  • Page 7: Safety Information

    Safety information General safety information A laboratory thermostat heats and circulates liquids according to specified parameters. This involves hazards due to high temperatures, fire and general hazards due to the application of electrical energy. The user is largely protected by the application of relevant standards. Further hazard sources may arise due to the type of tempering medium, e.g.

    7.10 Programmer (PGM) Almost any temperature/time profile can be created with the programmer. A desired bath temperature can be approached as quickly as possible or via a defined ramp. Furthermore, the pump level and the behavior of the switching outputs can be defined.
  • Page 61  Each program begins with the segment "Start". It defines at which temperature Segment 1 is to contin- ue the program. It is not possible to specify a time for the Start segment. Without the Start segment, Segment 1 would be different depending on the bath temperature at the start of the program. For heating thermostats the start temperature must be set above the actual bath temperature during program start together with a sufficient tolerance to allow reaching the set temperature without cooling (especially if no additional cooling is available).
