1.0 INTRODUCTION

The DT-105A, DT-107A DT-105A-12 and DT-1807A-12 Hand-Held Digital

Tachometers are designed to accurately measure rotation speeds, surface speeds

and length. The 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 measuring RPM, the user will mount the Cone Tip Adapter or Funnel Tip

Adapter to the end of the shaft and place in contact with the rotating shaft or

element. When measuring surface speed or length, the 6 inch circumference

(1.9" diameter) is fitted to the end of the shaft and placed in contact with the

moving surface.
