The unit must power down completely (OFF will be displayed and
then disappear) before unit will power on again. This is normal
operation. Wait 2 seconds before turning the unit back on.
3.0 LED STROBE OPERATION
3.1 Adjusting the Flash Rate - RPM
The flash rate can be adjusted by turning the knob on the side of the
unit – counter clockwise to increase the flash rate and clockwise to
decrease the flash rate. The knob is rate sensitive; the faster you turn
the knob, the greater the change in flash rate. The smallest adjustment
is to add or subtract one from the least significant (right most) digit on
the display.
3.1.1 Multiply or Divide By 2
The strobe flash rate can be instantly doubled (x2) or halved
(÷2) by pressing the
x2
and
÷2
buttons (shown right). This
is useful in determining actual rotational speed. Refer to
section 4.0 on speed measurement for more information.
Note that if doubling or halving the flash rate will cause the
strobe to exceed its capability, the display will show OVER
or UNDER respectively and the flash rate will remain at the current
flash value.
3.2 Adjusting the Flash Duration (Brightness)
The flash duration (the width of the LED flash) can be adjusted by the
user to be a preset number of degrees of rotation (DEGS) or a fixed
number with in microseconds (uSEC). The result is a more or less bright
image at the expense of less or more image blur. Read section 4.0 on
Brightness for more detail.
