ST-133 Controller
Addendum
Introduction
Thank you for purchasing a Princeton Instruments cameras system. Princeton Instruments
is presently phasing in a new improved version of the ST-133 Controller. Depending on
the ship date of your system and the status of manual revision, we are including this
addendum to point out the differences between the ST-133A and the ST-133B (see
Figure 1). All operating instructions in this manual apply to the new Controller.

The design changes include:
•
Case redesign
•
Power switch re-location and replacement
•
Increased Power Rating and changed fuse requirements
Case Redesign
As part of the repackaging and enhancement of the ST-133 Controller, the ST-133A's
paneled case has been replaced with a sleeve-type case for the ST-133B. This construction
reduces electronic noise generated by variations in grounding. In addition, this redesign and
other mechanical modifications have reduced the weight by 0.5 lbs/.23 kg.
Note: Please use the front and back bezels to move and carry the Controller (see Figure 2 on
the next page).
