Non-Contact Digital Tachometer
• If no reflective marker can be attached, it must be checked whether the
reflective properties of a reflective point on the measurement object are
sufficient for rpm measurement. In this case, aim at the measurement object
from the vertical, and check whether a value is displayed. If the measurement
object displays several reflections per revolution, the number of ventilator
vanes must be set (e.g. reflective ventilator with 5 vanes) in order to obtain
correct rpm measurements.
• If the ‘OL’ symbol appears on the LCD, it means the reading is outside the
measuring range. Please keep to the permitted measuring range.
• NEVER store the product together with solvents, acids or other aggressive
substances.
• When the battery voltage is under a sufficient operation level, the symbol
will show on the LCD. The batteries will need to be replaced with new.
1.3. Maintaining the product
• DO NOT measure at a high temperature, high humidity places.
• When not using the instrument for a long time, please remove the batteries
and avoid storing in high temperature and high humidity.
