5.5.3 Checking STM Cuvette Cam Thread
There are no parts that require regular maintenance. It is recommended though that
the blue Cam Thread is checked for wear and positioning.
The two sensors on the left side of the Elevator Unit should be lit when the Cuvette
Holder is in place and they should have a tolerance of a few millimetre when moving
the Cuvette Holder up and down. The sensors are marked 1 and 2, see
Fig. 5:71 be-
low.

If the two sensors do not light, do as follows.
1. Loosen the two grub screws on the side and move the blue Cam Thread slightly
downwards (arrow direction), see
Fig. 5:72 below.
2. Tighten the grub screws.
3. Test if the positioning is working properly. If not, redo the adjustment.
