7. MEASURING OPERATION INSTRUCTIONS
WARNING
To avoid injury, don’t aim at human eyes when measuring. Keep a safe
distance from high-speed rotating objects to avoid machine damage or per
-
sonal injury.
7.1 Mesure
1)
Paste reflective sheeting onto rotating disk or rotating shaft
2)
To avoid inaccurate measurements, rotating disk or shaft can’t be highly
reflective. If rotating disk is strong light-emitting object, cover it with black mate
-
rial before attaching reflective sheeting.
3)
Fix the tachometer in a stable position and ensure that the light emitted from
the tachometer is perpendicular to the object to be measured.
4)
Start the tachometer. Start the object to be measured. After rotation speed
is stable, press the measurement key and read the meter.
Note:
Because the meter measures and calculates the reflection time interval of light
emitted from the meter, measurement is easily interfered with by extraneous
light. Thus, measurement is not accurate if done outdoors in sunlight. Under
such conditions, using the
C-LOGIC 95
contact-type tachometer is
recommend
-
ed. If there is abnormal display due to vibrations or external light
interference,
release the key and press it again to reset the measurement
reading to zero,
and make measurements again.
7.2 Data storage and reading operation
• Data storage operation
CWhen you want to store rotation speed value, press MEM key in the non-
HOLD state. MEM and default storage number 00 will display on upper right
corner of the LCD. Press plus or minus key to select storage number. At this
time, if you pr. Press the backlight key, the rotation speed value will flash. The
current rotation speed value can be stored in the selected storage number. Exit
the storage state by pressing theREAD key under the storage state.
• Data reading operation
When you want to read stored values, press READ key in the non-HOLD state.
The default storage number 00 will display on the upper right corner of LCD.
