III. Operation Instructions
1．Starting up
Load four 1.5V AAA batteries (the anode and cathode directions
according to the identifications in the battery case). Long press
ON/OFF key to switch it on or off, and short press this key for
function selection.
2. Photoelectric rotation speed:
A: Stick one reflective marker on the object to measure.
B: Long press ON/OFF to switch it on, short press ON/OFF to
select the measurement mode photo RPM, and remove the
contact accessory installed, if any.
C. Press TEST key to make the visible beam and the measured
target in a line. Release the TEST key after the displayed value
stabilizes and the measured maximum, minimum and the last
displayed values will be automatically stored in the instrument.
D．Press MEM key to display the maximum, minimum and the
last measured values.
3. Contact rotation speed
A. Short press ON/OFF to select the measurement mode: contact
RPM, and install the contact accessory.
B. Get the contact rubber head close with the measured object
and make it rotate in sync with the measured object.
C. Press TEST key to start measuring, and release the TEST key
after the displayed value stabilizes and the measured values will
be automatically stored.
D. Press MEM key to display the maximum, minimum and the
last measured values.
4. Contact line speed
A. Short press ON/OFF to select the measurement mode: m/min
(metric system), and install the contact accessory.
B. Get the contact accessory close with the measured object and
make it rotate in sync with the measured object.
C. Press TEST key to start measuring, and release the TEST key
after the displayed value stabilizes and the measured values will
be automatically stored.
D. Press MEM key to display the maximum, minimum and the
last measured values.
5. Measurement Notes

A: Reflective marker: Cut off 12mm square adhesive tapes, and
stick one on each rotation axis. Pay attention that the
non-reflective area shall be larger than the reflective area. If the
rotation axis obviously gives out light, first smear it with black
paint or stick black tape, and then stick reflective marker thereon;
rotation axis surface must be clean and smooth before sticking of
the reflective marker.
B: Measurement of low rotation speed: To improve the
measurement accuracy, user is recommended to evenly stick
more reflective markers on the measured object when the rotation
speed is very low, and then divide the reading on the display by
the number of reflective markers to obtain the actual measured
value.
C. Please take out the batteries if not to use the instrument for a
long time, so as to avoid damaging the instrument by corroded
batteries.
6. Description of MEM Function
When TEST key is released, the display will display “0”and
current measurement mode, but the measured maximum,
minimum and the last measured values are automatically stored
in the instrument, and at this time, press MEM key for it to
display the measured values, wherein “MAX”means maximum,
“MIN”means minimum, and “LA”means the last value. Each
time the MEM is pressed, another memorized value will be
displayed.
7. Battery Replacement
A. When batteries are lower than 3.7V, LCD will display
icon to prompt for battery replacement.
B. Open the battery cover and take out batteries, and then
correctly install batteries according to the identifications in the
battery case.
