1.1 Batteries
To open the battery compartment gently press the cover lid on the left
side of the handle in direction of the arrow (see picture). Insert the
batteries (orientation as shown inside the compartment) and close the
cover lid. Your new LaserSight is already equipped with batteries,
which are protected with a plastic strip against discharge during the
transport (please remove). If the batteries are low the battery symbol will appear in the display. Please
exchange the batteries immediately if the symbol is flashing.
Do not use old and new batteries together.
Use only alkaline or rechargeable batteries [Type: Mignon AA, R6, UM3].

2.1 Handling
Please hold the unit as shown in the right figure and aim at the target. Pull
the Trigger [1] and keep it pressed – if the laser is activated the true size and
location of the measurement spot will be shown on the object surface. The
temperature of the object is shown in the display [2].
The LS can also be used in vertical position (measurement downwards).
With this handling small objects like electronic SMD components can easily
be aimed and measured. For this purpose please hold the unit as shown in
the left figure. 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
readings in the display [2] are turned by 180°
[►Flip-Display].
Please note, that at vertical use (Flip mode) in context with a switched
display also the assignment of the Mode buttons (I and II) will change.

Measurement
2.2 Measurement Functions
The measured temperature will be shown in the main display [1]. In the upper
display the according maximum 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 minimum reading (no segment) and maximum reading (all
segments).
Hold function: The temperature will be displayed for 7 seconds after the
Trigger is released. The display shows HOLD. The unit automatically switches
off after this time if no button is pressed.
13 thermoMETER LS

Measurement
After taking a measurement the following functions can be displayed in turn by pressing the Λ-
button (starting from the HOLD mode):
Maximum reading
[MAX]
Minimum reading
[MIN]
Average reading [AVG] Difference reading
[DIF]
MAX: maximum value determined during
measurement
AVG:
average value (related to duration of
measurement)
MIN: minimum value determined during
measurement
DIF: the difference between MIN and MAX
14 thermoMETER LS

Measurement
These 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 temperature) will be shown in
the upper display.
After turning into the measure mode or after switch off of the unit the selected measurement function
will be kept.
Recall (Last Value) The last measured value remains stored in the LS after switch off. To recall this
value please press (in the switched off condition) the I- or 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.

Measurement
2.3 Display Backlight
Pull the Trigger (keep it pressed) and then press the I-button to activate/ deactivate the display
backlight. The symbol in the display flashes to confirm.
This function is not available in the Flip mode.
Default setting: On
2.4 Laser Sighting
Pull the Trigger (keep it pressed) and then the II -button to activate/ deactivate the laser. The laser
symbol in the display (only if the trigger is pulled) indicates the active laser.
Default setting: On
WARNING: Do not point the laser directly at the eyes of persons or animals! Do
not stare into the laser beam. Avoid indirect exposure via reflective surfaces!

Measurement
2.5 Optics
The LS has switchable optics. The two possible operating
modes are indicated as SF mode (Standard Focus) and CF
mode (Close Focus).
In the SF mode (standard operating mode) objects ≥16mm
can be measured. The measurement spot will be exactly
marked with the patented crosshair laser, i.e. the real size and
location of the spot is shown on the object – independently
from the distance and with no optical offset (see right figure).
In the CF mode objects ≥1mm (e.g. electronic components) can be measured. In this operating
mode a two point laser shows the spot on the target. Both laser beams cross at the focus distance
(62mm from front of housing) and indicate the minimum spot size at this distance (Diameter: 1mm).
To switch between SF and CF mode please shift the Optic switch
which is located beside the display, to the corresponding position
(see right figure).
17 thermoMETER LS

Measurement
The symbols on the housing have the following meaning:
X SF/ Crosshair laser •CF/ Two point laser
D:S (focus point) = 75:1/ 16 mm@1200 mm D:S (focus point) = 62:1/ 1 mm@62 mm
D:S (far field) = 36:1 D:S (far field) = 4:1
D = Distance from front of the unit to the object
S = Spotsize
18 thermoMETER LS

Setup Menu 1
The measured area of the object (spot size) depends on the distance. For a correct measurement
the spot size should have at least the same size like the object or should be smaller than that at all
times.
3Setup Menu 1
In this menu Emissivity, Alarm values and the Lock mode can be set up.
Each setting or change of values and parameters will be saved by pressing the Trigger or the I-
button.
To activate the setup menu the unit must be in the HOLD mode.
Trigger⇒SAVE⇒Measure mode
I⇒SAVE⇒next menu item
If none of these buttons is pressed the settings or changes done before will not be saved and the unit
switches off after approx. 30 s.

3.1 Emissivity Setting
The emissivity (ε- Epsilon) is a material constant which describes the ability of the body to emit
infrared energy. It can range between 0 and 1 (0 and 100 %) [►Emissivity].
Setting range: 0,100...1,100 (values > 1,000 = amplification)
Default setting: 0,950
HOLD⇒II ⇒ε flashes⇒Λ⇒INCREASE ε
⇒V⇒DECREASE ε
