frequency

Hello,
Can someone PLEASE help me. I am trying to figure out how to make the stamp
measure frequency using PULSIN with a BS2p. The manual says about this on page
241 under Explanation, but gives no example of how it can be used. I must use
PULSIN for the speed, The frequency range that I will be reading is 25Hz -
500Hz. I don't need to know the frequency just the Units.
I have tried to find a pattern using the inverse of the frequency and I got
lost.
Please Help.
Thanks
AC

Never mind about the last post I figured it out. But know I have another
problem. I need help with this math formula:
(( 1 / ( units*.00000075 )) / ( A / 2 )) *60 = B
the maximum value for units is 65535
the lowest value for units is 2670
The value for A will be between 12 and 4
Dose anyone know if the PAK-I can handle this formula?
Thanks

offline using our Fconvert program. Then you could read your units and A
values "on the fly". The rest is just multiply and divide.
