These operating instructions are an integral component of the device. They must be
accessible at all times and passed on to future users. If there is something you do not
understand please contact your supplier.
The manufacturer reserves the right to continue to develop this device without docu-
menting this in all cases. Your supplier will be pleased to inform you of updates to these
operating instructions.
1. Intended use
This device is intended for monitoring the movement of rotating and vibrating objects. It may
only be used in accordance with these operating instructions. No alterations may be made to
the device. The manufacturer is not liable for damage resulting from improper or non-intended
use. In this case the right to claim under guarantee is rendered void.
2. Safety advice
The device may not be opened, other than to change the battery (see chapter 5).
WARNING! In stroboscopic light, moving objects appear to be still or in slow motion. Do not
touch the objects under any circumstances.
WARNING! The device may not be used in areas where there is a danger of explosion.
WARNING! Stroboscopic light can trigger epileptic ts in susceptible people.
ATTENTION! Repairs on the device may only be carried out by the manufacturer or the supplier.
ATTENTION! The electronic components of the device contain substances which are harmful
to the environment. They must be disposed of in compliance with the environmental guidelines
which apply in the country of use.
3. Switching on the device
To switch on the device, please follow these instructions:
• Place batteries / charged rechargeable batteries (optional) into the device.
• Point device towards moving object and switch on. To switch the device on
hold down button A for approximately 3 seconds.
• The device will ash at the most recently set frequency. The display shows the set
ash frequency in ashes per minute.
If the ash frequency corresponds to the motion frequency, a static image will be created. If
necessary, reset to the default settings by pressing buttons B and F simultaneously.
INFORMATION! Static images are not only created at a precisely corresponding ash frequen-
cy, but also at multiples and fractions of this frequency.

5. Information on use of special functions
PULS μs / PULS deg
Flash duration. This function enables you to set the ash duration. Using this function, you can
inuence the brightness and focus of the object of observation. This adjustment can either be
made in absolute form (microseconds) or in relative form (degrees).
DELAY ms
Adjustment of delay time between the internal trigger signal and the ash (in milliseconds). This
function enables you to set a xed delay time between the internal trigger signal and the ash.
Example: The position of observation can be adjusted extremely precisely without altering the
ash frequency. You can shift the observation position within a motion cycle.
PHASE deg
Phase shift adjustment between the internal trigger signal and the ash (in degrees, relative to
the frequency). This function enables you to set a xed angle between the internal trigger signal
and the ash.
Example: The position of observation can be adjusted extremely precisely without altering the
ash frequency. You can shift the observation position within a motion cycle.
6. Changing the batteries
Using batteries/rechargeable batteries which are not completely charged reduces the operatio-
nal life until the next battery change. Never use or store the device with the battery compartment
uncovered.
How to proceed:
• Switch off device
• Unscrew the screws on the back of the device
• Remove batteries
• Insert new, charged batteries
• Dispose of old batteries in an appropriate way or recharge them (rechargeable batteries)
7. Scope of delivery
• Stroboscope, operating manual, certicate, batteries, case
Additional scope of delivery for the version with trigger connection:
• Cable with plug for trigger signal
8. Accessories, optional
• Tripod adapter, tripod, calibration certicate, belt pouch

Instructions on the use of special device functions in the version with
trigger connection (DSL-300-T)
DELAY ms
Adjustment of delay time between the internal trigger signal and the ash (in milliseconds). This
function enables you to set a xed delay time between the input signal and the output signal.
Example: The external trigger signal is generated before the required observation point
(= ash position of the stroboscope). In this case the connected stroboscope would regularly
ash too soon. With the DELAY ms function, you can set the value by which the output signal
should be delayed.
PHASE deg
Phase shift adjustment between the internal trigger signal and the ash (in degrees, relative to
the frequency). This function enables you to set a xed angle between the internal trigger signal
and the ash.
Example: The external trigger signal is generated before the required observation point (=
ash position of the stroboscope). In this case the connected stroboscope would regularly ash
too soon. With the PHASE deg function, you can adjust the delay so that the ash position of
the stroboscope is altered by a set angle. This setting is independent of the current speed of
rotation, which means that the stroboscope will ash at the required position even during the
start-up process or when the speed of rotation is uctuating.
DIV (pulse divider)
This function is only active when an external trigger signal is employed. With the pulse divider
you can set a value x, by which the external trigger signal is then divided.
Example: An external trigger (e.g. rotation sensor) scanning a gear wheel issues a signal for
every tooth scanned. At a DIV value of 10, only every tenth input pulse is transmitted to the
connected stroboscope as a trigger signal.
OPT
Trigger signal edge selection. 0 = positive edge, 1 = negative edge. With this option, the polarity
of the trigger signal can be dened.
9. Additional operating information for the version with
trigger connection (DSL-300-T)
ATTENTION! Do not use signals over 300,000 FPM Hz to trigger the device.
INFORMATION! The device must be switched manually between external and internal trigger
signal.
RECOMMENDATION: Only use original material from the manufacturer for trigger signal con-
nection.
Terminal connection assignment – trigger jack (Figure 2)
ATTENTION! Please observe the terminal connections shown in the terminal connection dia-
gram (Figure 2).
The trigger input is potential-free. The potential-free input is suitable for PNP and NPN signals.
A cable with plug, corresponding to these input jacks, is provided with the device.
