2.0 PREPARATION FOR USE
The Strobe may be hand held or mounted on a tripod or other user supplied
bracket using the ¼-20 UNC bushing at the base of the handle.
2.1 Power
The AC powered strobe must have its power cord plugged into an AC
outlet (115Vac or 230Vac).
The battery powered strobe has internal rechargeable batteries. The unit
should be charged before use (see section 7.0). The actual operating time
of the stroboscope depends on the fl ash rate and duty cycle of operation.
Slower fl ash rates (below 4,000 FPM) increase the operating time. Note
that the strobe will not operate from the recharger supplied with the unit.
2.2 Input / Output Connections
The strobe has input and output jacks on the left side of the stroboscope.
These can be used for external triggering or synchronization (daisy
chaining two or more strobes). These jacks accept 1/8” (3.5mm) phone
plugs (input - stereo, output - mono). The input and output are TTL
compatible. See Figures 2 and 3 for connector connection detail.

The input jack (p pointing into socket) enables an external signal to
trigger the strobe. Inserting a plug into the input jack will automatically
put the strobe into the External Input Mode. The INPUT button can be
used to toggle between Enternal Input Mode and Internal Mode. When
the plug is removed, the strobe will be put back into the Internal Mode.
The polarity of the input pulse can be set in the MENU options.
With no external input, the output jack (q pointing away from socket)
provides a TTL compatible pulse from the strobe’s internal oscillator.
If an external input is applied, the output pulse is in sync with the input
pulse. This output pulse may be used to trigger a second stroboscope
synchronously to illuminate larger areas. Many strobes can be “daisy
chained”. The output jack of one strobe is connected to the input jack of
the next strobe causing all the strobes to fl ash together and be controlled
by the fi rst strobe in the chain. The polarity of the output pulse can be
set in the MENU options.

Page 10
3.0 MENU
The strobe has a Menu which allows the user to select settings such as number
of decimal places, backlight on or off and positive or negative edge for input
and output signal.
To enter the MENU:
1. Press the ALT FUNCTION button and then the MENU button.
2. SETUP and the menu option will be displayed.
3. Turn the tuning knob to cycle through the main menu options.
4. Once the desired menu option is displayed, press the MENU button to
select it. Press any other button to cancel.
5. Turn the tuning knob to edit the menu option setting.
6. Press the MENU button to save your changes. Press any other button
to cancel.
7. Press any button other than MENU to exit the Main Menu.
8. DONE will be displayed.
Below is a list of the menu items:
DECPT - Decimal Point (none, 1 or 2)
BLITE - Backlight (Yes=On or No=Off)
INPUT - Positive (pos) or Negative (neg) Edge for Input Signal
OUTPT - Positive (pos) or Negative (neg) Edge for Output Signal

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.
NOTE: Unit must power down completely (OFF will be displayed and then
disappear) before unit will power on again. This is normal operation.
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 fl ash rate. In the External Input Mode, an
external signal is used to trigger the fl ash 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 fl ash rate:
With the power on, turn the knob counter clockwise to increase the fl ash
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
fl ash rate, quickly turn the knob (or use the x2 or ÷2 buttons) to coarsely
change the FPM. Then slowly turn the knob for fi ne adjustments.
6
Page 12
NOTE: There are maximum and minimum values in each mode
beyond which you cannot adjust. If you are adjusting the
rate and you reach a value which on the next increment would
exceed the maximum fl ash rate, the display will not increment.
The same is true if you try to adjust the fl ash rate below the
minimum fl ash rate.
To multiply or divide the current fl ash rate by 2:
In addition to the knob, there are two buttons on the display panel marked
x2 and ÷2. This enables the user to instantly double or halve the reading
on the display to the maximum or minimum values allowed. This feature
is useful for checking harmonics in the internal fl ashing mode.
Alternate Knob Function (multiple by 2, 3, 4, 5, etc.)
The tuning knob functions differently when ALT. is displayed. The
current fl ash rate is used as an adder. The knob will add (counter
clockwise) or subtract (clockwise) that initial fl ash rate for each “click”
the knob is turned. This in effect allows the user to multiply the initial
fl ash rate by 2, 3, 4, 5, etc up to the maximum fl ash rate. This is very
helpful on fan blades. Using this feature, one can superimpose the
blades on top of each other and check for blade tracking, bent blades,
lead and lag tests, etc.
For example: A 3 bladed fan is spinning at 3600 RPM. The strobe is
fl ashing at 3600 FPM. Press the ALT FUNCTION button to display
ALT. Then turn the knob counter clockwise 2 clicks. The strobe will
now fl ash at 10,800 FPM (effectively 3600 times 3). The fans blades
will be all superimposed on each other. One can now see if the blades
are out of alignment, bent, etc. by viewing the blades from the front or
viewing from the side edge of the blades.
7
Page 13
To select a fl ash rate from a Preset (memory) location:
1. Press the ALT FUNCTION button and then the MEMORY button.
2. READ will be displayed.
3. Turn the tuning knob to cycle through the preset fl ash rates.
4. Once the desired fl ash rate is displayed, press the MEMORY button
to select it. Press any other button to cancel.
5. DONE will be displayed.
To store the current fl ash rate in a Preset (memory) location:
1. Press the ALT FUNCTION button and then the MEMORY button.
2. READ will be displayed.
3. Do NOT turn the knob and press the MEMORY button again.
4. STORE will be displayed.
5. Turn the tuning knob to cycle through the memory locations.
6. Once the desired memory location is displayed, press the
MEMORY button to store the current fl ash rate in that location.
Press any other button to cancel.
7. DONE will be displayed.
Internal “Phase” Delay
Once the fl ash rate has been adjusted to give a stopped motion image,
the PHASE DELAY button may be used with the knob to increase or
decrease the phase of the reference mark location. Use the PHASE
DELAY button and knob to bring a reference mark, such as a key way,
into your line of sight.
To adjust the “Phase” Delay:
1. Press the PHASE DELAY button.
2. PHASE will be displayed on the bottom line and the current fl ash
rate will be displayed on the top line.
8
Page 14
3. Turn the tuning knob to adjust the location (phase) of the reference
mark.
4. Press the PHASE DELAY button again to turn the “Phase” Delay
mode off.
4.2 Internal Mode - TACH Frequency Generator
In the Internal Mode, the strobe can be used as a frequency generator
(outputting TTL pulses) without having the strobe fl ash. The pulse
output will still occur at the fl ash rate; the strobe is just not fl ashing.
To stop fl ashing:
Press the ALT FUNCTION button and then the TACH button. The
TACH icon will be displayed.
To start fl ashing again:
Press the ALT FUNCTION button and then the TACH button. The
TACH icon will go away and the strobe will start fl ashing again.
4.3 External Input Mode
In the External Input Mode the user can’t make any flash rate
adjustments. The fl ash rate is a function of the input signal. This mode
is used to synchronize the fl ash to an external event (for example, from
an optical sensor) to stop or freeze motion. The fl ash will be triggered on
the rising or falling edge (menu selectable) of the external input pulse.
The strobe is in the External Input Mode whenever there is a plug in
the input jack. When the strobe is in the External Input Mode, EXT
will be displayed.
9
Page 15
4.4 Tachometer Mode - External Input Required
When an external input is supplied to the unit and the strobe is put in the
Tachometer Mode, the unit will read the signal from the external input
(sensor) and display the reading on the LCD display without fl ashing
the lamp. The strobe will not fl ash in the Tachometer Mode.
To enter the External Tachometer Mode:
1. Plug an external input into the unit.
2. Press the ALT FUNCTION button and then the TACH button. The
TACH icon will be displayed.
NOTE: If the external input signal exceeds the maximum fl ash rate,
the strobe will go into the Tachometer Mode automatically.
To exit the External Tachometer Mode:
1. Press the ALT FUNCTION button and then the TACH button. The
TACH icon will go away.
2. The unit will remain in the External Input Mode unless the INPUT
button is pressed to change the mode.
4.5 Power Up Features
When the strobe is powered up it will remember the last settings.
Press and hold the x2/MENU button, then turn on the strobe by
depressing the trigger switch. This will turn on all the display segments
for two seconds or until you release the button. It will then show the
software revision, “REV x.x” and then go through a display diagnostic.
Press and hold the ÷2 button, then turn on the strobe by depressing
the trigger switch. This will restore the factory programmed presets.

5.0 USING THE STROBOSCOPE TO MEASURE
RPM
The primary use for a stroboscope is to stop motion for diagnostic inspection
purposes. However the stroboscope can be used to measure speed (in RPM
/ RPS). In order to do this several factors need to be considered. First, the
object being measured should be visible for all 360° of rotation (e.g. The
end of a shaft). Second, the object should have some unique part on it, like a
bolt, key way or imperfection to use as a reference point. If the object being
viewed is perfectly symmetrical, then the user needs to mark the object with
a piece of tape or paint in a single location to be used as a reference point.
Look only at the reference point.
If the speed of rotation is within the range of the stroboscope, start at the
highest fl ash rate and adjust the fl ash rate down. At some point you will stop
the motion with only a single reference point of the object in view. Note that
at a fl ash rate twice the actual speed of the image you will see two images
(reference points). As you approach the correct speed you may see three,
four or more images at harmonics of the actual speed. The fi rst SINGLE
image you see is the true speed. To confi rm the true speed, note the reading
and adjust the stroboscope to exactly half this reading, or just press the ÷2
button. You should again see a single image (which may be phase shifted
with respect to the fi rst image seen).
For example, when viewing a shaft with a single key way you will see one
stationary image of the key way at the actual speed and at 1/2,1/3,1/4, etc, of
the actual speed. You will see 2 images of the key way at 2 times the actual
speed, 3 key way at 3 times, etc. The Flashes Per Minute (FPM) equals
the shaft’s Revolutions Per Minute (RPM) at the highest fl ash rate that
gives only one stationary image of the key way.
11
Page 17
Stopped Image 1/4 times 1/2 times 1 time 2 times 3 times 4 times
Flash Rate (FPM) 1250 2500 5000 10000 15000 20000
Example: Object Rotating at 5000 RPM
If the speed is outside the full scale range of the stroboscope (20,000 FPM),
it can be measured using the method of harmonics and multipoint calculation.
Start at the highest fl ash rate and adjust the fl ash rate down. You will encounter
multiple images so be aware of these. Note the fl ash rate of the fi rst SINGLE
image you encounter, call this speed “A”. Continue decreasing the fl ash
rate until you encounter a second SINGLE image. Note this speed as “B”.
Continue decreasing the speed until you reach a third SINGLE image at
speed “C”.
For a two point calculation the actual speed is given by:
RPM = AB/(A-B)
For a three point calculation:
RPM = 2XY(X+Y)/(X-Y)2 where
X = (A-B) and
Y = (B-C)
If a Remote Optical Sensor or Magnetic Sensor is used to sense one pulse per
revolution (External mode), the readout will display directly in RPM (FPM)
without any adjustment required.
In instances when you can shut down the device and install a piece of refl ective
tape, then an optical tachometer is easier to use for RPM measurement.
Stroboscopes must be used when you can’t shut down the device. The
human eye is not easily tricked into seeing a stopped image by a stroboscope
when the fl ash rate is slower than 300 FPM. Therefore, stroboscopes are just
about impossible to use below 300 FPM for inspection or to measure RPM.

6.0 LAMP AND FUSE REPLACEMENT
6.1 Lamp Replacement
WARNING: Before attempting to remove the lamp, 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 stroboscope is designed to discharge the internal high voltages
within 30 seconds. However, caution should be exercised when replacing
the lamp.
The lamp can be replaced by using just a pocket screwdriver. It is not
necessary to remove any screws to replace the lamp.
To change the lamp:
1. Push apart the two tabs on the side of the refl ector housing and
remove the lens using a small screwdriver to help pry one tab and
lift the lens. Take care not to pry the tab any more than is necessary
to free the lens. The refl ector is held in place by the front lens and
will come loose, but it is not necessary to remove the refl ector.
2. Hold the lamp with a cloth between your forefi nger and thumb and
rock it back and forth gently while pulling out. Do not attempt to
rotate the lamp. The lamp is socketed and will come out easily
when pulled straight out.
WARNING: Do NOT touch the new lamp with bare fi ngers.
3. The lamps are polarized and must be put into the socket matching
polarity. Using a lint free cloth, match up the red dot on the
plug with the red dot on the socket and gently rock the lamp
13
Page 19
while pushing it into place (see Figure 4). Make sure the lamp is
in straight and centered in the refl ector hole.
CAUTION: Do NOT allow the refl ector to contact the lamp.

Figure 4 Lamp Replacement
4. Reinstall the refl ector and then position the front lens in place
matching up the notches on the lens with the two small tabs on
the housing to prevent lens rotation (see Figure 4). Push the tabs
on the front rim outward and press the lens into place.
14
Page 20
6.2 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 refl ector - 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.
15
Page 21
7.0 BATTERY POWERED MODELS ONLY
The HHT32R is fi tted with rechargeable NiMH (Nickel Metal Hydride)
batteries. These batteries contain fewer toxic metals than NiCd (Nickel
Cadmium) and are currently classifi ed “environmentally friendly”. They
also have 30% more capacity than NiCd batteries of the same size.
Like NiCds, NiMH batteries are prone to self-discharge - 10 to 15% of
charge is lost in the fi rst 24 hours then continues at a rate of 0.5 to 1% per
day. For maximum performance, charge the batteries just prior to use.
When not in use, the batteries should be charged at least every three months,
otherwise the battery capacity will be reduced or the batteries may become
unusable.
Charge the batteries before use and allow 3-5 cycles of charging and
discharging for batteries to reach full capacity.
The enclosure contains control electronics to properly and safely charge
the batteries. Never remove the batteries from the enclosure and attempt
to charge externally. Always use the charger supplied (HHT32R-URC).
7.1 Low Battery Indication
When the batteries are charged, there will be no battery indication. When
the batteries are low, the Low Battery icon will blink in the display. The
strobe may still be used for a short time.
Low Battery Icon = Outline blinking (very little time left)
The strobe has a protection feature that prevents the strobe from
operating if the battery voltage is too low. This condition is indicated
by no fl ash and the display shows “LO BAT”. At this time the batteries
must be recharged. Remember to release the trigger switch.
16
Page 22
7.2 Charging the Batteries
The unit may be recharged at any time. You do not need to wait until
the low battery condition is indicated.
To charge the battery powered strobe with the recharger:
1. Release the trigger so the strobe is off.
2. Plug the recharger cable into the recharger socket (located below
the display panel behind the handle).
3. Plug the recharger into an AC mains wall outlet (115/230 Vac).
CAUTION: Use of rechargers other than the one supplied
(HHT32R-URC) will damage the stroboscope
and void the warranty.
When the recharger plug is inserted into the recharger jack, the strobe
will go into the Charging Mode. Make sure the trigger switch is not
depressed. The strobe will not do anything else when charging (e.g. it
will not fl ash and the buttons have no function).
When charging, the strobe will indicate CHRGE in the bottom right of the
display. The recharger will fast charge the batteries for about 4-5 hours
and then trickle charge the batteries.
Allow the recharger to charge the batteries until the display shows DONE
for peak battery life performance. If the batteries are not charged to
100% regularly, the batteries will lose capacity.
17
Page 23
7.3 Battery Disposal
Prior to disposing of the battery-powered strobe, the user must remove
the Nickel-Metal Hydride batteries. To do this, remove the lens, refl ector
and lamp as detailed in the Lamp Replacement section. This will expose
four (4) screws that must be removed so the refl ector housing can be
dismantled. There are four (4) additional screws in the case half opposite
the input and output jacks that must be removed. The case halves can
now be separated, exposing the batteries. Unplug the batteries from
the circuit board. The batteries should be sent to a recycling center or
returned to the factory. The rest of the parts may now be disposed of.
