Page 15: Introduction
® TitraLab 870 Reference Manual Introduction The TitraLab 870 Titration Workstation is dedicated for routine use. It offers two distinct user levels: • Supervisor Dedicated for operators who wish to edit their methods to fit their specific needs. They can also assign a password to protect the programmed data from eventual changes.
Page 16: General Information
It is therefore aimed at experienced users who have the knowledge required to op- erate the instrument and implement the security instructions enclosed. Please remember that the TitraLab 870 must not, under any circumstances, be used to perform tests on living beings.
Page 17: Starting Up
TitraLab ® TitraLab 870 Reference Manual Starting up Set up the instrument in a properly ventilated place. The power supply connector on the rear panel must remain accessible and close to the user (2 m maximum) so that you can quickly disconnect the cables in case of emergency.
