Transmission measurements (%T)

Note

Parameters activated by a radio button that are not specifically mentioned in the

following procedure should be set to 'Off' (e.g., the Signal-to-noise mode radio

button). These parameters will not affect the procedure.

1. Place the accessory cap in the 'S' position, and place the protruding reference

plate in position over the reflectance port. Use the metal clamp to hold the

reference cap in position.

2. Set the following parameters:
