Because of its sensitivity, the unit does not know whether it is
looking at a propeller or an incandescent or fluorescent light,
which typically strobes at 60 cycles per second or 3600 cycles
per minute. When set for 2-blades it will read 360 or 3600,
3-blades: 240 or 2400 and 4-blades: 180 or 1800. This is a quick
way to test the calibration.
In direct sunlight this will read zero when turned ON.
