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 

ALT.

  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.
