2. INSTRUMENT DESCRIPTION

The instrument has the features described below:
• RPM speed measurements without contact
• rPm speed measurements with contact
• HZ frequency rotation measurements with/without contact
• M/Min, Inch/Min, Ft/Min and Yd/Min surface speed measurements
• M, In, Ft and Yd length measurements
• Revolutions counter number (REV)
• MAX/MIN/AVG functions
• Laser pointer for measurements without contact
• Saving and recalling results on the display
• Backlight
The instrument consists in two internal units which perform all measurements. The
emitting unit uses a red LED to emit a ray of light which is reflected by the reflecting tape
applied on the surface of the object being tested and is received by receiving unit (see §
5.1). For contact measurements, the reflecting tape is fixed inside the removable adapter.
It is recommenced that the reflecting surface should be perpendicular to the
emitting/receiving unit to obtain the best measurement results. Unscrew and remove the
mechanical adapter (see Fig. 1 – part 1) to perform non-contact measurements.
