Standard 601-1-1 systems requirements. Anyone who
connects additional equipment to the signal input port or

medical system and is therefore responsible for ensuring that
the system complies with the requirements of system
standard IEC Standard 6011-1-8 and the electromagnetic
compatibility system standard IEC Standard 601-1-2. The
N-395 accuracy may degrade if it is connected to secondary

refereaace.
To ensure accurate readings, consider the environmental
conditions that are present and the condition of the patient. See
the appropriate sections of the manual for specific safety
information related to these conditions.
