HIOKI Functional Units for the MR Series Memory Recorders
Most of the HIOKO memory recorders have a high flexibility due to a modular design. Each recorder consits of a main unit that forms the framework for the system (depending on the model eg. with display, PC communication interfaces, storage meory options etc.). It offers several slots that can be equipped with functional I/O units. These I/O modules define the I/O channels of the system and with this determin the measurement functions. Several units can be combined to offer exactly the channels required for individual applications.
Note, that not all modules can be used in all man units. Moreover, in some devices certain combinations of units may be not supported (see datasheets for detailed information).
