I recently bought a light meter to make sure my orchids get the proper light. I must confess I am having a bit of a time understanding it.

If I have the setting on X1 the instructions say that is an Over-Input with a display reading of '1'.
When I move the switch to X10 and move the sensor about 6" from the fluorescent lamp it reads 43.3
At X100 it's 04.3 Am I supposed to put zeros on the end? At 4300 footcandles it seems too much and at 430 fc not enough. It is an agricultural light meter, not for photography.
