4. Operation
4.1 Batteries
To open the battery compartment gently press the cover lid on the left side of the handle in direction of
the arrow, see Fig. 1.
Fig. 1 Battery compartment
Insert the batteries.
Orientation as shown inside the compartment.
Close the cover lid in reverse order.
The infrared sensor thermoMETER LS is already equipped with batteries. They are protected with a plastic
strip against discharge during the transport.
Please remove the plastic strip before use.
If batteries are low the battery symbol will appear in the display, see Fig. 2,
Fig. 2 Symbol battery
Please change the batteries immediately if the symbol is flashing.
iDo not use old and new batteries together. Use only alkaline or rechargeable batteries (Type: Mignon
AA, R6, UM3)

5.1 Handling
Please hold the device as shown, see Fig. 6, and aim at the target.
Pull the trigger (1) and keep it pressed, see Fig. 6.
Fig. 6 View normal use Fig. 7 View vertical use
If the laser is activated the true size and location of the measurement spot will be shown on the object sur-
face. The temperature of the object is shown in the display (2).
The thermoMETER LS can also be used in vertical position, i.e. measurement downwards, see Fig. 7. With
this handling small objects like electronic SMD components can easily be aimed and measured.
For this purpose please hold the device as shown, see Fig. 7.
If the display switch is set to Auto (default setting) or set to On, the I button automatically gets the function
of the trigger (1) and the measured values in the display (2) are turned by 180°, see Chap. 7.3.
iPlease note, that at vertical use (Flip modes) in context with a switched display also the assignment of
the Mode buttons (I and II) will change.

5.2 Measurement Functions
The measured temperature will be shown in the main display (1). In the upper display the according maxi-
mum temperature (2) and in the lower display the set emissivity (3) will be displayed. The bar graph in the
right part of the display (4) shows temperature trends. The scaling will be done automatically between mini-
mum measured value (no segment) and maximum measured value (all segments).
Fig. 8 Display measurement functions
HOLD function
The temperature will be displayed for 7 seconds after the trigger is released. The display shows HOLD,
see Fig. 9. The device automatically switches off after this time, if no button is pressed.
Fig. 9 View HOLD

Measurement
thermoMETER LS
After taking a measurement the following functions can be displayed in turn by pressing the Λbutton (star-
ting from the HOLD mode):
Maximum value [MAX] Minimum value [MIN] Average value [AVG] Difference [DIF]
Fig. 10 Different measurement functions
MAX Maximum value determined during measurement
MIN Minimum value determined during measurement
AVG Average value (related to duration of measurement)
DIF The difference between MIN and MAX
This values will be shown in the main display, which is marked with the symbols >and <in this case. The
current temperature (in the HOLD mode: the last measured value) will be shown in the upper display.
After turning into the measure mode or after switching off the device the selected measurement function will
be kept.
Recall (Last Value)
The last measured value remains stored in the device after switch off.
To recall this value please press (in the switched off condition) the Ior II button.
The unit will be set into the HOLD mode.
In the emissivity menu the last measured temperature value can be corrected afterwards by changing the
emissivity.
