4.0 OPERATION

To turn on the stroboscope, depress and hold the trigger. The trigger may be
locked in position using the side locking button. To lock the stroboscope
on, depress the trigger as far as it will go and then press the locking button.
Once the locking button is set you may release the trigger and the trigger will
be held in place. To unlock the stroboscope, simply depress the trigger and
then release.

There are three major operating modes for the Strobe. These are 

Internal

,

External Input

 and 

Charging

 (Battery powered model only).  In the

Internal Mode

, the knob adjusts the flash rate.  In the 

External Input

Mode,

 an external signal is used to trigger the flash and the knob has no

effect.  The 

Charging Mode

 (Battery powered model only) is when the

strobe has the battery recharger plugged into it. The strobe will continuously
display the state of the battery charge while being recharged.

4.1

Internal Mode - Standard Strobe Operation

In the 

Internal Mode

 the stroboscope generates it’s own signals and

functions like a tunable stroboscope.  The strobe is in the Internal
Mode when nothing is plugged into the input jack or when manually
set using the 

INPUT

 button.

To change the flash rate:

With the power on, turn the knob counter clockwise to increase the flash
rate and clockwise to decrease it.  The knob is velocity sensitive.  Turn the
knob slowly to have each “click” is equal to 0.01 FPM.  Turning the knob
more quickly will adjust the FPM by larger steps.  When adjusting flash
rate, quickly turn the knob (or use the 

x2

 or 

÷2

 

buttons) to coarsely

change the FPM.  Then slowly turn the knob for fine adjustments.

Fuse Replacement

Under normal operating conditions, the fuse within the stroboscope
should never blow.  Examples of abnormal operating conditions would
be foreign materials entering the strobe, such as water, pulp, ink, etc.

The AC Powered stroboscope has a replaceable fuse inside the unit,
which may be accessed by removing the lens and reflector - refer to
Figure 4.  If the fuse needs to be replaced, replace only with a fuse of
the same type and value:  Fast Blow - 750mA, 2AG.

WARNING:

Before attempting to replace the fuse, make
sure the stroboscope is turned off and any
mains cord is removed from the AC outlet. Allow
the lamp to cool waiting at least 5 minutes.

The Battery Powered stroboscope has a resettable fuse, which will
reset once conditions are normal again.
