Hi. I have an Ace Tachmaster II that I've had for about 16yrs and really like.

My question is, how does one calibrate this tach?

When I aim it at a fluorescent light it reads exactly 3500. Is this what it should read?

Thanks, David

Never mind!!! I just saw the little red arrow at 3600!

Thanks anyway!
