6. LASER PHOTO TACHOMETER
MEASURING PROCEDURES
1)Select the " Stroboscope, Ext. Trigger, Tachometer
Switch " ( 3-4, Fig. 1 ) to the " Tachometer " position.
2)Select The " Photo Tach, Contact Tach, ft/min.. m/min
Switch " ( 3-5, Fig. 1 ) to the " Photo Tach " position.
3)Adhesive a reflecting mark to the object being measured.
Align the " Laser light beam " ( 3-12, Fig. 1 ) with the
applied target. Verify that the " Monitor Indicator "
( 3-15, Fig. 1 ) lights when the target pass through the
light beam.
Note :
If the measured RPM values is very low ( for example
less than 50 RPM ), recommend to attach more "
Reflecting Marks " average to the object. It will get the
real RPM with high resolution, precisely & fast
sampling time when divided the reading values by the
no. of the " Marks ".
Caution :
