What can I do if my colorimeter gives no transmittance?
Check to see if the infrared LED is in its housing.
To do this, grasp the four rubber feet with a pair of pliers and remove them in a peeling motion. Remove the four exposed screws and bottom cover.
In the squarish LED housing area, if the LED is dangling freely, apply a very small amount of glue and insert it back into the housing.
