7. Position the locating edge (1) of the probe in the sensor slot of
the cylinder. Apply the probe to the point on the stroke of the
cylinder where you want to know the velocity of the cylinder.
You can use the strap to fix the probe in place.
8. The arrow on the probe must be pointing in the direction of
motion of the cylinder (2).
9. Press "Enter" to set the instrument to standby for
measurement.
10. When the sensors have registered the passing of the piston, the
velocity appears on the display.
11. To repeat the velocity measurement, press "Enter" to set the
instrument to standby for measurement.
The position of the sensors in the probe is indicated by two marks
in the form of dots. VTM measures the time taken by the piston to
travel between the two dots and calculates the average velocity.
Usually it is the peak velocity of the cylinder before the piston
reaches the damping position that is measured.
The meter is limited to velocities up to 9.99 m/s. If you measure the
velocity in the wrong direction, "Error" appears on the display.
