You can find complete instructions for a crayfish ERG experiment in my
online lab manual:

tinyurl.com/bio301

​Look for Lab 6, "​Electroretinogram of the crayfish eye."  The lab has
students measure and plot the latency and amplitude of the ERG for
different light intensities, using strobes to generate flashes and neutral
density filters to control intensity. (Relative intensity is much easier to
control than wavelenth selectivity, where it is difficult to generate
stimuli at different wavelengths of equal photon densities).

best,
Richard
