 Some potentiostats can be operated as galvanostats. In this case the current flow is controlled while the potential is monitored.  Note that you cannot control both the current and the potential simultaneously unless you have a variable load! eDAQ potentiostats that work as galvanostats are:

 The term 'four-electrode potentiostat' is usually reserved for a device with two reference ('voltage sensing') electrodes and two working ('current passing') electrodes. The potential difference between the two reference electrodes is controlled while the current flow between the two working electrodes is monitored. These potentiostats are commonly used to measure the current flow across a membrane separating two compartments, or across the interface of two immiscible solvents (an [http://en.wikipedia.org/wiki/ITIES ITIES] experiment).
