Contact and non-contact tachometer / English
1. FEATURES
The Digital Tachometer provides fast and accurate Contact and Non-Contact RPM and
surface speed measurements of rotating objects.
Measurement type: Rotation Speed (RPM,rPm), Total revolutions (REV),
Frequency(HZ),Surface Speed(M/M,I/M,F/M,Y/M) and Length(M,In,FT,Yd).
Wide measure range and high resolution.
High visible digital LCD and Backlight display.
40 reading memories : 10 selectable MAX measurements, 10 selectable MIN measurements,
10 selectable AVG measurements, 10 selectable DATA measurements.
Laser sighting.

3. Operation
Flip open the battery compartment cover and install a 9V Battery.
Non-Contact: Stick the self-adhesive reflective tape on the object whose rotational speed
is to be measured. The reflective tape should be stocked as close to the outer edge of the
object to be measured as possible.
Contact: Attach the contact adapter to the tachometer. Select the adapter included and
slides it onto the shaft of the contact adapter. Align the adapter with the alignment pin on
the shaft of the contact adapter.
