NOTE
1. Bright ambient light may interfere with the reflected
beam. In some cases, it may be necessary to bring the
tachometer close to the target or to occlude the target
area.
2. The non-reflective area must always be larger than the
reflective area.
3. If the shaft or rotating object is normally reflective, it
must be covered with black tape or paint before using the
reflective tape.
4. To obtain low RPM measurement accuracy (less than
50 RPM), attach several reflective tapes evenly on the
object. Divide the value of meter readings by the number
of reflective tapes to obtain accurate measurement data.

4. MEMORY MODE

The tachometer can store 10 maximum(MAX)
measurements, 10 minimum(MIN) measurements, 10
average(AVG) measurements and 10 LAST
measurements.
1) To store the data
After the measured value is stable when measuring,
press the "MEM" button to record while the laser beam is
on("SCAN" is display on the upper left corner). The
maximum, minimum, average and last detecting value
during single measurement will be stored into a memory
set. Then the "DATA" number will increase by one.
