Recorder Output (analogue)
The two Recorder outputs (analogue outputs) may be used to log the leak rate, the
inlet pressure or the fore-vacuum pressure.
The output voltage is updated every 50 ms.
RS232 Interface
The RS232 interface serves for connecting a PC directly to the Modul1000.
The Modul1000 is then directly controlled by the respective instruction sets as
described in the interface description.
