To change the flash rate:
With the power on, turn the knob counter clockwise to increase the
flash rate and clockwise to decrease it. The knob is velocity sensitive.
Turn the knob slowly to have each click equal to 0.01 FPM. Turning the
knob more quickly will adjust the FPM by larger steps. When adjusting
flash rate, quickly turn the knob (or use the
x2
or
÷2
buttons) to coarsely
change the FPM. Then slowly turn the knob for fine adjustments.
NOTE: There are maximum and minimum values in each mode beyond
which you cannot adjust. If you are adjusting the rate and you reach a
value on which the next increment would exceed the maximum flash
rate, the display will not increment. The same is true if you try to
adjust the flash rate below the minimum flash rate.
To multiply or divide the current flash rate by 2:
In addition to the knob, there are two buttons on the display panel
marked
x2
and
÷2
. These enables the user to instantly double or
halve the reading on the display to the maximum or minimum values
allowed. This feature is useful for checking harmonics in the internal
flashing mode.
Alternate Knob Function - Multiple by 2, 3, 4, 5, etc.
The tuning knob functions differently when

is displayed. The
current flash rate is used as an adder. The knob will add (counter
clockwise) or subtract (clockwise) that initial flash rate for each click
the knob is turned. This in effect allows the user to multiply the initial
flash rate by 2, 3, 4, 5, etc., up to the maximum flash rate. This is very
helpful on fan blades. Using this feature, one can superimpose the
blades on top of each other and check for blade tracking, bent blades,
lead and lag tests, etc.
