declaration
The instrument fulfills all requirements of applicable EU directives
and national regulations. We confirm this with the CE mark. The
CE Declaration of Conformity is available upon request.
Warning concerning a point of danger
(attention, observe documentation!)
Warning! Laser radiation
European conformity marking
The instrument and the battery may not be disposed of
with household trash.
