You can then exchange the bottom mirror module. The picture shows a

Make sure that when you have returned the bottom mirror module
holder to its position in the bottom measuring head body, you tighten the
screw to fix it in place. Also replace the cover on the hole in the
instrument. Twist it to lock it in place.
Note! The instrument does not identify the bottom mirror installed. You
must give this information in the software. When you replace the cover a
series of prompts appear on the user interface telling you to give this
information. This is described in the Reference manual in the Mirrors
chapter.
Changing the aperture
If you are going to make measurements using one of the options: Ultra
Sensitive Luminescence or HTS AlphaScreen, you must use the correct
aperture for the plate type you are using. There are three sizes of aperture,
one for each of 96-well, 384-well and 1536-well plates.
Note! In the case of instruments that do not have the Enhanced height sensor
option, the instrument does not check which aperture is installed. You must
do this manually.
1. To access the aperture you must first raise the instrument lid.
