    19 Report memory 19 Report memory The controller continuously records all relevant measurements, settings and error messages at 1-minute intervals. The internal report memory is arranged as a ring memory, i.e. the new data always overwrite the oldest report data. The report function can not be switched off but remains active at all times.
  • Page 41 By regular cleaning of the (easy to clean) interior, residues are avoided which may impair the outfit and function of the incubator. The unit can be cleaned with commercial stainless steel cleaning agent. Please note that objects liable to rust must not be placed into the interior. Rust sediments lead to contamination of the interior or the external casing.
