Movement analysis is done by stop motion.
- To check gaps on circular printing machine
- To inspect box and bottlings in the production line
- To inspect belt slip,& other operations of industrial machine
- To inspect the movement of weaving machine

Rotational measurement
- To check the rotational measurement and off-centering of rotating
shaft of motor, gear, pulley, fan,etc
- To check high speed rotatings of turbine,engine,etc.

TRUE READ RPM
As a characteristics
of Stroboscopes, the freezed motion may appear, or when the displayed
RPM is 1/2, 1/3, 1/4, of rotating shaft. Submultiple illusion of freezed
motion may appear when 2. 3. 4., etc. times RPM of rotating shaft
is displayed in DT-311N.
To obtain correct rpm; calibrate dial from high rpm down to low rpm.
When the first freezed motion appear, read the displayed RPM. Note:
The flashes of 1/even numbers will freeze. But avoid this case.
