Sketch of the electrical connections. The DAQ board, used to acquire the raw analogue signals from the rheometer, and the control units of the rheometer and Langmuir trough are all connected via USB to a PC running custom-made acquisition/analysis software, rheometer control software and Langmuir trough control software. The interfacial pressure sensor and the barrier motor of the Langmuir trough are connected to their respective control units via serial connections. The four analogue signals from the rheometer are connected to the DAQ board via the analogue input channels using single-ended connections, with all channels sharing the same ground reference.
