Meters per Second/Feet per Second
Selection
If you want to use the chronograph in ft/sec mode, just turn it on. To register
velocities in meters/sec mode, hold down the “review” button while you turn on
the chronograph until you see the “rdY” message.
You must do this each time you turn on the chrono when meters/sec readout
is desired.
