<VV> tach

[FrankCB]

Guus and Arend,
     Sorry, but you fellows know I was just speaking only for the USA where our home electrical network is maintained at 120 volts AC and 60 cycles per second.  Since Europe generally has 240 volts and 50 cps, you have to modify my values of 2400 rpm (full wave rectification) and 1200 rpm (half wave rectification) by multiplying them by 50/60 to get 2000 rpm (full wave rectification) and 1000 rpm (half wave rectification) on your tachometers.
     Lach alstublieft!

Yes so do ours......to keep them at..... 50 cps ;-) 

Arend, heb je al een oplossing, anders even bellen.
