1.0 INTRODUCTION

Congratulations on your purchase of a DS-2000LED or DS-2000LED-OT
portable stroboscope. The strobe is used to make objects which are
moving at high speeds to appear to move in slow motion or become
motionless. When this occurs, you can safely and easily analyze their
motion, check for proper registration, determine sources of unwanted
vibration, etc.

Typical applications include:

■ High speed assembly lines, conveyor systems, bottling operations, etc.

■ Printing presses and cloth looms

■ Motors, fans, pumps and turbines

■ Calibration and inspection equipment

■ Monitoring laboratory & research applications

Models Available

■ DS-2000LED: operates from Internal Rechargeable Battery or

AC-Power.

■ DS-2000LED-OT: same as above but includes external trigger output.

3.2 Mode Keys

On/Off Press and hold down the button for approx.

3 seconds

Mode Button Each time the Mode Button is pressed, the

gauge switches to the next setting in the
numerical order (1–10, see pages 3 & 4).

NOTE: Some modes only effect the functioning of the device when

external triggering is employed.

Increases the currently set value.
Speeds up when this button is held down.

Halves the currently set value.

Helpful Hints

■ The most commonly used formulas are indicated by an asterisk.

■ The values for “X,” “Y” and “Z” are taken in descending order. For

example, the value for “X” is greater than the value for “Y.”

■ The values are for successive singular harmonic images. Do not use

multiple images.

■ If two points are recorded, equation (1) Y gives only approximate

results. Equations (2) with (4) and (3) with (5) are more precise, but
error can be introduced due to the rounding.

■ If three points are found, Equation (6) is the most commonly-used

formula.

■ For completeness, equations (9) through (21) offer mathematical

derivations and condensed versions of Equation (6). Also included
are the formulas for calculating Sx, Sy and Sz.
