How long does the test machine for medium and fine cone crushing take?

In another test of cone function a light flickering at 30 flashes per second is used as the stimulus Rods are unable to respond to light flickering at such a fast frequency so cone photoreceptors are selectively tested We refer to this portion of the ERG testing as the light adapted phase and this part of the test may take 10 to 15 minutes
