TROUBLESHOOTING
No laser beam is evident:
• Confirm that the POWER button is operating properly.
• Confirm that the batteries are functioning properly and that they are inserted into the tachometer with correct
polarity.
Inaccurate measurement results:
• If the surface being measured is highly reflective, it may need to be painted darker to ensure that the tachometer
can distinguish between the reflective tape and the background.
• The laser beam may not be hitting the reflective tape, or the taped area may be too small.
• Measuring distance may be to short. The minimum distance for non-contact measurements is 12.7cm
