3.1. Normal Operation
a. Install four 1.5V AA size batteries.
b. Cut off a piece of reflective tape of size 1.0 cm x 1.4 cm (optimal
size)
c. Wipe off oil or stains from the surface where reflective tape will be
adhered.
d. Stick the self-adhesive reflective tape on the object whose
rotational speed is to be measured. The reflective tape should be
attached as close to the outer edge of the object to be measured as
possible.
e. Press the START button to turn on tachometer.
f. Point the photoelectric probe at the object as Figure 2. Press the
START button once and confirm that the red emitting LED lamp lights
up. Then read the rotational speed on the LCD display.
g. If the rotational speed is less than 60 rpm, it may take about 1 to 6
seconds to measure (60 rpm takes 1 second, and 10 rpm takes 6
seconds).
h. The reading will be held for 6 seconds, if you aim the photoelectric
probe at a 0 speed object right after one measurement.
Note: If the speed is less than 999.99 rpm, the red LED is turned on all the
time to detect speed. If the speed is great than 999.99, the unit goes into
power-saving mode. The LED is turned on for a very short period of time,
then turned off for most of the time to save power.
