  • Page 2 Warning Do not look directly at strobe/reflector. Light pulses at the frequency greater than 5 Hz may cause photosensitvie epilepsy in some individuals if directly viewed. A feature of the instrument is to make moving objects appear to be stationary. Precaution should therefore be taken to ensure that there is no physical contact made with objects being viewed.

    4. STROBOSCOPE MEASURING PROCEDURES 4-1 Preparation 1)Install the batteries ( UM1/D type, 4 PCs ) into the Battery Compartment ( 3-17, Fig. 1 ) * Please make attention the polarity of the battery. 2)Turn the power switch to " Power On/Off Switch " ( 3-1, Fig.
  • Page 12 Consideration : * During the measurement, If the object mark look like rotating as the counterclockwise direction, the stroboscope's flash speed is higher than the object' s RPM typically. It should decrease the Stroboscope's FPM value will get synchronize ( mark stop ). * During the measurement, If the object mark look like rotating as the clockwise direction, the stroboscope's flash speed is lower than the object's RPM.

    4-3 Checking Motion For motion analysis, simply locate the actual speed as mentioned above and then turn the dial slowly up or down. This will give a slow motion effect allowing complete inspection. 4-4 External trigger The stroboscope can accept the external trigger signal instead of the internal trigger ( setting the value by knobs ).
