Constant rebar potential mode

Constant rebar potential mode In this mode the current output is adjusted continuously to provide a constant (preselected) rebar potential. A method that may be used for immersed concrete where potentials are relatively uniform and stable, the rebar potential, measured continuously with reference electrodes, is fed back to the rectifier unit. Successful operation in this mode depends on minimizing the IR drop error in the rebar potential measurements and on the accuracy and stability of the reference electrodes over time. 

Constant voltage mode In this mode a constant output voltage is maintained by the rectifier. The applied current then changes with variations in circuit resistance. Low concrete resistance, often associated with increased risk for corrosion damage, can result in increased current output. It should be noted that in this mode, the rebar potential is not necessarily constant. It can again be monitored with a reference cell.
