Synchronisation

The A/D IN input is synchronised with potential and current acquisitions. It can be used to record the temperature or any other useful data. The D/A OUT output is synchronised with the start of any method. It can be used to set the speed of a rotating electrode or to start or regulate any other experimental instrument.
