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 theæ,!3%2ækey (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 theæª#ª& 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 measurement
mode.
Select backlighting by pressing the "!#+,)'(4).'ækey (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 theætrigger 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.
