WARNING!!
To avoid injuries to animal or human
eyes,Please do not point the laser beam in
eyes or look directly into beam. If the
instrument is not to be used for any
extended period, Please remove battery.
1. FEATURE
*This Digital Tachometer provides fast and
accurate Non-contact RPM and surface speed
measurements of rotating objects.
*This tachometer is used the CPU technique,
photoelectrical technique, and junction laser
technique for one instrument combined
PHOTO TACH. (RPM&REV)
*Two test modes: rotate speed mode (unit:
RPM) &count mode(unit: REV)
*Wide measure range and high resolution.
*High visible digital LCD and Backlight
display.
*Built-in memory recalls Max Min and Last
value stored.

3. MEASURING MANUAL
Apply a reflective mark to the object being
measured. Depress the “MEAS” button and

align the visible light beam with the applied
target. Verify that monitor indicator lights when
the target aligns with the beam. Then the
current mode is the last time mode. If you
need to change the mode, release the “MEAS”
button and press the “MODE” button before
the instrument auto power off(released the
“MEAS” button this instrument will auto power
off in 10 sec) will converted between “RPM”
and “REV”(revolution). Selected the modeof
you need, depress the “MEAS” start
measures.
Press the “MEM” button can reading the
Max, Min and Last value of last time
measuring.
4. MEASURING CONSIDDERTATION
*Reflective mark
Cut and adhesive tap provide into
approx12mm (0.5″) squares and apply one
square to each rotation shaft.
a. The non-reflective area must always be

greater than the reflective area.
b. If the shaft is normally reflective, it must
be covered with black tape or black paint
before attaching reflective tape
c. Shaft surface must be clean and smooth
before applying reflective tape.
*VERY LOW RPM MEASUREMENT
As it is easy to get high resolution and fast
sampling time,if measuring the very low RPM
values, suggest user to attach more
“REFLECTIVE MARKS” averagely. Then
divide the reading shown by the number of
“REFLECTIVE MARKS” averagely. Then
divide the reading shown by the number of
“REFLECTIVE MARKS” to get the real RPM
