GENERAL SAFETY INSTRUCTIONS
1. User’s due diligence
The HELIO-STROB micro2 has been developed and manufactured
in consideration of hazard analysis and in compliance with the
relevant harmonised standards as well as the additional technical
specifications.
Therefore, the HELIO-STROB micro2 is a state-of-the-art instru-
ment and offers a maximum of safety. This safety can be achieved
only if all required safety precautions have been taken. Subject to
due diligence, the user of this instrument shall plan such precau-
tions and supervise their execution.
At any time it should be ensured that
every user reads all safety and operating instructions before
operating the stroboscope.
these safety and operating instructions are maintained for
future reference.
the HELIO-STROB micro2 is used according to the intended
purpose (see chapter Product description).
the instruments are operated only if in perfect, fully functional
condition.
the complete operating instructions are legible and available at
the place where the instrument is used.
the instruments are operated only by adequately qualified and
authorised personnel which is regularly trained in all aspects
related to occupational health and safety; this personnel knows
and follows the operation instructions, especially the relevant
safety regulations contained therein.
all safety and warning labels are clearly legible and non of
them are removed from the instrument.

2. Explanation of safety symbols used in this manual
The following symbols are used in this manual:
Safety symbols call attention to adjoining safety notes
(see fig. 1 – 3)
Instruction symbols indicate important information that should
be strictly observed (see fig. 4)
1. WARNING indicates a hazardous situation which, if not avoid-
ed, could result in death or serious injury.
2. CAUTION, used with the safety alert symbol, indicates a haz-
ardous situation which, if not avoided, could result in minor or
moderate injury
3. This symbol warns of exposure to optical radiation.
4. This symbol indicates information to be used for a better under-
standing of processes.
Page 4 Operation manual HELIO-STROB micro2
3. Special hazards
In case of users with a neurological prone-
ness to epileptic seizures, the light effects pro-
duced by a stroboscope may cause photoin-
duced epilepsy. Users with such predisposition
must not use stroboscopes!
Safety Guidelines for people wearing active
implants
When using stroboscopes, an influence of ac-
tive implants (e.g. pacemakers) cannot be com-
pletely excluded. For safety reasons we rec-
ommend that people wearing active implants
are excluded from working with stroboscopes.
Persons wearing active implants have expres-
sively to be instructed in this regard.
Operation manual HELIO-STROB micro2 Page 5
4. Basic rules on safety precautions
Do not look into the LED-radiation directly
and unprotected as this could be dangerous
for the eyes – especially over longer periods
of time.
Due to the dazzle effects caused by the LED
at short distances, the ability to see may be
disturbed in such manner as to make orienta-
tion impossible.
LED-radiation shall not be directed to the
eyes of other persons.
Do not use any strongly focussing optical de-
vices to look at the light beam.
Within professional organisations the employer /
entrepreneur has to inform the employees / in-
sured workers about the possible hazards relat-
ed to their work and the safety precautions to be
applied. This shall include the current findings
regarding hazard avoiding procedures and eye-
lid protective reflexes.
Ultra bright LED radiate a similar bundled light
as laser. Accordingly, the same regulations shall
apply for LED – especially for distances below
one meter – as for laser. However, due to the
general large radiation divergence and the lami-
nar source expansion, performance LED do not
have similar potential for danger as the bundled
laser radiation.

EC DECLARATION OF CONFORMITY
It is herewith confirmed that the product listed below
HELIO-STROB micro2
meets the safety requirements within the scope of the conformity evalua-
tion procedure of the related competent authority, which are defined in the
regulation 2004/108/EG of the European Council for the approximation of
laws of the member states with respect to electromagnetic compatibility.
The same applies to the provisions of the law on electromagnetic compat-
ibility of instruments (EMVG) as of 9 November 1992.
This declaration applies to all units that are manufactured in accordance
with the appropriate manufacturing documentation which is part of this
declaration.
For the evaluation of products regarding the electromagnetic compatibility
relevant harmonised standards have been used.
DIN EN 61000-6-1
DIN EN 61000-6-3
Design-engineering modifications that have such significant effects
on the technical specifications and the proper use defined in this
operation manual so as to change the instrument considerably shall
nullify this declaration of conformity.
This declaration shall be legally binding for the manufacturer.

PRODUCT DESCRIPTION
1. Proper use
The HELIO-STROB micro2 is an LED stroboscope (light flashing
instrument) for industrial applications. This instrument is used to
produce snap-shots of sequences which, due to the rapidness they
proceed, are not perceivable by the human eye.

The user, not the producer, shall assume any liability related to any
personal injury or material damage resulted from the inadequate
use of the instrument.
It’s prohibited to operate the instrument in ex-
plosionhazardous environments.

Operation
1. General Information
The functions shall be operated by pressing the keys of
the membrane keyboard. Some of the keys have more
functions. The diverse functions are differentiated by col-
our.
The main functions are assigned blue marked areas.
To activate main functions press the relevant key.
The set-up controls are assigned green symbols.
For activation of the unit press the on / off key. Subse-
quently - within approx. 2 seconds - press the relevant
key
The special commands are assigned grey symbols.
To activate a special command switch to the function
mode by shortly pressing function key , subse-
quently press the relevant command key. By pressing
the key combination once again you return to the main
functions.
Key for switching on / off and for activation of the setup
control.
After switching on, the instrument flashes with the last
set frequency. The current value will be saved
when switching off the instrument.
30 s after switching on the instrument, the display light
automatically dims for energy saving. It will take a quar-
ter of the settable operating time until the display switch-
es to the ‘standby’ - mode (display switch-off). The time
up to the complete automatic switch-off shall be selected
by using the function (see Mode 2). The
‘standby’ - mode is indicated by a red dot flashing at the
lower right corner as a “reminder”. Reactivate the display
by pressing any key (except for the on / off key).

2. Main functions
Key for switching on / off and for activation of the setup
control.
Switch-on
Switch-off - 2 seconds after pressing or by double
clicking
Blue marked key areas e.g. stands for:
Changing the flash frequency
Reading back stored frequencies
Change the flash frequency in small steps
(+/- 1 – applied to the last indication position)
and large steps
(+/- 50 – applied to the penultimate indication position)
The absolute increment depends on the frequency
range. If the selected key is kept pressed over longer
time, the repeating function ‘repeat’ is activated.
Increase flash frequency by 1 x increment
Increase flash frequency by 50 x increments
Decrease flash frequency by 1 x increment
Decrease flash frequency by 50 x increment
