There are many different kinds of sensitometers. Some use a tungsten light source, presumbably with some kind of voltage regulation to assure repeatble results. These units sometimes have an adjustment to control the output of the light. Others use pulsed Xenon flash units that allow adjustment of the duration oif the exposure and further adjustment via the use of neutral density filters. I would suggest that you do your tests at 1/100 of a second on ASA 100 film and see how close you are. This will tell you if you need to make any adjustments. Look to see if there is any way to adjust the light output. If not, you wil have to do this with neutral density filters to adjust for correct exposure.
