• If EPLD (U24 chip) is Rev. 0, dual pulse will not function under 25 Hz. Only single pulse will count from 25 Hz
down to 3 Hz. Above 25 Hz, dual pulse will function as normal.
• If EPLD (U24 chip) is Rev. 1 or higher, dual pulse will function from 3 Hz and higher.
• Pulse doubling will not function for input pulses below 25 Hz.
