Page 16: Application Information
General application information 7.1.1. Slowing down motion As discussed, the primary use of the testo 477 is to slow down or “freeze” the apparent motion of moving objects. This allows you to analyse their run-time performances safely and easily. To make an object appear to move in slow motion, you need to strobe it at a rate slightly above or slightly below its actual speed (or any harmonic of its speed as discussed below). -
Page 17: Harmonics
7.1.4. Determing an object’s true RPM The testo 477 can be used as a digital tachometer to determine the true RPM and/ or the reciprocation rate of an object. This is done by visually “freezing” the object’s movement and then reading the LCD display. - Page 18 7 Application information reflective tape or equivalent) in order to differentiate its orientation. • A singular image always appears at exactly one half of the object’s true RPM! Example 1 (mark needed): This example shows why identifying marks are important. Suppose you want to determine the true RPM of this fan.
- Page 19 7 Application information Image No.: Flash 3,300 2,200 1,650 1,320 Rate: Image No.: Flash 1,100 733.3 Rate: Using the orientation mark, it is now clear that the images appearing at 3,300, 1,650 and 825 RPM are multipleimage harmonics. In each of these cases, three identification marks appear.

A singular image does appear at 3,000 and again at 1,500 RPM. 1,500 is one half of 3,000. Therefore, the rate is 3,000 RPM. Pos: 34 /TD/Überschriften/x.x.
