There are a variety of implementations available. We would guide you to make sure that the setup reflects your company policy.
The most common is a stand-alone machine set-up either within an occupational health or personnel department. Users are screened by request or appointment.
Networked versions allow the user to test their vision at their own workstation. Usually an office or floor administrator is appointed to control the issue of rulers and red/green filters.
Please see the powerpoint presentation for a selection of the common implementations.
