7.2.4 LASER in the TACHO and STROBO mode
Warning!
Risk of injury!!
Laser class 2
The stroboscope is fitted with a class 2 laser. This is located at
the LED array of this device. The laser beam can damage
eyes. For this reason, do not stare directly at the laser beam
and neverdirect it at people or animals. Wavelength: 650 nm,
output: 1 mW.
By means of a reflective laser beam, this stroboscope offers the
possibility to determine the flash rate almost automatically and
thus let moving parts appear optically “frozen”.
If you only want to measure the revolutions, you can also use the
stroboscope as a laser tachometer with disabled flash function.
7.2.4.1 Use of the laser
The stroboscope features a laser in addition to the aforementioned
settings (see sections 7.2.2 “Standard selection“ and 7.2.3 “Pro
selection“). To use the laser, you must first affix a reflective tape
(included in the scope of delivery) onto the object to be measured.
Press the button “Laser” (C) to activate the laser and direct the
stroboscope at the reflective tape onto the rotating object.
The laser beam will be reflected by this reflective tape back to the
receiving cell on the front side of the stroboscope.
As a result, the control of the stroboscope calculates the rotation
rate of the object.
7.2.4.2 Auto-Sync function
This function allows for the synchronisation frequency to be deter
-
mined very quickly, without manual adjustment or external sensor
signals. Furthermore, the additionally generated value guarantees
absolute measuring certainty.
7.2.4.3 Auto-Save function
To enable the integrated “Auto-Save“ feature, direct the strobo
-
scope at the rotating object for at least 2 seconds. The measured
frequency will be stored. After releasing the button “Laser“ (C),
the stroboscope flashes at this frequency and it can now be used
for all other settings.
Note
The stroboscope function is disabled in the TACHO mode
(LEDs off). In the TACHO mode, the backlight in the display
changes to orange.
Momentarily press the button “Laser“ (C) to activate. The laser
remains activated until the button is pressed again.
Note
By activating the laser, the laser symbol appears in the display
and the backlight changes to light-blue. When the reflective tape
is detected at low speed, the laser symbol flashes briefly. At higher
speed, it will flash continuously.
No.

Description
Trigger divider,
max. value 65,535.
- This function is only possible
when the external trigger is
selected.
- The flash frequency
0 … 600 FPM exceeds the
trigger by the value selected.
- This function is only possible
when the external trigger is
selected.
Setting the trigger signal edge
(increasing: 0, decreasing: 1).
- This function is only possible
when the external trigger is
selected.
Selected parameters can be
backed up in five separate
storage locations.
Set the desired storage loca-
tion by pressing the buttons
“PLUS” (E) or “MINUS” (D).
- Confirm the setting by pres-
sing the button “Laser” (C).
Stored parameters can be
read out.
- Set the desired storage
location by pressing the but-
tons “PLUS” (E) or
“MINUS” (D).
- Confirm the setting by pres-
sing the button “Laser” (C).

Trigger divider (DIV)
The trigger divider can be used to set a value x, by which the external trigger
signal is then divided.
Example: when scanning a cog wheel, an external trigger (e.g. rotational speed
sensor) sends out a signal for each cog scanned. With a DIV value of 10, it will
only flash once in every 10 signals.
SLOW (slow motion)
The “SLOW” function allows the viewer to view movement in slow motion. The
speed of the slow motion depends on the flash frequency and corresponds to the
value selected.
