Wöhler IR Temp 2101. Specification
1. Specification
1.1 Important information
Carefully study and observe all items of these operating instruc-
tions before commissioning the unit.
In principle, the Wöhler IR Temp 210 should only be used by
skilled personnel for its intended purpose and within the speci-
fied range of data. Any liability or warranty for results established
or for defects caused when using the unit is excluded by all
means.
Use the thermometer with extreme caution when the laser beam
is turned on. The potential damage it could cause is for hundreds
feet away.
Do not point the laser toward the eyes or face of a person or
animal.
Never look into the laser because it could damage your eyes
seriously.
Be careful not to point the beam on a reflective surface, it could
be reflected directly and damage your eyes or the eyes of other
persons. Protect your eyes if it is necesarry to use the thermome-
ter in a reflective environment.
It is forbidden to beam on any gas which explodes.

1.2 Application
The Infrared Thermometer Wöhler IR Temp 210 is used for measuring tem-
perature without contact with the target. It provides the possibility to select
the adequate emissivity for your measurement. An optional laser pinpointing
method makes the identification of the central point of the measuring surface
area possible.

3. Operation
3.1 Temperature measuring
The Wöhler IR Temp 210 has a laser pointer beam to mark the measuring
area on the object.
Turn the instrument on by pressing the blue trigger. If you only press the trig-
ger for a short moment, the display will show the actual value. After approxi-
mately 10 seconds the meter will turn off automatically.
If you hold the trigger, the meter will automatically start measuring.
To turn the laser pointer on, press the LASER key (4) while pressing the blue
trigger (1). The star-symbol indicates, if the laser is activated or not. The re-
spective status will be stored by the instrument.
Select temperature units (degrees °C or °F) by pressing the °C/°F key (2). This
is possible while measuring (holding the blue trigger) or between the mea-
surements. The units will be shown on the right of the LCD.
When the meter is powered on, press Mode key to adjust the emissivity. A
blinking ε will show on the screen and the value on the minor display beco-
mes adjustable ranging from 0.30 to 1.0. Press ▲to increase the value,
and press ▼to decrease it. To save the adjusted emissivity value, press
„MODE“ key again. Then εstops blinking and the meter returns to measure-
ment mode.
Select backlighting by pressing the BACKLIGHTING key (5). Repeat the pro-
cedure to turn the backlight off.
The IR-Thermometer automatically holds the last temperature reading on the
LCD for 10 seconds after the trigger is released. Approximately 10 seconds
after the trigger is released, the meter powers OFF automatically.
The meter automatically compensates for temperature derivations from
ambient temperature. Keep in mind that it will take up to 30 minutes to adjust
to wide ambient temperature changes. This is a result of the cooling process
which must take place for the IR sensor.

3.2 Battery Replacement
The instrument is powered by a 9V battery. A flashing display indicates that
the battery voltage has fallen into the critical region (6.5 to 7.5 V).
• Waituntiltheinstrumenthasautomaticallyturnedoffafter10seconds.
• Openthebatterycompartmentbelowthegrip.
• Installa9Vbatteryandconnectthecabletothebatteryclip.
• Replacethecover.
4. Maintenance
Clean the exterior housing with a damp cloth. Ensure that no water pene-
trates into the instrument or has contact with the infrared lens.
We recommend to clean the lens regulary. Use low pressure compressed air
to remove any particles on the lens. If the contamination can not be removed
with air, use a soft cotton swab. Any swab should be slightly damp, and very
light pressure should be applied to the lens. Do not use solvents to clean the
lens.
5. Information on disposal
You may hand in any defective batteries taken out of the
unit to our company as well as to recycling places of public
disposal systems or to selling points of new batteries or
storage batteries.
In the European Union, electronic equipment does not be-
long into domestic waste but - in accordance with Directive
2002/96/EC of the European Parliament and of the Coun-
cil of 27 January 2003 on Waste Electrical and Electronic
Equipment - must be disposed of in an expert manner. If you
do no longer need this unit, please dispose of it in accor-
dance with the applicable statutory provisions.
