To operate you position the probe at some point under the light out of the way of the printing frame. Once you calibrate the unit you expose in units rather than seconds. I have my BL bank calibrated so that one second equals one unit. I don't get a lot of voltage fluctuation so in practice there is very little difference in actual time between 200 units and 200 seconds.
