Flash duration analysis for an Orlit Rovelight RT 601 HSS studio flash unit and Normal Mode settings of 9.0 for the longest flash, followed by 7.9 - 6.9 - 5.9 - 4.9 - 3.9 - 2.9 - 1.9 and finally 1.0 for the shortest pulse.
Generated by the FDM-1T flash duration meter.
For settings 3.9 and lower, measurement was triggered on the 2nd pulse. Measurement basis for all results was set to Luminous Exposure. Additionally, standard visualization was configured to show the overall luminous exposure (in lux-seconds) induced by the measured flash as an additional value at the bottom of the screen.
