4. PHOTO TACHOMETER
Release the "Measuring Button" when the reading
stabilizes (about 2 seconds).
MEASURING PROCEDURE
1) Power On the meter by short pressing the " Power
button " ( 3-2, Fig. 1 ) >1.5 seconds , the LCD will light.
2) Press the " Function button " ( 3-6, Fig. 1 ) (short push) in
sequence until to the " Photo RPM " function be
selected, in the same time the " Photo light beam " (
3-16, Fig. 1 ) will be generated.
3) Apply a " Reflecting mark " ( 3-15, Fig. 1 ) to the
object being measured. and align the " Photo light
beam " ( 3-16, Fig. 1 ) with the applied target. Verify
that the " Monitor Indicator " ( 3-18, Fig. 1 ) lights
when the target pass through the light beam.
Measuring consideration :
If the measured RPM values is very low ( for
example less than 50 RPM ), recommend to
attach more " Reflecting Marks " average to
the object. It will get the real RPM with high
resolution, precisely & fast sampling time
when divided the reading values by the no.
of the " Marks ".

6 STROBOSCOPE OPERATION PROCEDURES
6-1 STROBOSCOPE OPERATION
1) Power On the meter by short pressing the " Power
button " ( 3-2, Fig. 1 ) >1.5 seconds , the LCD will light.
2) Press the " Function button " ( 3-6, Fig. 1 ) (short push) in
sequence until to the " SCOPE RPM " function be
selected, in the same time the " Stroboscope flash light (red)
indicator " (3-17, Fig. 1 ) will be Light.
3) The display will show " last measurement value " RPM ( FPM ),
last measurement value ,memo in the internal memory divice.
Use the " x 2 button(▲ button) " or " / 2 button(▼ button) " to adjust the
display value near the estimate setting signal's RPM
approximately.
*
Press and hold the " DOUBLE button " then Press " ▲ button "
once will double the display value.
For example, the display is " 100.0 " , Press and hold the
" DOUBLE button " then Press " ▲ button " once, the display will
change to " 200.0 ". Operation again, the display will change to "
400.0 ".....
*
Press and hold the " DOUBLE button " then Press " ▼ button "
once will divide the display value by two.
For example, the display is " 400.0 ", Press and hold the
" DOUBLE button " then Press " ▼ button " once , the display
will change to " 200.0 ". Operation again, the display will change
to " 100.0 ".....
6-2 Checking Speed (RPM/FPM)
1)
Use the " ▲+ button " ( 3-3, Fig. 1 ) , " ▼- button " ( 3-5,
Fig. 1 ) to adjust the exact display value.
*
Press the " ▲+ button " once will increase the display value.
*
Press the "▼ - button " once will decrease the display value.
*
Press and hold the " ▲+ button "or "▼ - button " will
fast increase or fast decrease the display value.
9
* If press the button once, the display value will
change with high resolution ( change just with 1
digit ).
* If press the button continuously, the display value will
change with low resolution ( change with more
digits ).
When checking the speed, care must be taken
to ensure that the strobe is flashing in unison
(one to one) with the object being monitored.
2) The Stroboscope will also stop motion at 2:1, 3:1, 4:1 et.,
this is normally referred to as harmonics. To ensure
unison, turn the dial until two images appear - this will
double the actual speed. Then lower the flashing rate
until a single and stationary image appears - this is the
actual true speed.
6-3 Checking Motion
For motion analysis, simply locate the actual speed as
mentioned above and use the " ▲ button " or "▼ button " to adjustment
slowly up or down. This will give a slow motion effect allowing complete
inspection.
