*1 When measuring outdoors with minimal atmospheric motion, the staff set up in natural
sunlight and luminosity at the surface of the staff equal to 20lx.
*2 When measuring with no atmospheric motion or scintillation, ambient temperature is stable
and the instrument and staff are set up out of direct sunlight. Accuracy may be affected by
wind conditions and the set up of the instrument and staff.
*3 When measuring to a staff set up outdoors in fine to cloudy conditions.
*1, 3 These specifications may change depending on the weather conditions and measurement
conditions.
