Cell On/Off - BAS 100B/W Instruction Manual

5.13 Cell On/Off

When Cell On is selected, the working electrode is connected at all times. When Cell
Off is selected, the working electrode is only connected during experimental runs.
For most experiments, the cell should be off between runs, since there is more chance
of damaging the instrument (and of personal injury when using the PWR-3) if the cell
leads are connected/disconnected when the cell is on.
