1.0 INTRODUCTION

The DT-205LR, DT-207LR, DT-205LR-12 abd DT-207LR-12 Hand-Held

Digital Tachometers are combination models designed for Contact as well as

Non-Contact operation. They employ a precise Optical Laser System that

permits measurement of RPM from up to 14 feet away when operating in the

Non-Contact mode and is supplied with a Screw-In Contact Adapter (p/n:

DT-ADP-200LR) for measuring RPM, Surface Speed & Length in the Contact

operating mode. Rotational speed is displayed in RPM units (revolutions

per minute) while the surface speed and length can be displayed in a variety

of user-selected engineering units.

When operating in the Non-Contact mode a small piece of reflective tape

must be affixed to the rotating shaft or other rotating element. Refer to
